Download or read book Revision of Pearcea Gesneriaceae written by Lars Peter Kvist and published by . This book was released on 1996 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seventeen species of Pearcea (Gesneriaceae) are recognized, nine of which are new: Pearcea bella, P. bilabiata, P. cordata, P. fuscicalyx, P. glabrata, P. gracilis, P. grandifolia, P. intermedia, and P. strigosa. Of the remaining eight species, two were originally described in Pearcea, one is transferred herein from Kohleria, and five come from Parakohleria, a genus placed in synonymy herein. Pearcea occurs mainly on the eastern Andean slopes of Colombia (5 species), Ecuador (12 species), Peru (6 species), and Bolivia (1 species), and one species also occurs on the western Andean slopes in Ecuador. The largest number of species appears to occur in Ecuador, although additional species may occur in less explored parts of Peru. Pearcea differs from related and similar genera in the Gloxinieae by having fleshy capsules dehiscing by two valves and exposing a sticky seed mass. All species are herbs, usually with bright red flowers, and are usually found in the shady, humid forest understory, often near small streams. Hybridization, local speciation, and polymorphic variation may complicate the species delimitation. The variable Pearcea sprucei occurs throughout nearly the entire range of the genus (and includes the only accepted variety, var. parviflora), but most species are rare and local.

Download or read book Systematics Evolution and Biogeography of Compositae written by Vicki Ann Funk and published by . This book was released on 2009 with total page 1008 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This spectacular book does full justice to the Compositae (Asteraceae), the largest and most successful flowering plant family with some 1700 genera and 24,000 species. It is an indispensable reference, providing the most up-to-date hypotheses of phylogenetic relationships in the family based on molecular and morphological characters, along with the corresponding subfamilial and tribal classification. The 2009 work not only integrates the extensive molecular phylogenetic analyses conducted in the last 25 years, but also uses these to produce a metatree for about 900 taxa of Compositae. The book contains 44 chapters, contributed by 80 authors, covering the history, economic importance, character variation, and systematic and phylogenetic diversity of the family. The emphasis of this work is phylogenetic; its chapters provide a detailed, current, and thoroughly documented presentation of the major (and not so major) clades in the family, citing some 2632 references. Like the Compositae, the book is massive, diverse, and fascinating. It is beautifully illustrated, with 170 figures, and an additional 108 cladograms (all consistently color-coded, based on the geographic range of the included taxa); within these figures are displayed 443 color photographs, clearly demonstrating the amazing array of floral and vegetative form expressed by members of the clade." --NHBS Environment Bookstore.

This book was released on 1981 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tribe Heliantheae is expanded to include the genera previously placed in the tribe Helenieae and many genera from the Senecioneae. Thirty-five subtribes are recognized and described, and the more than 265 genera are listed with known, validly described synonyms. A theoretical key to subtribes is provided. Various structural and chemical characteristics are reviewed, and emphasis is given to resin duct patterns, presence of fiber-sheaths in disk corollas, and patterns of striations in achenes. The Heliantheae is considered a member of the subfamily Asteroideae in a position parallel to and more advanced than the Eupatorieae.
