Available in PDF, EPUB and Kindle. Book excerpt: Ce livre historique peut contenir de nombreuses coquilles et du texte manquant. Les acheteurs peuvent generalement telecharger une copie gratuite scannee du livre original (sans les coquilles) aupres de l'editeur. Non reference. Non illustre. 1914 edition. Extrait: ...To be removed to genus Onuris. Add Macl., p. 447, after line 4: SARCODRABA Gilg & Muschler. Close to Draba, but easily separable through its turgid silicles; the midnerve of its valves strongly developed; and its fleshy leaves suffruticose; stem woody, thick, branching, sending up many floriferous stalks, leafy at top. Leaves crowded at base, above distant, thick, and rather large, serrate, incised. Flowers somewhat large, crowded in a dense raceme. Nectariferous glands form a ring. Fruits oblong, attenuate below, apically clinging to a cylindric style. Stigma cushion-like, bilobed, valves very convex, hard, with a raised median nerve, and thick placentiferous margins. S. Karraikensis (Speg.) Gilg & Muschler. Syn. Draba karraikensis Speg. Description p. 445, no. 13. In South Patagonia, central part of the territory of Sta. Cruz; by Rio Sta. Cruz on saline sandy clay; by Rio Leona (between Lago Argentino and Lago Viedma); and on saline sandy clay in the low mountains. A very variable species, divided by Spegazzini into three varieties, which, according to Gilg and Muschler, are rather to be considered as only forms, magna, media, minima; in fruit January. D. Add Macl., p. 447: ONURIS Phil. Crucifers, near Draba, like a small form of Hutchinsia; but the septum is as in Draba. The opening of the strong-nerved valves and the short, not-lobed style, separate it from Draba. Found in the mountains of S. Amer. Perennial herbs with thick, many-headed rhizome, and branches bearing many very dense heads of leaves, which are grass-like. Flowers white, in racemes, on a naked, scape-like peduncle; bracts linear, usually with the lower flowers. Nectariferous glands form a ring. Fruit ovate or narrower, ..."
Download or read book Guide to Standard Floras of the World written by David G. Frodin and published by Cambridge University Press. This book was released on 2001-06-14 with total page 1136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 2001 book provides a selective annotated bibliography of the principal floras and related works of inventory for vascular plants. The second edition was completely updated and expanded to take into account the substantial literature of the late twentieth century, and features a more fully developed review of the history of floristic documentation. The works covered are principally specialist publications such as floras, checklists, distribution atlases, systematic iconographies and enumerations or catalogues, although a relatively few more popularly oriented books are also included. The Guide is organised in ten geographical divisions, with these successively divided into regions and units, each of which is prefaced with a historical review of floristic studies. In addition to the bibliography, the book includes general chapters on botanical bibliography, the history of floras, and general principles and current trends, plus an appendix on bibliographic searching, a lexicon of serial abbreviations, and author and geographical indexes.

Download or read book Ice Age Southern Andes written by C.J. Heusser and published by Elsevier. This book was released on 2003-11-12 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Southern Andes, stretching from the subtropics to the subantarctic, are ideally located for palaeoenvironmental research. Over the broad and continuous latitudinal extent of the cordillera (-24˚), vegetation is adjusted to climatic gradients and atmospheric circulation patterns.Opposed to the prevailing Southern Westerlies, the Southern Andes are positioned to receive the brunt of the winds, while biota are set to record the shifting of incoming storm systems over time. Sequential, latitudinally-placed, sedimentary deposits containing microfossils and macroremains, as archives of past vegetation and climate, make possible the detection of equatorward and poleward displacement of plant communities and, as a consequence, changes in climatic controls. No terrestrial setting in the Southern Hemisphere is so unique for palaeoenvironmental reconstruction during and since the last ice age. Twenty radiocarbon-dated fossil pollen and spore records chosen to place emphasis on the last ice age include high-resolution, submillennial data sets that also cover the Holocene, thus providing contrast between present interglacial and past glacial ages. From a refined data base, the records constitute the foundation for interpreting factors responsible for vegetation change over >50,000 14C years, glacial-interglacial migration and refugial patterns for a diversity of taxa, and the extent of intrahemispheric and polar hemispheric synchroneity versus asynchroneity.

Download or read book Early Miocene Paleobiology in Patagonia written by Sergio F. Vizcaíno and published by Cambridge University Press. This book was released on 2012-10-11 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal exposures of the Santa Cruz Formation in southern Patagonia have been a fertile ground for recovery of Early Miocene vertebrates for more than 100 years. This volume presents a comprehensive compilation of important mammalian groups which continue to thrive today. It includes the most recent fossil finds as well as important new interpretations based on ten years of fieldwork by the authors. A key focus is placed on the paleoclimate and paleoenvironment during the time of deposition in the Middle Miocene Climatic Optimum (MMCO) between twenty and fifteen million years ago. The authors present the first reconstruction of what climatic conditions were like and present important new evidence of the geochronological age, habits and community structures of fossil bird and mammal species. Academic researchers and graduate students in paleontology, paleobiology, paleoecology, stratigraphy, climatology and geochronology will find this a valuable source of information about this fascinating geological formation.

Download or read book Illustrated Moss Flora of Antarctica written by Ryszard Ochyra and published by Cambridge University Press. This book was released on 2008-11-13 with total page 711 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mosses are a major component of the vegetation in ice-free coastal regions of Antarctica. They play an important role in the colonisation of ice-free terrain, accumulation of organic matter, release of organic exudates, and also provide a food and habitat resource for invertebrates. They serve as model organisms for physiological experiments designed to elucidate problems of plant cold tolerance and survival mechanisms and for monitoring biological responses to climate change. This Flora provides the first comprehensive description, with keys, of all known species and varieties of moss in the Antarctic biome. It has involved microscopic examination of around 10,000 specimens from Antarctica and, for comparison, from other continents. All species are illustrated by detailed line drawings, alongside information about their reproductive status, ecology, and distribution. This is an invaluable resource for bryologists worldwide, as well as to Antarctic botanists and other terrestrial biologists.
