Abstract

Aristolochia disticha was originally described based on a specimen collected by R. Spruce in Santarem (Pará, Brazil). Unfortunately, the specimen lacks flowers and fruits, although it has four slender, ramiflorous inflorescences that distinguish the species. Here we fully describe the species, based on the holotype and additional flowering and fruiting specimens that allow us to report a range expansion to the states of Acre, Amazonas, Bahia, Paraíba, and Rio Grande do Norte, Brazil, and also to Venezuela, French Guiana, Surinam, Peru, and Bolivia. Finally, we reduce the recently described A. setulosa to the synonymy of A. disticha.

Resumo

Aristolochia disticha foi originalmente descrita com base em um espécime coletado por R. Spruce em Santarém (Pará, Brasil). Infelizmente, a amostra carece de flores e frutos, embora tenha quatro inflorescências ramifloras delgadas que distingue a espécie. Aqui é fornecida a descrição completa da espécie, com base no holótipo e em amostras adicionais com flores e frutos, que nos permite registrar uma ampliação de ocorrência da espécie para os estados do Acre, Amazonas, Bahia, Paraíba e Rio Grande do Norte (Brasil), e para Venezuela, Guiana Francesa, Suriname, Peru e Bolívia. Finalmente, é aqui considerada como sinônimo de A. disticha, a recentemente descrita A. setulosa.
