  • Discussion

    Collected in flower from April to June.

    This species is most closely related to Banisteriopsis scutellata and B. basifixa, from which it can be distinguished by its short petioles, smaller lanceolate leaves with sericeous pubescence, shorter inflorescences of 3-5 umbels, and small calyx glands. In leaf size, shape and pubescence, B. parviglandula resembles B. pseudojanusia.

    The name refers to the very small calyx glands.

  • Distribution

    In woodland in SE Minas Gerais in Brazil, apparently extending south into the state of Rio de Janeiro.
