1978 1(1) 4-10 Simon J. Mayo Aroid-hunting in Bahai (Buy)
ABSTRACT: Despite having been the first area of Brazil to be colonized by the Portuguese, the north-eastern state of Bahia is still poorly-known botanically, particularly in its dry interior region. All the indications are, however, that the flora is very rich, and this applies to the aroids as well as to many other families of plants. Consequently, when in the first three months of 1977 I took part in a Kew expedition to Bahia led by Dr. Raymond Harley, I was particularly keen to refind the many poorly-known Araceae recorded from this region.

1978 1(1) 11-12 Michael Madison On the names of aroids
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: It would seem useful in this first issue to clarify some aspects of the naming of plants. The latin name of a plant species consists, technically, of three parts which appear in the following order: first the genus, which is capitalized, ego Philodendron; followed by the species, which is not capitalized, ego giganteum; followed by the name of the person who first described the species, in this case H. W. Schott. So the name of this West Indian species is Philodendron giganteum Schott. In orticultural literature the author's name is often omitted.

1978 1(1) 17-19 Michael Madison The Anthurium leuconeurum confusion
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: There are several species of Anthurium with velvety deep green leaves and silver veins which have been for years among the most prized subjects of aroid collections. Recently large numbers of these plants have become available in the nursery trade, with wholesalers supplying plants either by massive collections from the wild or by growing plants from seed, much of the latter taking place in Costa Rica. Most of the plants in the trade are distributed as Anthurium clarinervium or A. crystallinum, but there seems to be no general agreement as to which is which. The following notes should help to clarify the situation.

1978 1(1) 21-23 Simon J. Mayo The aroid collection of Roberto Burle-Marx
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: The estate of Roberto BurleMarx is near Guaratiba to the southwest of Rio de Janeiro, beyond the Serra da Pedra Branca and the Restinga da Jacarepagua, and occupies a site stretching from the top of a fairly steeply-sloping hillside to its base. The principal botanical interest of his plant collection, which he has amassed over some 30 years or so, lies in the very rich collections of Araceae, Bromeliaceae, Musaceae, Velloziaceae and Orchidaceae. As regards the Araceae, his collections of Anthurium and Philodendron spp. merit special attention, being not only of Brazilian species but also with good representation from Ecuador, Costa Rica, Panama and other parts of the neotropics in which Sr. Burle-Marx has collected.

1978 1(2) 31-53 Michael Madison The genera of Araceae in the northern Andes (Buy)
ABSTRACT: The north Andean region, which includes Colombia, Ecuador, and Peru, has perhaps the richest flora in the world and is the center of diversity of the family Araceae. The low to middle elevation wet forests of the area abound with aroids which cover the ground, climb up tree trunks, and as epiphytes adorn the outer branches of the trees. Many of our finest ornamental aroids, including Anthurium andreanum, A. crystallinum, Caladium bicolor, and Philodendron erubescens, are derived from this area. The purpose of this paper is to provide a key and brief descriptions of the genera of Araceae of the northern Andes which should enable anyone to identify to genus aroids from the region. The key is also applicable in Central America, but only partly so in the rest of South America where a number of additional genera, principally of the subfamily Aroideae, are found.

ABSTRACT: Anthurium lilacinum Dressler, Selbyana 2:300 (1978). Etymology: From the Greek anthas 'flower,' and aura, 'tail,' referring to the resemblance of an anthurium inflorescence to the tail of a mouseÂ· and Latin lilacinus, 'lilac-colored; referring to the spathe and spadi~.

1979 2(1) 15-25 Thomas B. Croat, George S. Bunting Standardization of Anthurium descriptions (Buy)
ABSTRACT: A standardization of terminology for both new species descriptions and for floristic treatments would benefit other aroid workers as well as the general users of these works, since complete and uniform descriptions allow for more accurate comparisons. Furthermore, it is necessary to define the many special terms which are necessary to properly describe the species of An thurium. Some of these terms are used here for the first time, and while they are intended especially for use with Anthurium, many are equally appropriate for describing other genera of Araceae and plants of many other families.

1979 2(1) 28-29 Michael Madison Aroid profile no. 3: Anthurium superbum
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: Anthurium superbum Madison, Selbyana 5:94 (1978). Anthurium superbum is native to seasonally inundated forest along the Rio Napo in Ecuador, where it grows epiphytically above high water level. The dark purple-green bullate leaves held stiffly erect are very striking, and unlike any other anthurium. A large crop of seedlings is now being grown at Selby for distribution to botanical gardens and horticulturists.

1979 2(2) 52-61 Michael Madison Protection of developing seeds in neotropical Araceae (Buy)
ABSTRACT: In flowering plants with animal pollination and seed dispersal the reproductive cycle can be considered to consist of four stages, representing alternating phases of protection and display. In the protective phases immature flowers and fruits are safeguarded from predation and parasitism, while in the display phases pollinators and dispersal vectors are attracted. This alternation of protection and display is accomplished by a variety of mechanisms.

1979 2(3) 67-77 Michael Madison Notes on some aroids along the Rio Negro (Buy)
ABSTRACT: In the fall of 1978 I spent several months collecting plants along the Rio Negro in the western Amazon in connection with the Projecto Flora Amazonas, an ambitious undertaking to prepare a new flora of the Amazon. Although my chief research interests on this expedition were not directed to aroids, I was able to make observations and collections of a number of species.

1979 2(3) 78-81 Thomas B. Croat Germination of seeds of Anthurium (Buy)
ABSTRACT: In my attempts to prepare a systematic revision of Anthurium, I have come to appreciate the value of living plants for study and I have consequently been attempting to assemble a more complete living collection of Anthurium. In addition to being used to prepare more complete and accurate descriptions, the plants are useful for associated studies with cytology, anatomy, floral fragrance chemistry and hybridization studies to determine relationships between species.

1979 2(4) 122-24 Mike Bush Hybridizing anthuriums
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: The genus Anthurium with over 600 species, contains many fine ornamental plants cultivated for their long-lasting and often striking foliage. One of the most rewarding aspects of growing anthuriums is the development of new forms by making hybrids between various species. The procedure for hybridizing anthuriums is relatively simple, and with a little patience and luck highly attractive new forms can be created.

1979 2(4) 126-127 Michael Madison Aroid profile no. 5: Anthurium punctatum
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: Anthurium punctatum N. E. Brown, Gard. Chron. 26:809 (1886). Anthurium puncta tum is native to western Ecuador where it occurs as a pendent epiphyte in tropical wet forest. Like other pendent anthuriums with strap shaped leaves it makes a fine hanging basket plant in cultivation, especially if several shoots are established in a single basket. The plants should be planted in an open, well-drained soil and grown in moderate light.

1980 3(1) 13-18 Mark D. Moffler Qualitative observations on tropical aroid cold tolerance (Buy)
ABSTRACT: As winter approaches each year, we all become concerned about protecting our tropical plants, especially those which are the most susceptible to cold damage. The fall of 1978 was mild in Tampa, with temperatures seldom reaching below 100C (500F). The mild fall gave many of us a false sense of security and steps for cold protection were put off until "tomorrow". It wa~ this unfortunate procrastination that lead to a premature study of cold tolerance in aroids. My initial idea was to test several landscape and porch plants for cold susceptibility, but unfortunately, I unintentionally tested 46 different aroids.

1980 3(2) 39-48 Fred Dortort In the forests of Costa Rica (Buy)
ABSTRACT: Not long ago we had the opportunity to travel in Costa Rica for several weeks. We wanted to observe various tropical plants in their habitats, and we hoped that Costa Rica would be a good choice for our project. Aroids were one of the main groups we were looking for, and we found a large number of them.

1980 3(2) 58-60 Michael Madison Aroid profile no. 6: Anthurium andreanum
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: Anthurium andreanum Linden, III Hort. 24:43, t. 271 (1877). Writing of his discovery a year later Andre remarked, 'it is without doubt one of the most beautiful, if not the most beautiful, of all my discoveries in South America,' (Ill. Hort. 24:43, 1877). He declined to give a precise locality for the plants in fear that other collectors would set out after them, this probably at the insistence of Linden, who jealously guarded his horticultural monopolies.

1980 3(3) 86-93 Richard C. Sheffer, William L. Theobald, Haruyuki Kamemoto Taxonomy of Anthurium scandens (Araceae) (Buy)
ABSTRACT: Anthurium scandens (Aublet) Engler is the most common and widely distributed of all Anthurium species ranging throughout the West Indies and tropical Central and South America. The habit is generally a small, vining, inconspicuous, usually epiphytic aroid. Specimens are occasionally cultivated for their attractive fruits which are sometimes eaten. In the past, the strong and flexible stems were used for making baskets and for tying together the framework of huts (Standley, 1937).

1981 4(2) 54-56 Mark D. Moffler Anthurium araliifolium
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: I obtained A. araliifolium from the Marie Selby Botanical Gardens in 1978 (Fig. 1, a.,b.). Since this Anthurium is seldom encountered in collections and certainly has horticultural merit (at least for aroid collectors), my thoughts turned to propagation. When I obtained A. araliifolium, three spadices were developing and I decided to self pollinate the flowers in order to have many seeds of this fine plant.

1981 4(3) 77-86 Haruyuki Kamemoto Anthurium breeding in Hawaii (Buy)
ABSTRACT: Anthurium andraeanum Linden ex Andre was introduced into Hawaii from London by S. M. Damon in 1889. The spathe color of the first introduction was shellpink. Plants were cultivated in the Damon Estate in Moanalua, Oahu, and by the 1930's had been distributed to other estates, nurseries and hobbyists. Dissemination up to that time was relatively slow due to the inherently slow rate of vegetative propagation of anthuriums. In the late 1930's and 1940's growers had learned to propagate anthuriums from seeds. This resulted in the widespread cultivation of this species and its variants in Hawaii. The novel, exotic, attractive and long-lasting anthurium inflorescences began to appear with regularity in local flower shops.

1981 4(3) 91-92 Thomas B. Croat Propagation of Anthurium cuttings
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: Recent improvement in the success of propagation techniques employed for general aroid collections prompts me to pass on the information to other members. Though I was not trained as a horticulturist, my trial and error procedures in the establishment of thousands of newly introduced aroids over the course of several years has of necessity educated me. Although I am still not satisfied with my loss rate, there has been so much improvement that I feel compelled to pass on this information in hopes of inducing others to report on successful propagation techniques.

This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: With the increasing diversity of Anthurium species now being found in collections, it is not surprising that hybrid plants are appearing more frequently than in the past. Aside from the taxonomic problems these hybrids may pose, or answer, they do provide growers with challenging opportunities. Can you imagine a bird's nest type Anthurium with leaf veins like those of Anthurium crystallinum? How would you like an Anthurium hybrid with leaves shaped like those of Anthurium pedatum but with the coloring of Anthurium clarinervum? Plant breeding must be a special province of optimism. I would like to introduce you to a couple of optimistic growers.

1982 5(2) 37-46 Thomas B. Croat Aroid collecting in western South America (Buy)
ABSTRACT: I set off on my trip to western South America. I began in Ecuador and continued through Peru and returned by way of Colombia. In all, nearly two thousand aroids were collected and sent back alive. Herbarium specimens, notes and photographs were accumulated as well. My principal objective on the three month trip was to locate as many members of the bird's-nest Anthurium group as possible. Thus the search for this group (technically, section Pachyneurium) set the basic itinerary of the trip.

1982 5(2) 47-59 Michael H. Grayum The aroid flora of Finca La Selva (Buy)
ABSTRACT: Costa Rica is a small Central American nation about the size of Denmark, with a remakable array of climatic regimes, and altitudes ranging from sea level to nearly four thousand meters. One can ascend from semidesert scrub forests on the Pacific slope, up through sodden cloud forests to pa'ramo (a kind of a high altitude chaparral) on the highest peaks, and down again on the Caribbean slope, through alders, elms and oaks, to humid lowlands and rain forests. The plants growing in this multifaceted domain are incredibly diverse, even by tropical standards. Costa Rica boasts nearly twenty-five percent more species of dicots, for example, than the lush tropical isle of Java, and nearly two and a half times as many species of dicot epiphytes (Burger, 1980) - this despite the fact that Java is two and a half times larger than Costa Rica and has yielded fifty percent more herbarium specimens per unit area (Prance., 1978).

1982 5(3) 67-88 Dan H. Nicholson Translation of Engler's classification of Araceae with updating (Buy)
ABSTRACT: When Hooker (1883) was preparing the treatment of Araceae (Aroideae) for the monumental 'Genera Plantarum,' he basically followed the Schottian system, incorporating Engler's (1879) reduction in the number of genera. The first system was "popularized" by Hutchinson (1959) who, with a reversal of the sequence (bisexual genera first), published essentially an English translation of Hooker's latin. Engler (1905-1920), in his monumental 'Das Pflanzenreich', produced his final treatment of the family, including all then known species in nine volumes. This work remains the standard reference for the family as a whole.

1982 5(4) 103-107 David Burnett The problems of names for Araceae: A proposal for hybrid and cultivars (Buy)
ABSTRACT: There are internationally accepted rules for naming plants at all of these levels. Further there are rules for naming hybrids between Genera (there are probably no known intergeneric hybrids in Araceae): Hybrids between species and hybrids between cultivars. Generally species hybrids are to be named by a formula (and, if appropriate, a name) and hybrids between cultivars by a name along the lines of cultivars. What I propose in this article is that we must depart, slightly, from the rules of the Code. What I regard as two slight departures may seem, to some, as major. This is a matter for the members to decide.

1983 6(4) 132-134 Thomas B. Croat The origin of Anthurium leuconeurum
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: The name Anthurium leuconeurum has been in use by horticulturists since 1862 when a plant, believed to have been collected in southern Mexico by Auguste Boniface Ghiesbrecht, was described by the French botanist Charles Lemaire. The plant apparently flourished in European botanical garden hothouse collections for a period of about seven decades. A number of herbarium collections were prepared and placed in herbaria at Kew Gardens, Geneva, Paris and elsewhere; most of these collections were made before 1895. The last such herbarium collection I've seen was prepared in 1935 at the University of Coimbra, Portugal, by L. W. Carrisso and deposited at the Kew Herbarium.

1988 11(2) 7-14 Mari Marutani, Surawit Wannakrairoj, Haruyuki Kamemoto Chromosome studies on Anthurium amnicola and its hybrids (Buy)
ABSTRACT: Anthurium amnicola has a somatic chromosome number of 30, the most common number in the genus. There are two pairs of large metacentric chromosomes, three pairs of fairly large acrocentric chromosomes, one pair of satellite chromosomes, and nine pairs of either metacentric or acrocentric small chromosomes. At prometaphase I of meiosis in pollen mother cells 15 bivalents were formed. A. amnicola hybridized readily with A. andraeanum, A. lindenianum, and A. formosum in the section Calomystrium as well as the cultivars 'Calypso' and 'Trinidad' of unknown origin. All interspecific hybrids examined meiotically formed 15 pairs, and all except two hybrids with A. lindenianum showed more than 90% normal tetrad formation. Pollen stainability of these hybrids with acetocarmine ranged from 3.3% to 27.8%, compared to 87.5% in A. amnicola. It is concluded that A. amnicola is genetically closely related to species in section Calomystrium.

1988 11(3) 4-55 Thomas B. Croat Ecology and life forms of Araceae (Buy Back Issue)
ABSTRACT: The most interesting aspect of the family's ecology is the diversity of adaptive life forms. These range from submerged to free-floating, and emergent aquatics to terrestrial plants and to epilithic or epiphytic forms which may be true epiphytes or hemiepiphytic (growing on trees but rooted in soil). Hemiepiphytism is diverse itself, with some species beginning their lives as terrestrial seedlings, then growing skototropically (toward darkness) until they arrive at the nearest suitable tree ( usually a relatively large one which casts a darker shadow) where a physiological change takes place allowing them to grow toward light (Strong & Ray, 1975). They grow as appressed epiphytes on trees or as vines in the canopy. Others begin their lives as true epiphytes, some reconverting to hemiepiphytes by producing long, dangling roots contacting the forest floor below.

1997 20 29-36 Adelheid R. Kuehnle Progress in protoplast Isolation and culture from axenic tissues of hybrid Anthurium (Buy)
ABSTRACT: Protoplasts capable of first divisions were isolated from Anthurium andraeanum Linden ex Andre hybrids using axenic etiolated shoots of the University of Hawaii Antburium cultivars 'Rudolph', UH1060, and UH1003. Enzymatic digestion by 1.5% (w/v) Cellulase R-lO, 0.5% Macerozyme R-10 and 0.5% Driselase in 0.5 M mannitol gave consistent yields between 1.6 X 104 to 2.2 X 104 protoplasts per gram fresh weight of etiolated shoots. In contrast, similar digestions using green leaves of micropropagated plantlets always resulted in mixtures of protoplasts and partially digested cells in ratios of about 1:1 to 1:3, respectively, with a mean yield of 3.8 X 105 protoplasts per gram fresh weight of leaves. Etiolated shoots exposed to a 14-day low light treatment gave consistently higher yields than those with no light exposure, with 3.8 X 104 and 1.8 X 104 protoplasts per gram fresh weight, respectively. Anthurium 'Rudolph' and UH1060 protoplasts were cultured in darkness at densities ranging from 2.5 X 104 to 7.0 X 104 protoplasts ml- ' in a basic tobacco protoplast culture medium with 1 mg' liter-l 6-benzylaminopurine, 1 mgÂ·liter-' IX-naphthaleneacetic acid, and 0.1 mgÂ·liter-' 2,4-dichlorophenoxyacetic acid either in liquid or embedded in 0.6% agarose. Antburium etiolated shoot protoplasts divided within 2 to 6 days and some sustained divisions to form microcolonies within 10 days under these conditions.

1998 21 26-145 Thomas B. Croat History and current status of systemic research with Araceae (Buy Back Issue)
ABSTRACT: This paper will cover all systematic and floristic work that deals with Araceae which is known to me. It will not, in general, deal with agronomic papers on Araceae such as the rich literature on taro and its cultivation, nor will it deal with smaller papers of a technical nature or those dealing with pollination biology. It will include review papers on technical subjects and all works, regardless of their nature, of current aroid researchers. It is hoped that other reviews will be forthcoming which will cover separately the technical papers dealing with anatomy, cytology, physiology, palenology, and other similar areas and that still another review will be published on the subject of pollination biology of Araceae and the rich literature dealing with thermogenesis.

1999 22 48-61 Nuttha Kuanprasert, Adelheid R. Kuehnle Fragrance quality (Buy)
ABSTRACT: A total of 146 Anthurium species and hybrids from sections Belolonchium, Calomystrium, Cardiolonchium, Chamaerepium, Dactylophyllum, Leptanthurium, Oxycarpium, Pachyneurium, Porphyrochitonium, Semaeophyllium, Tetraspermium and Urospadix was evaluated for floral fragrance. Type of fragrance, time of emission, daily occurrence and developmental stage of scent emission were recorded along with the color of spathe and spadix and the environmental conditions. A majority of plants emitted scent: 68% of the species and 80% of the hybrids were fragrant. Fragrance was categorized as citrus, fishy, floral, foul, fruity, menthol, minty, pine, spicy, and sweet. There was no correlation between scent production or quality with flower color or botanical section. A plurality of plants emitted scent during the morning only (45%) and at the pistillate stage (77%). Detection of fragrance depended upon ambient temperature and relative humidity. Fragrance life of unharvested inflorescences varied from 3 days up to 4 weeks, whereas that of harvested inflorescences was short, only 1 or 2 days. First generation progeny analyses from 22 crosses between non-fragrant and fragrant parents indicated that multiple genes likely govern the presence of scent in Anthurium.

2000 23 26-30 Thomas B. Croat, M. A. PÃ©rez-Farrera A new record of Anthurium sarukhanianum (Araceae) to Chiapas (Buy)
ABSTRACT: Antburium sarukhanianum Croat & Haager is recorded for Chiapas, Mexico. It is most closely related to A. balmoorei from west central Mexico but is similar to A. schlechtendalii. It differs from the former principally in the shape of its spadix and the petiole cross-sectional shape. It differs from A. scblecbtendalii by the shape of the spadix and spathe, by berry color and by the shape of the petiole and apex of blade. The record of A. sarukbanianum in Chiapas constitutes a considerable range extension from the only site previously known in the state of Guerrero in west central Mexico. Fruit color is reported for the A. sarukbanianum for the first time. The species produces yellow-orange berries similar to the yellow berries of A. balmoorei; another species in section Pacbyneurium from western Mexico.

2000 23 56-81 C.M. Sakuragui Araceae of campos (Buy)
ABSTRACT: The campo rupestre vegetation is a montane, predominantly herbaceous plant formation that occurs mostly above 800 m. The Araceae, a family with greatest diversity in humid tropical forest habitats, has relatively few species in the Brazilian campos rupestres. However after an intensive fieldwork program a high proportion of species present were found to be new and endemic to the region. In the study ten species were recognized, one (Anthurium montezumense) being new to science. The species recognized are: Anthurium affine, Anthurium minarum, Anthurium montezumense, Anthurium mourae, Philodendron aeutatum, Philodendron adamantinum, Philodendron biribirense, Philodendron cipoense, Philodendron rhizomatosum and Philodendron uliginosum. The work has resulted in the production of keys to the genera and species, descriptions and commentary variously for the species.

2003 26 120-124 J. Ehrenberger, Adelheid R. Kuehnle Enhanced histological technique for observation of spathe pigmentation in Anthurium species and hybrids (Buy)
ABSTRACT: A total of 12 Anthurium species and hybrids were examined histologically for pigmentation in spathes using a new method employing vacuum infiltration of spathe tissue with polyethylene glycol (PEG) priorto cross-sectioning. PEG infiltration displaces intercellular air spaces between cells. This method greatly improved the clarity of the cross sections and consequently improved observations of spatial localization of anthocyanins and chloroplasts.

2007 30 23-37 Thomas B. Croat, Jane Whitehill, Emily D. Yates A new subsection of Anthurium section Calomystrium (Araceae) and five new species from Columbia and Ecuador (Buy)
ABSTRACT: Subsection Rupicola, a new subsection of Anthurium section Calomystrium is proposed, encompassing nine rupicolous species. Descriptions and a key are provided for these species including: A. antrophyoides Killip, from Ecuador and Colombia, A. chocoense Croat and A. antioquiense Engler from Colombia, as well as A. amnicola Dressler, and A. sytsmae Croat from Panama. Five species, A. palacioanum Croat and A. weiffii Croat from Ecuador, and A. chocoense Croat, A. callejasii Croat, and A. vanderknaapii Croat, from Colombia, are described as new. Members of this group were previously thought to belong in section Porphyrochitonium because of their generally lanceolate leaf blades, and stems with short internodes. However, lack of distinct glandular punctations on blade surfaces and the ability to interbreed readily with other members of section Calomystrium indicate that this new group belongs in section Calomystrium, and has evolved without conspicuous posterior lobes typical of section Calomystrium, owing to their rupicolous habitat.
