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.

1985 8(2) 55-63 Josef Bogner Jasarum steyermarkii Bunting (Buy)
ABSTRACT: Jasarum steyermarkii was first discovered by S. and C. Tillett in the Mazaruni River Basin in Guyana on September 24, 1960, but their specimens, although very striking, long remained unidentified. In February 1972, Julian A. Steyermark found the same species in the Estado Bolivar in Venezuela; this collection became the type of the new genus and species, which George S. Bunting published in 1977. The aquatic nature of this aroid is very remarkable because no true aquatic were previously known for the subfamily Colocasioideae. It was certainly one of the most interesting discoveries in Araceae in recent decades.

1986 9(1) 3-213 Thomas B. Croat, Nancy Lambert The Araceae of Venezuela (Buy Back Issue)
ABSTRACT: An illustrated treatment of 171 Venezuelan Araceae taxa is provided. Discussion of range, species characteristics and distinction from similar or closely related species is made for each taxon. Sixteen species, three subspecies and one variety are described as new, and three new combinations are made.

1987 10(2) 4-16 Josef Bogner Morphological variation in aroids (Buy)
ABSTRACT: The Araceae or aroid., are a large family of about 2400 species, grouped in 107 genera and these again in nine subfamilies. The aroids are mainly a tropical family and are distributed world-wide. They show great variation in their morphological characters, which will be described in this paper along with some other data.

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

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.
