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(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.

ABSTRACT: An overview of the chromosome numbers of the genera of Araceae is given.

2005 28 37-42 A. Quilichini, Aurelia Torre, Marc Gibernau Preliminary data on the biology and reproduction of Ambrosina bassii L. (Araceae) in Corsica (Buy)
ABSTRACT: This study explores the floral biology and reproduction mode of Ambrosina bassii L. that belongs to a monospecific genus of the subfamily Aroideae (Araceae). The species has a limited distribution and the number of mature plants within natural populations is low. Reproductive success of this species is limited due to low fructification and seed rates, however there is a positive relationship between the plant vigour and its investment to the reproduction. In stable habitats, there are more flowering plants than in newly colonized habitats, where the frequency of juvenile non-mature plants is higher. The knowledge of these biological and reproductive characters constitutes the first data useful for the preservation and the management of this rare, endangered and protected species on Corsica.
