Padrões de distribuição geográfica dos táxons brasileiros de Eragrostis (Poaceae, Chloridoideae)

Abstract: -(Patterns of geographic distribution of the Brazilian taxa of Eragrostis (Poaceae, Chloridoideae)). The genus Eragrostis presents 53 taxa in Brazil, being 38 of them native with distinctive patterns of geographic distribution: exclusively tropical, tropical/subtropical (more abundant in the tropical area but extending their occurrence to the Southern region), tropical and subtropical (as abundant in the tropical region as in the subtropical one), exclusively subtropical, and subtropical/tropical (opposed to t… Show more

“…Algunas especies son forrajeras valiosas, especialmente en suelos áridos (Clayton & Renvoize 1986, Nicora & Rúgulo 1987, Watson & Dallwitz 1992, Van den Borre & Watson 1994 o constituyen malezas asociadas a cultivos (Matthei 1995). En Sudamérica se han realizado varios trabajos taxonómicos sobre Eragrostis, la mayoría de ellos regionales (Nicora 1973, 1994, Renvoize 1998, Tovar 1993, Boechat 1981, Boechat & Longhi-Wagner 2000, Hitchcock 1927, Laegaard & Peterson 2001, Peñaloza-Jiménez et al 2002. Para Chile, Marticorena & Quezada (1985), al igual que Nicora (1994,1998), reconocen 10 especies (Tabla I), sin embargo ambos autores sólo coinciden en 6 de ellas (E. attenuata Hitchc., E. curvula (Schrad.)…”

“…The author recognised: a) megathermic species, predominant in tropical and subtropical grasslands; b) mesothermic species, predominant in temperate grasslands; c) microthermic species, predominant in cold grasslands. In a later work with Poaceae, this same classifi cation of species for phytogeographic inference was used (Boechat & Longhi-Wagner 2000). Otherwise Clark (1992) recognised for Brazil three types of grasslands associated with high altitudes, starting from the taxonomic study of a section of the genus Chusquea (Poaceae -Bambusoideae).…”
