A new species of Paspalum (Poaceae, Panicoideae, Paspaleae-Recta group), from the cangas of the Serra dos Carajas, Para, Brazil

摘要

A new species, Paspalum cangarum, morphologically similar to P. brachytrichum, is described. While both occur in canga vegetation, P. brachytrichum is endemic to the state of Minas Gerais and the new species is restricted to the Serra dos Carajas, state of Para, Brazil. These species can be distinguished from each other mainly by their height, length and number of racemes and by the lengths of their pedicels and spikelets.
