1978 1(1) 3 Michael Madison Introductory remarks
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: The family Araceae includes some 2000 species of perennial herbs mostly native to wet tropical areas, but also represented in temperate and semi-arid regions. The family is not especially closely related to any other plant family, but evidently diverged from the other flowering plants at an early stage and has had a long and independent evolution.

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) 13 Michael Madison Philodendron frits-wentii rediscovered

ABSTRACT: Recently Timothy Plowman of Harvard University and Helen Kennedy of the Field Museum discovered Philodendron frits-wentii in the wild in Peru, and sent cuttings to the Marie Selby Botanical Gardens where it is now cultivated. The exact locality, in the Dept. of San Martin, is about 500 km from the nearest known station for P. grazielae.

1978 1(1) 14-16 Michael Madison Aroid profile no. 1: Monstera deliciosa
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: It is appropriate that the first of this series of aroid profiles should depict what is probably the finest foliage plant ever introduced into horticulture - Monstera deliciosa. Well known as a house plant in temperate regions, the species is at its most magnificent out of doors as a rambling vine or climber in tropical localities. Under the best circumstances the leaves are a meter in length with a thick glossy texture and more than a hundred of their characteristic perforations.

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) 26 Michael Madison Aroid literature: The Aroids of Mexico
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: Bunting. G.S. 1965. Commentary on Mexican Araceae. Gentes Herbarum 9:290-382. Matuda, E. 1954. Las Araceas Mexicanas. An. lnst. BioI. 25:97-218. These two works are the basic references on the aroid flora of Mexico, which includes close to a hundred species mostly native to the humid gulf coast and southwestern parts of the country. A number of the species are fine ornamentals well-known in cultivation

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.

1978 1(2) 58-59 Michael Madison Potting media for epiphytic aroids
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: A well-known principle of horticulture is that to grow a plant well you should try to duplicate as closely as possible the conditions under which it thrives in the wild. Since the family Araceae encompasses genera and species from widely varying habitats, including epiphytes, terrestrials, aquatics, and vines, it is evident that no single potting medium will serve equally well for all of the species. Nonetheless, a good number of the aroids in cultivation are epiphytes which have roughly similar requirements and can be grown in a standard soil mix.

1978 1(3) 74-76 Michael Madison The aroid collections at the Marie Selby Botanical Gardens
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: The collection of living aroids at Selby, still actively increasing, at present includes over 1100 collections representing about 600 species in 44 genera. Nearly all are wildcollected plants with carefully kept records of their place of origin, identifiable from an accession number embossed in an aluminum tag 74 attached to each plant. The best represented genera are Anthurium (400+ collections), Philodendron (166 collections) and Caladium (28 collections). The bulk of the collection has been assembled by three of the Gardens' staff members: Dr. Calaway H. Dodson, DIrector; Dr. M. T. Madison, Curator, and Dr. Timothy Plowman, Adjunct Taxonomist. Since these three have research interests centered in the northern Andes, it is not surprising that plants from Ecuador, Colombia, and Peru predominate in the collection. The representation of Asian aroids is much weaker, and from Africa and Australia there is hardly anything at all.

1978 1(3) 86-87 Michael Madison Aroid profile no. 2: Anthurium lilacinum

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) 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(2) 62-63 Michael Madison Aroid profile no. 4: Xenophya lauterbachiana

ABSTRACT: Xenophya lauterbachiana (Engler)Nicolson, Blumea 16:117 (1968) Synonyms: Schizocasia lauterbachiana Engler Alocasia wavriniana Mast. Reference: Nicolson, D.H., 1968. The Genus Xenophya Schott (Araceae), Blumea 16:115-118. in primary lowland rainforest to elevations of 700m in northeastern New Guinea. The species was introduced into cultivation by Micholitz in the 1890's, and has been sparingly cultivated ever since, though it is a handsome plant that ought to be more widely grown.

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(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(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.

1981 4(2) 68-69 Michael Madison Packing and shipping aroids
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: With modem air travel reducing shipping time to a day or two, the success rate of transporting aroids is much improved, but many plants are still killed by improper shipping. The problems mostly have to do with correct preparation and packaging.
