Abstract

The subtribe Iochrominae (Solanaceae) is represented in Brazil by two species, both with broad morphological variation. No study focusing on this subtribe has been published for the country to date. Therefore, the aim of this study is to provide a taxonomic treatment for the Iochrominae occurring in Brazil. Iochroma arborescens is widely distributed across eastern Brazil, with a few collections reported from the Central-West region of the country; whereas Vassobia breviflora occurs in the subtropical zone of the country, mainly in the South region, but also with a few records from the Southeast region. Complete descriptions, illustrations, and distribution maps for the two species are presented here. Five lectotypes are also designated.

Resumo

A subtribo Iochrominae (Solanaceae) é representada no Brasil por duas espécies, ambas com ampla variação morfológica. Nenhum estudo focado nessa subtribo foi desenvolvido para esse país até a presente data. Portanto, o objetivo desse estudo foi desenvolver um tratamento taxonômico para os táxons de Iochrominae ocorrentes no Brasil. Iochroma arborescens é amplamente distribuída na porção leste do país, e poucos registros para a região Centro-Oeste; enquanto que, Vassobia breviflora ocorre na zona subtropical do Brasil; região Sul, poucas coletas registram essa espécie para a região Sudeste. Descrições completas, ilustrações e mapa de distribuição são apresentados. Adicionalmente, cinco novos lectótipos são aqui designados.
