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.

ABSTRACT: A recent collection by Timothy Plowman and associates made in December 1982 on the Projecto Flora Project under the auspices of the New York Botanical Garden in Brazil has proven to be the rare Alloschemone occidentalis.

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.

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.

2001 24 80-93 Josef Bogner, Peter C. Boyce, C.M. Sakuragui A revision of Alloschemone Schott (Araceae: Monstereae) (Buy)
ABSTRACT: The genus Alloschemone Schott is revised. One new species, A. inopinata Bogner & P. C. Boyce, is recognized, and an expanded description of A. occidentalis (Poepp.) Engl. & K. Krause is presented. The distinguishing characters of the genus are discussed, especially with regard to the genus Scindapsus Schott, from which Alloschemone has been considered inseparable. Both genera have unilocular ovaries with basal placentation with one ovule; Alloschemone differs from Scindapsus by a pinnatifid leaf lamina (entire in Scindapsus), shoot architecture, anatomical differences, and Neotropical distribution (Scindapsus Paleotropical). Our new species has fused filaments, a unique character in Monstereae, and further differs from A. occidentalis by the narrower leaf pinnate separated by an oblong sinus. Seeds, often diagnostically very useful in Monstereae, are still unknown in Alloschemone and are highly desirable.

ABSTRACT: Images intended to accompany an earlier publication of this species (Bogner, Boyce & Sakuragui, 2001) were lost. Additional material has now been received and images are published here.
