Michael Madison The genera of Araceae in the northern Andes (Buy)
 ABSTRACT: The north Andean region, which includes Colombia, Ecuador, and Peru, has perhaps the richest flora in the world and is the center of diversity of the family Araceae. The low to middle elevation wet forests of the area abound with aroids which cover the ground, climb up tree trunks, and as epiphytes adorn the outer branches of the trees. Many of our finest ornamental aroids, including Anthurium andreanum, A. crystallinum, Caladium bicolor, and Philodendron erubescens, are derived from this area. The purpose of this paper is to provide a key and brief descriptions of the genera of Araceae of the northern Andes which should enable anyone to identify to genus aroids from the region. The key is also applicable in Central America, but only partly so in the rest of South America where a number of additional genera, principally of the subfamily Aroideae, are found.
Michael Madison Protection of developing seeds in neotropical Araceae (Buy)
 ABSTRACT: In flowering plants with animal pollination and seed dispersal the reproductive cycle can be considered to consist of four stages, representing alternating phases of protection and display. In the protective phases immature flowers and fruits are safeguarded from predation and parasitism, while in the display phases pollinators and dispersal vectors are attracted. This alternation of protection and display is accomplished by a variety of mechanisms.

Thomas B. Croat Aroid collecting in western South America (Buy)
 ABSTRACT: I set off on my trip to western South America. I began in Ecuador and continued through Peru and returned by way of Colombia. In all, nearly two thousand aroids were collected and sent back alive. Herbarium specimens, notes and photographs were accumulated as well. My principal objective on the three month trip was to locate as many members of the bird's-nest Anthurium group as possible. Thus the search for this group (technically, section Pachyneurium) set the basic itinerary of the trip.

Michael H. Grayum The aroid flora of Finca La Selva (Buy)
 ABSTRACT: Costa Rica is a small Central American nation about the size of Denmark, with a remakable array of climatic regimes, and altitudes ranging from sea level to nearly four thousand meters. One can ascend from semidesert scrub forests on the Pacific slope, up through sodden cloud forests to pa'ramo (a kind of a high altitude chaparral) on the highest peaks, and down again on the Caribbean slope, through alders, elms and oaks, to humid lowlands and rain forests. The plants growing in this multifaceted domain are incredibly diverse, even by tropical standards. Costa Rica boasts nearly twenty-five percent more species of dicots, for example, than the lush tropical isle of Java, and nearly two and a half times as many species of dicot epiphytes (Burger, 1980) - this despite the fact that Java is two and a half times larger than Costa Rica and has yielded fifty percent more herbarium specimens per unit area (Prance., 1978).
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.
David Burnett The problems of names for Araceae: A proposal for hybrid and cultivars (Buy)
 ABSTRACT: There are internationally accepted rules for naming plants at all of these levels. Further there are rules for naming hybrids between Genera (there are probably no known intergeneric hybrids in Araceae): Hybrids between species and hybrids between cultivars. Generally species hybrids are to be named by a formula (and, if appropriate, a name) and hybrids between cultivars by a name along the lines of cultivars. What I propose in this article is that we must depart, slightly, from the rules of the Code. What I regard as two slight departures may seem, to some, as major. This is a matter for the members to decide.

Robert R. White Panama west (Buy)
 ABSTRACT: As Las Cruces lies only a few miles from the border of Panama, the plants found in the adjacent Panamanian highlands are just as much a part of our local flora as are those of Costa Rica. Therein lay the opportunity for two most enjoyable collecting trips to Panama.
Mark D. Moffler A commentary on the anatomy of a neotropical species of Homalomena (Buy)
 ABSTRACT: The striking and varied foliage pattern in aroids is one of the reasons we collect these fascinating plants_ While ' we all appreciate the elegance of aroids, few people have the opportunity to see the structural beauty at the microscopic level. I will briefly discuss several anatomical features of a neotropical species of Homalomena c.f_ peltata.

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).

This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
 ABSTRACT: After the publication of the new species, Homa/omena speariae Bogner et Moffler (Moffler and Bogner, 1984), I (J.B.) pollinated it by hand obtaining fruits with viable seeds. Seeds were sent to Mr. John Banta of the River Haven Nursery, Rt. 2, Box 144, Alva, Florida 33920, in order to introduce this handsome aroid into the trade. Since our publication, plants were planted into a ground bed at the Munich Botanical Garden where they grew much larger than the original container grown specimens.

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.

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.
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.
Eduardo G. Gonçalves New aroid taxa from Brazil (Buy)
 ABSTRACT: Six new taxa of Brazilian Araceae are here described and illustrated (Philodendron nullinervium E.G.Gonc.; Philodendron tenuispadix E.G.Gonc.; Taccarum crassispathum E.G.Gonc.; Xanthosoma acutum E.G.Gonc., Xanthosoma rotundatum E.G.Gonc. and Xanthosoma pulchrum E.G.Gonc.). Along with them, a new name (Philodendron humile E.G.Gonc.) is proposed for Homalomena solimoense G.M.Barroso, since this has proved to be a species of Philodendron, and simply transferring the epithet as a new combination in Philodendron is likely to lead to confusion with the pre-existing name Philodendron solimoesense A.C. Smith.

Josef Bogner The genus Bognera Mayo and Nicolson (Araceae) (Buy)
 ABSTRACT: The genus Bognera Mayo & Nicolson with its single species Bognera recondita (Madison) Mayo & Nicolson, is described and illustrated and its relationships are discussed in detail. Discussions of its history, discovery, distribution, ecology, pollination, etymology and cultivation are given. The genus Bognera is characterized by its creeping rhizome shoot architecture with two cataphylls preceding each foliage leaf, the last one partly enveloping the petiole (a character unique in the family), the essentially parallel-pinnate venation type (philodendroid) but with third order veins in a clearly reticulate pattern, the unconstricted spathe, the stamens of each male flower connate into a synandrium, the female flowers lacking staminodes, the unilocular ovary with a single anatropous ovule on a basal placenta and the inaperturate pollen grains with smooth (psilate) exine.
