Family:Mimosaceae
Description:Variety Description - Stems at first anthesis tufted 1-4 dm, later diffusely elongating or humifuse; otherwise as described in keys to subspp. and vars.

Distribution and Ecology - In campo sujo and open cerrado subject to periodic fires, 950-1200 m, locally abundant in Distrito Federal, extending weakly w. into valleys of rios Descoberto and Corumbá in adj. Goiás.—Fl. IX-III, sporadically to VI, fruiting and progressively defoliate (II-)III-IX.

Discussion:

Within the Federal District var. brevissima is almost always readily distinguished from var. gracilis by few short, mutually remote and paucifoliolate pinnae. In the dry season, when the leaflets have dropped but leaf-stalks mostly persist, it superficially resembles allopatric M. phyllodinea, M. paucifolia, and M. piptoptera (under which the differences are briefly discussed).
