Discussion:Known to us through J. Revilla 504 and 788 (both NY) from rio Ampiyacu in Maynas and through Kujikat 287 (MO) from rio Cenepa in Amazonas Peru and through Prance et al. 10733 (NY) from Rio Uraricoeira, Terr. do Roraima, Brazil, resembles var. tenuifolia in general habit, short style and oblanceolate staminodes, but differs in having several petiolar glands, a smaller perianth (longest petal 13-15 mm) and slender long anthers (±1.3, not 1.6-2 mm diam). More material is needed.
