Description
Variety Description - Stems 6-10 dm, in type-locality decumbent, in Minas Gerais erect-assurgent, either remotely aculeolate or rarely smooth; leaf-formula (i—)ii(—iii)/8—17; pods (in Goiás) 30-35 x 4 mm, 7-10- seeded, contracted at base into a stipe 2.5-3.5 mm, the articles 3.5-5 mm long.
Distribution and Ecology - In thin cerrado and campo rupestre, 850-1250 m, remotely scattered between e.-centr. Goiás (Chapada dos Veadeiros) and the w. slope of Sa. do Espinhaço in centr. and n.-centr. Minas Gerais.—Fl. II-V. Map 21.

Discussion
This variety and var. longipes are closely akin, but different at anthesis in length of petiole and consequently characteristic foliage. The type-collection bears a stipitate pod and I associate with it four flowering collections from Minas Gerais, two from Sa. do Cabral, and two Sa. do Espinhaço, all of which seem inseparable from it except possibly by more stiffly ascending to erect stems. The status of these will remain somewhat precarious until their fruit is known.
