Abstract

Two new species of Tovomita from forests in western Amazonia are described. Tovomita colombiana and T. longirostrata are endemic to Colombia and Brazil, respectively. Both species have a similar number of secondary veins, stamens and carpels, but can be distinguished by floral bud shape and epicarp texture. Descriptions, illustrations and a distribution map of the species, plus a brief introduction about the taxonomic relevance of floral buds and stamen shape for the genus, are provided.

Resumo

Duas novas espécies de Tovomita são descritas para a porção oeste da Floresta Amazônica. Tovomita colombiana e T. longirostrata são endêmicas da Colômbia e Brasil, respectivamente. Ambas possuem quantidades similares de nervuras secundárias, estames e carpelos, mas caracteres como formato dos botões florais e textura do epicarpo são diagnósticos para a identificação das espécies. São apresentadas descrições, ilustrações e mapa de distribuição, além de uma breve introdução sobre a importância dos botões florais e estames na taxonomia do gênero.
