Book Description
The Araceae of temperate North America (Canada and the continental United States) are reviewed, resolving problems involving their systematics, natural history, and ethnobotany. The aroid genus Peltandra and North American Acoraceae are revised. A comprehensive review of North American Araceae is based on direct examination of over 180 populations in the field, and study of almost 12,000 herbarium specimens. Seven aroid genera with a total of nine species are native to temperate North America plus species in ten introduced genera have been documented outside of cultivation. A key to all species is provided, and each species is discussed with illustrated sections on morphology, synonymy, taxonomy, habitat, distribution (mapped), reproductive phenology, conservation status, ethnobotany, distinguishing features, biology, and specimens examined. A comprehensive revision of Peltandra, one of only two aroid genera endemic to temperate North America, is presented, recognizing two extant species (P. sagittifolia (Michaux) Morong and P. virginica (Linnaeus) Schott) and one fossil species (P. complicatum (Lesquereux) S.A. Thompson, new combination). Although recent authors have treated Peltandra as consisting of a single species with two subspecies, this study quantitatively characterizes two distinct extant species, P. sagittifolia and P. virginica, based on characters of the inflorescence, infructescence, and leaf venation. New information on the biology of Peltandra is presented, including controlled pollination experiments involving P. virginica. Pollination is accomplished by adults of a chloropid fly, Elachiptera formosa, which use inflorescences as sites for mating, oviposition, and larval development. Traditional circumscription of the Araceae included the aberrant genus Acorus, placed by recent authors in its own family, the Acoraceae. A revision of the Acoraceae of North America is presented, resolving problems involving the number of species in this region, native status, and correct nomenclature for American taxa. Studies of morphology, pollen stainability, isozymes, nomenclature, and use by Native Americans are consistent with recognition of two species of Acorus in North America, A. calamus Linnaeus, a sterile triploid introduced by European settlers, and A. americanus (Rafinesque) Rafinesque, a native fertile diploid species. Data on essential oil chemistry, phytopathology, and karyology support that conclusion.

Book Description
Flora of North America, Volume 22, is the first of five volumes covering monocots in North America north of Mexico. The volume comprises many groups of acquatic plants and the North American relatives of groups that have their richest number of species in the New World tropics. Included among the treatments are the rush family (Junaceae), which include important indicator species in wetland habitats, the cat-tails (Typhaceae), spiderworts (Commelinaceae), aroids (Araceae), and pondweeds (Potamogetonaceae). Thirty families are included in this volume, representing a diverse range of plant forms - from marine Zosteraceae (eel-grasses) to stately Arecaceae (palms) and the naturalised exotic Zingiberaceae (gingers), Heliconiaceae (heliconias) and Musaceae (bananas).

Book Description
This revision of Aglaonema (ranging from northeastern India through New Guinea) is based on study of over 1500 herbarium specimens in 33 herbaria, supplemented by field studies and over 100 personal collections made in southeastern Asia over a period of 18 months. Much of the literature of the genus is reviewed, particularly on cytology, embryology, and morphology. The taxonomic portion of the text includes keys, synonymies, descriptions, notes on range, habitat, typification as well as discussion of taxonomic and nomenclatural problems. The sections Aglaonema and Chamaecaulon are recognized for the first time. Although 76 binomials have been published for the genus, only 21 are recognized and accepted herein as species. No new species have been recognized.
