Family:Mimosaceae
Description:Variety Description - Dwarf, amply leafy subshrubs 2.5-4 dm tall with gnarled woody caudex-branches to 1 cm diam. and axis of homotinous stem together with that of subcorymbose pseudoraceme 1.5 dm, pubescent like var. prorsiseta; leaf-formula viii-xii/ 28-45, the rachis of longer pinnae 3-8(-10.5) cm, the longer lfts (5.5-)6.5-8 mm; peduncles 2.5-6 cm; capitula without filaments ±13 mm diam.

Distribution and Ecology - Stony hillsides in cerrado, near 1000 m, known only from the type-locality at 14°30'S in s.-centr. Goiás, Brazil.-Fl. I-II(-?).

Discussion:

This ambiguous plant may be visualized as a dwarfed version of var. prorsiseta, in habit simulating M. albolanata var. paucipinna, but with the broad ellipsoid pod (20-30 x 14-15 mm) of M. claussenii sensu lato. It was found in close association with the locally endemic and strongly characterized Chamaecrista burchellii (Benth.) Irwin & Barneby.
