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) 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) 13 Michael Madison Philodendron frits-wentii rediscovered
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
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) 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(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(1) 27 Thomas B. Croat Dr. Eizi Matuda
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: The world of aroid lovers mourns the death of Dr. Eizi Matuda, Senior Curator of the Instituto de Biologia at the Universidad Nacional Autonoma de Mexico in Mexico City. Dr. Matuda, a long time expert in Araceae died February 12, in Peru, while on a field trip following the Second Latin American Botanical Congress in Rio de Janeiro.

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) 63-73 Josef Bogner A critical list of the aroid genera (Buy)
ABSTRACT: Engler's system of the aroids, over one hundred years old, is based not only on floral structures, but also uses vegetative and anatomical characters. His system is still viable and no large changes are necessary today. His arrangement shows a natural phylogenetic system and it has been accepted by all serious students of the family (M. R. Birdsey, G. S. Bunting, T. Croat, M. Madison, D. H. Nicolson, M. Hotta (with a few modifications).

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) 77-85 Harald Riedl Heinrich Wilhelm Schott as a developmental morphologist (Buy)
ABSTRACT: Heinrich Wilhelm Schott is well known as the first important monographer of the family of Araceae who also had proposed a great number of generic names still in use in this family. In numerous publications ranging from short notes covering less than one page to magnificently illustrated volumes in quarto and the voluminous Prodromus systematis Aroidearum he contributed more to our knowledge of aroids than any other botanist with perhaps the exception of A. Engler.
