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.

1980 3(2) 49-54 Harald Riedl The importance of ecology for generic and specific differentiation in the Araceae-Aroideae (Buy)
ABSTRACT: It is Meusel's (1951) merit to have pointed out the significance of growth-habit for interpreting the evolution of a particular group of plants. In his paper he chose Araceae and Lemnaceae as striking examples to prove his point. While it is rather difficult to translate the German terminology he used for those plants which produce persistent parts above the ground, the term "geophytes" fits well for all those which persist with their subterranean parts alone. Among Araceae, rhizomatous and tuberous geophytes are known. Subfamily Aroideae is composed almost entirely of members of the latter group with the exception of plants growing in water or at least swampy ground, like Lagenandra. While, according to Meusel, intermediates between rhizomatous and tuberous geophytes are found in Colocasioideae, geophytes are rare or absent in the rest of the family.

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(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.

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.

1989 12(1) 6-8 Thomas B. Croat Ecology and life forms of Araceae: A follow-up
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: This paper deals with new information concerning the ecology and life forms of Araceae that has come to light since the publication of "Ecology and Life Forms of Araceae," in Aroideana Volume 11 (3-4). 1988 (990). Also included are corrected errors in that article.

1993 16 37-46 Gitte Peterson Chromosome numbers of the genera Araceae (Buy)
ABSTRACT: An overview of the chromosome numbers of the genera of Araceae is given.

1994 17 33-60 Thomas B. Croat Taxonomic status of neotropical aroids (Buy)
ABSTRACT: While the Paleotropics has more genera than the Neotropics (60 versus 36) the latter area contains roughly twothirds the species of the world's Araceae. Our level of knowledge of the systematics of the neotropical Araceae varies greatly from area to area, owing largely to recent revisionary work or to the interest and area concentrated on by particular workers.

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.

2003 26 22-26 Eduardo G. Gonçalves A new species and two new combinations for the tribe Spathicarpeae (Araceae) (Buy)
ABSTRACT: A new species of Asterostigma (A. reticulatum E.G.Gonc.) from Southern Brazil is described and illustrated. Two new Andean combinations are also presented. Spathantheum intermedium Bogner and Taccarum cardenasianum Bogner are transferred to the genus Gorgonidium as G. intermedium (Bogner) E.G.Gonc. and G. cardenasianum (Bogner) E.G.Gonc. respectively, and the arguments for both recombinations are presented.

2008 31 3-14 Josef Bogner The genus Bognera Mayo and Nicolson (Araceae) (Buy)
ABSTRACT: The genus Bognera Mayo & Nicolson with its single species Bognera recondita (Madison) Mayo & Nicolson, is described and illustrated and its relationships are discussed in detail. Discussions of its history, discovery, distribution, ecology, pollination, etymology and cultivation are given. The genus Bognera is characterized by its creeping rhizome shoot architecture with two cataphylls preceding each foliage leaf, the last one partly enveloping the petiole (a character unique in the family), the essentially parallel-pinnate venation type (philodendroid) but with third order veins in a clearly reticulate pattern, the unconstricted spathe, the stamens of each male flower connate into a synandrium, the female flowers lacking staminodes, the unilocular ovary with a single anatropous ovule on a basal placenta and the inaperturate pollen grains with smooth (psilate) exine.
