Rediscovery of Panicum brachystachyum Trin. (Poaceae) on the Espinhaço mountain chain in Minas Gerais state, Brazil

Abstract

Panicum brachystachyum, a Poaceae species previously thought to be extinct was rediscovered in the Parque Natural Municipal Ribeirão do Campo, Conceição do Mato Dentro, Minas Gerais, Brazil. A redescription and an illustration of the species are presented, emphasizing the rhizomatous habit and caryopsis, aspects not to be found in the literature. The hypothesis of this species being endemic in the Serra do Cipó region is strengthened.
