Abstract

Nine species of the Brazilian endemic genus, Trembleya, were collected during a floristic survey of the tribe Microlicieae on Serra do Cabral, an isolated mountain range in north-central Minas Gerais State, Brazil. Four of these are newly described and illustrated here: Trembleya inversa, T. purpurascens, T. rubra, and T. serrulata, represent new taxa for the genus. These new species appear to be endemic to Serra do Cabral where they occur in campo rupestre and cerrado vegetation. Serra do Cabral has the distinction of harboring more species of Trembleya than any other mountain range in Brazil.

Resumo

Nove espécies do gênero brasileiro Trembleya foram coletadas durante um levantamento florístico da tribo Microlicieae na Serra do Cabral, uma cadeia isolada de montanhas no centro-norte do estado de Minas Gerais, Brasil. Quatro delas, que representam novos táxons para o gênero, são aqui descritas e ilustradas pela primeira vez: Trembleya inversa, T. purpurascens, T. rubra, e T. serrulata. Estas novas espécies parecem ser endêmicas da Serra do Cabral onde ocorrem no campo rupestre e cerrado. A Serra do Cabral distingue-se por abrigar mais espécies de Trembleya do que qualquer outra cadeia de montanhas no Brasil.
