Specimens examined:— 5.VIII.1998, fl., fr., L.F.T. Menezes s.n. (RBR 10269); 29.V.1999, fl., fr., L.F.T. Menezes et al. 252 (RBR); 11.VI.2004, fl., L.F.T. Menezes et al. s.n. (RBR 7297); 5.IV.2008, fr., K.C. Silva 34 (RBR).

Distribution:—A widely distributed species in South America, occurring in abundance in Venezuela but less frequent in Guyana and Colombia (Martins 1989, 2009). In Brazil, it is found in the states of Roraima, Ceará, Paraíba, Pernambuco, Alagoas, Sergipe, Bahia, Minas Gerais, Espírito Santo, Rio de Janeiro, São Paulo, and Paraná, and in the Distrito Federal (Martins & Bernardo 2012).

Comments:—In Marambaia, the species occurs in Herbaceous and Shrubby Restinga. It can also be distinguished by the small leaf size (4–5.3 × 0.8–1.2 mm), rose petals, yellow anthers, and the cochlear or subcochlear seeds, with foveolate testa.
