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.

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.

This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
 ABSTRACT: In South India, Arisaema is represented by ten species, including six varieties. One species, hitherto known as Arisaema auriculatum Barnes, is quite rare. It is distinguished by having ony a single compound leaf with sessile, radiate leaflets and a slightly bent, irregularly corrugated tip of the sterile appendix.
F. D. Ghani Ornamental and edible aroids of peninsular Malaysia (Buy)
 ABSTRACT: Most aroids are widely distributed in the tropics and subtropics with a few species in temperate regions. The majority occur in the countries of South East Asia, South and Central America, Africa and the West Indies. The family has a total of 110 genera and ca. 2500 species (Croat, 1979), 92% of which are in South East Asia and Central and South America. In Malaysia alone there are 23 native genera and about 120 species (Henderson, 1954).
Dr. Donald C. Huttleston The North American species of Arisaema (Araceae)-"Jack-in-the-Pulpit" (Buy)
 ABSTRACT: The North American "Jacks-in-thePulpits" are so variable as to have caused a great deal of controversy and confusion. Six specific and numerous subspecific epithets have been applied to them. Graduate research at Cornell between 1946 and 1950 and extensive observations since have lead me to the conclusion that there is but one species, Arisaema triphyllum (L.) Schott, with four subspecific populations. Rather widespread hybrid swarms between these populations tend to confuse their separations. A key to the subspecific categories and a discussion of them follows.
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.

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.
Jin Murata Introduction of the plants of Arisaema recently recognized from Japan (Buy)
 ABSTRACT: Japan is a center of diversity for Arisaema where there are recognized more than 30 species out of the total 150 for the whole genus. Most of them are rare taxa with very limited distribution ranges. This paper aims to introduce these new taxa with photographs and short notes. A key to all Japanese taxa is provided as a synopsis.

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.
K. S. Patil, G. B. Dixit Cytological studies in Araceae Part 1 (Buy)
 ABSTRACT: The largely tropical monocot family Araceae, comprising about 105 genera and 3,500 species in the world (Li Heng, 1993), is an apparently natural and easily recognizable group. In Western Ghats of Maharashtra (India), the taxa of AIaceae are thriving well in both plains and hilly regions. The plants belonging to AIaceae are taxonomically interesting, showing varied habitats. The aim of the present work is to obtain chromosome data of as many hitherto unstudied genera as possible. The cytological work of AIaceae is well known. The chromosome numbers have so far been determined for more than 700 species from intraspecific taxa (Petersen, 1989, 1993) belonging to 99 of the 105 genera presently recognized (Bogner & Nicolson, 1991; Hay, 1992; Li Heng & Hay, 1992) _ The present study reports the chromosome numbers of nine species for the first time.
Shrirang R. Yadav, K. S. Patil, M. K. Janarthanam A new species of Arisaema (Araceae) from western Ghats of southern India (Buy)
 ABSTRACT: Our intensive survey of aroids of Western Ghats in the States of Maharashtra, Karnataka, and Goa for the last 10 years has resulted in the discovery of three new species of aroids. Of the three species, Arisaema sabyadrica Yadav, Pati!, and Bachulkar [Willdenowia 23:177-179, 1993.1 and Amorpbopballus konkanensis Hetterscheid, Yadav & Pati! [Blumea 39:289-294, 1994.1 have already been described, and one more new species of Arisaema is described here. Arisaema sivadasanii Yadav, Patil & Janarthanam sp. nov.
Guy Gusman Arisaema lobatum Engl. (Araceae) and its taxonomic position (Buy)
 ABSTRACT: Arisaema lobatum Engl. differs markedly from other species of the section Pedatisecta by stable morphological characters. This indicates that A. lobatum occupies a special position in the section and leads to the creation of the new subsection Lobata.
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.
G. Dieringer, L. Cabrera R. A comparison of size and sexual expression in populations of Arisaema macrospathum Benth. and A. dracontium (L.) Schott (Araceae) (Buy)
 ABSTRACT: The sexual expression or breeding system for tropical populations of Arisaema macrospathum was compared with that of its temperate counterpart, A. dracontium. Although A. macrospathum populations are morphologically very similar to A. dracontium, they differ markedly in sexual expression. Temperate populations of A. dracontium are andromonoecious, while those of A. macrospathum occurring in cloud forest were found to bear only unisexual flowers, staminate or pistillate with monoecious individuals completely lacking. Male plants produced a mean of 42.7 flowers/spadix while females produced a mean of 60.9. For males, number of flowers/ spadix showed a significant, positive relationship with plant size as measured by basal stern diameter, but no relationship was detected for females. Non-flowering and male plants did not differ in size, but were significantly smaller than female plants as is typical for the congeneric A. triphyllum and probably switch gender under similar circumstances also. Considering the entire geographic range, A. dracontium exhibits a gradual decline in plant size, number of flowers/spadix for males, and an increase in the expression of female plants along a north-south gradient. This gradual decline in size would appear to extend into populations of A. macrospathum and suggests a close evolutionary relationship. Differences in sexual expression between the two species may be related to geographical isolation and the presence or absence of competing congeneric species.

 ABSTRACT: In a paper that appeared in a previous issue of Aroideana (Vol. 30), the author (H. Li, 2007) extends the distribution of Arisaema smitinandii - a species originally discovered in S Thailand - to SE Xizang in China, i.e. ca. 2,300 km further to the North. Unfortunately, this conclusion is deduced on the basis of an error: the three herbarium Chinese specimens (H. Sun, Z.K. Zhou & H.Y. Yu ETM 1090, KUN!) identified as A. smitinandii by the author are the same that were used as paratypes of Arisaema tsangpoense ].T. Yin & G. Gusman (J.T. Yin & G. Gusman, 2006).
