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.

 ABSTRACT: Theriophonum fischeri Sivadasan, sp. nov. is described.
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.
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: 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.

M. Sivadasan, M. Wilson Morphology and floral vasculature of Theriophonum infaustum N. E. Br. (Araceae) (Buy)
 ABSTRACT: Theriophonum infaustum N.E. Br. (Araceae) is monoecious with unisexual flowers. The female flowers are with unilocular ovaries having basal and apical suborthotropous ovules. The present study of the floral vascular organization revealed that the ovary is tricarpellate syncarpous, but unilocular and hence pseudomonomerous. The basal and apical placentae are truly basal-parietal and apical-parietal, and they originated by the elimination of septa and ovules along the central region. Vascular organization in the female flowers was found to be diverse, having fused and independent lateral bundles of corresponding carpels of the tricarpellate syncarpous unilocular gynoecium. The male flowers were supplied with single unbranched staminal bundles and this is a derived condition from the primitive multiple- traced condition. The neuter flowers were also supplied with single bundles resembling that of staminal bundles. The sterile spadix appendix was presumed to have formed by the fusion of aborted staminate flowers as evidenced by the lateral bundles produced at the lower half of the appendix.
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.
C. Sathish Kumar, R. Kavalan Flowering phenology and beetle pollination in Theriophonum infaustum N.E. Br. (Araceae) (Buy)
 ABSTRACT: Theriophonum infaustum N.E.Br. (Araceae), an endemic species of SW India, consists of small tuberous plants. The species was found to have protogynous inflorescences and to be visited by several kinds of beetles. Beetles belonging to the species Anotylus rubidus Cameron (Coleoptera, Staphylinidae) are found to be the main potential pollinators. Other species observed were only casual visitors. A detailed account on the process of cantharophily in this species is given with explanatory illustrations.
