Microstachys crassifolia sp nov (Euphorbiaceae) from Chapada dos Veadeiros, Goias, Brazil

Microstachys crassifolia, a new species from Chapada dos Veadeiros region in the State of Goias, central Brazil, is here described and illustrated. Its habit and general morphology resembles that of M. nana Silva \& Esser, an endemic species from the State of Parana, southern Brazil. Both species are hemicryptophytes from grasslands, with a well- developed underground system, glabrous leaves and reddish inflorescences and fruits, but M. crassifolia has fleshy leaves without glands while M. nana has membranaceous leaves with pateliform, submarginal glands.
