Family:Mimosaceae
Description:Variety Description - Essentially like var. claussenii, occurring in similar habitats but in discrete uniform populations, differing in antrorsely incurved-ascending setae of stems and lf-stks, the longer ones 3-5 mm long and 0.4—0.8 mm diam. at bulbous base.

Distribution and Ecology - Scattered within the range of var. claussenii but more local, especially frequent on and near Sas. dos Pireneus and dos Cristais in s. Goiás, occasional in Distrito Federal and in w.-centr. Minas Gerais.—Fl. XII-V. Map 34.

Discussion:

By definition var. prorsiseta is weakly defined, but is easily recognized and apparently stabilized in extensive populations. Its status requires further field-study.
