Distribution and Ecology - In cerrado near 800 m, known only from Sa. do Morcêgo on the Paranã-São Francisco watershed near 14°30'S in e.-centr. Goiás.—Fl. IV- V(-?).

Discussion:

The var. vespertilionis has nearly the leaf-formula of var. corneiseta, but shorter, more condensed pinnae and narrower leaflets; it is a shrub, not pachycaulous. It differs from sympatric M. foliolosa var. paranani in longer leaf-stalks, more crowded pinnae (3.5-6, not 7-12 mm apart), much longer peduncles (4.5-7, not 1.5-3.5 cm), and longer bisexual flowers (7-8, not 5-6.5 mm long).
