Download or read book A Study of the Genus Schistocarpha (Heliantheae written by Harold Robinson and published by . This book was released on 1979 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Schistocarpha is placed in the subtribe Galinsoginae near Oteiza and is not considered closely related to Neurolaena of the subtribe Neurolaeninae. Sixteen species are recognized, including four newly described; S. chiapensis and S. matudae of Mexico, S. pseudoseleri of Guatemala, and S. wilburii of Costa Rica. A progression is noted in the genus with more northern species having less than 20 ray flowers per head and more southern groups having more than 20. The widely distributed S. eupatorioides, which represents the extreme in the series with 40-70 rays, is regarded as South American in origin. The South American S. sinforosii is regarded as Central American in origin.

Download or read book A Systematic Study of the Subtribe Espeletiinae (Heliantheae, Asteraceae) written by José Cuatrecasas and published by New York Botanical Garden PressDept. This book was released on 2013 with total page 689 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1932, José Cuatrecasas made his first visit to the high-altitude zones of the northern Andes in South America. He was struck by the rich and complex vegetation of the páramos of Colombia; in particular, the bizarre life-form of Espeletia gave him "the impression of being confronted with a different world." At the time of his death in 1996 at the age of 93, Cuatrecasas had nearly completed his ambitious taxonomic revision of this fascinating group of plants. Seven genera of subtribe Espeletiinae are included here: Espeletia, Carramboa, Tamania, Libanothamnus, Ruilopezia, Coespeletia, and Paramiflos. (The eighth and final genus, Espeletiopsis, was summarized briefly in a separate paper in 1996.) The 269 botanical illustrations, 60 micrographs, and 190 monochrome photographs provide a wealth of historical, ecological, phytogeographical, anatomical, and cytological information -- P. 4 of cover.

Available in PDF, EPUB and Kindle. Book excerpt: T. J. MABRY and G. W AGENITZ The half-day symposium on "Multidisciplinary approaches to the systematics of Compositae", held as part of the XIV International Botanical Congress in Berlin, on July 26, 1987, was designed to complement the University of Reading Compositae Conference (1975). The latter had yielded two impressive and thorough volumes on "The biology and chemistry of the Compositae", which were edited by HEYWOOD, HARBORNE & TURNER (1977). The 1987 Berlin Symposium did not attempt to update the information from the earlier conference but instead focussed on selected new methods for investigating the systematics of the family as well as a few examples of new systematic approaches with classical methods. From mapping chloroplast DNA restriction sites JANSEN, PALMER, and MI CHAELS reported the astonishing fact that, with the exception of one group (the subtribe Barnadesiinae of the tribe Mutisieae), all investigated other members of Compositae exhibit a characteristic inversion in their chloroplast DNA, suggesting that the inversion occurred early in the evolution of the family and that at least its major part is monophyletic. Within those groups with the inverted segment, chloroplast DNA also suggests that most of the conventionally recognized tribes are also monophyletic. This lends high credit to our predecessors who laid the foundations for the taxonomic system of the Compositae. These chloroplast DNA studies have already been published and are not included here (JANSEN & PALMER 1987, 1988).

Download or read book A Revision of the Tribal and Subtribal Limits of the Heliantheae (Asteraceae) written by Harold Ernest Robinson and published by . 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.

Download or read book Vascular Plants of Texas written by Stanley D. Jones and published by University of Texas Press. This book was released on 2014-09-11 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Everyone with a professional interest in the flora of Texas will welcome this checklist of the vascular plants. This comprehensive list also includes crops, persistent perennials, and naturalized plants and encompasses over 1,000 changes to the previous (Hatch, 1990) checklist. The authors have arranged this checklist phylogenetically by classes following the Cronquist system. Several features make this checklist especially useful. Chief among them is the relative synonymy (name history). An extensive index makes current classification and correct nomenclature readily accessible, while the botanical bibliography is the most extensive ever compiled for Texas. The authors also note which plants have been listed as threatened or endangered by the Texas Organization of Endangered Species, which are designated as Federal Noxious Weeds, and which have been chosen as state tree, flower, fruit, etc. by the Texas Legislature.

Available in PDF, EPUB and Kindle. Book excerpt: The presence of brush in rangeland environments continually tops the list of priority issues among landowners, and not just in Texas. Whether they manage their land for livestock, hunting, or wildlife watching, what to do about unwanted woody plants remains a serious and pervasive question for landowners everywhere. In the pages of this book, leading range management professionals introduce and explain not only the mechanisms of managing brush but also the changes in management philosophy and technology that have taken place over time. From the futile attempts at eradication to the successes of integrated brush management, expert practitioners examine mechanical, biological, chemical, and fire-related methods from three perspectives—the past, the present or “state-of-the-art,” and the future. In a final discussion, three specialists address the timely and important subject of brush management as it relates to water yield, economics, and wildlife. Brush Management: Past, Present, Future gives readers a straightforward and comprehensive view of a topic that remains a consistent concern for livestock, wildlife, and land management—one that will serve as a useful and interesting summary of the subject for teachers, students, landowners, and management professionals.
