Abstract
VALDES-REYNA, Jesús; ZULOAGA, Fernando O.; MORRONE, Osvaldo and ARAGON, Laura. Taxonomic treatment of Panicum (Poaceae: Panicoideae) from Northeastern Mexico. Bol. Soc. Bot. Méx [online]. 2009, n.84, pp.59-82. ISSN 0366-2128.
A taxonomic treatment of the genus Panicum for Northeastern Mexico, which includes the states of Coahuila, Nuevo Leon and Tamaulipas is presented. The area is considered a centre of origin and plant diversification for the arid and semi-arid zones for the country, where the agriculture and livestock activities are important. The genus is the most diverse in tribe Paniceae, with a cosmopolitan distribution, and 19 species are distributed in Northeastern Mexcio. A key to the genera that have been recently segregated from Panicum is presented. In addition, distribution maps are included and species relationships are discussed.
