A remarkable new species of Ormosia (Leguminosae: Papilionoideae: Sophoreae) from Bahian Atlantic Rain Forest, Brazil


Ormosia timboënsis is described and illustrated as a new species based on fruit and leaf material collected in a fragment of Atlantic Rain Forest in central Bahia State, Brazil. This new species can be recognized by possessing the largest seed and hilum of those that have been reported in Ormosia. In addition, O. timboënsis has leaves that in combination with the fruit characters do not match any species currently described in the genus.


Ormosia timboënsis é descrita e ilustrada como nova espécie baseada apenas em material com folha e fruto coletado em um fragmento de Floresta Atlântica ombrófila na região central da Bahia, Brasil. Esta nova espécie pode ser diferenciada por possuir semente e hilo dentre os maiores já vistos em Ormosia. Além disso, O. timboënsis apresenta folhas que em combinação com os caracteres do fruto não permitem acomodá-la em nenhuma das espécies atualmente descritas no gênero.
