Species Description - Foliage (so far as known) glabrous, bright green, blue-green, or pallidly glaucescent; larger stipules contiguous or imbricated, concealing the stem, 15-26 x 10-20 mm, at apex broadly rounded to broadly deltate-subacute, persistent; lf-stalk 7-20(-24) mm; gland 0.4-1.7 mm diam, sessile or almost so; larger lfts up to (20-)25-38(-46) x (10-) 12-21(-23) mm; pedicels 22-42(-50) mm; long petals (14-) 16-21 (-25) mm; pod 40-65(-70) x (6-)7-9.5(-10.5) mm; ovules (15-) 16-21 (-23).
Distribution and Ecology - Virgin and disturbed cerrado, sometimes weedy along roads and in rough pasture or coppiced woodland, mostly 300—1200 m, ascending on Chapada dos Veadeiros in e.-centr. Goiás to 1600 m and descending along the lower Paraguay and Paraná rivers to ±100 m, widespread over the Brazilian Planalto from Chapada Diamantina (Sa. do Sincorá) in Bahia s. along Sa. do Espinhaço to s. Minas Gerais (Caxambú) and e. São Paulo (Guararema) and w. and s. over s. Goiás and s. Mato Grosso to extreme s.-e. Rondônia, centr. Paraguay, n.-e. Paraná, and extreme n. Argentina (Ituzaingó, prov. Corrientes).

Discussion
The variety may be visualized ideally as a coarsely leafy, always glabrous version of var. mollissima with very large obtuse stipules upwardly imbricated to conceal the stem. Alike in Goiás and Minas Gerais var. glauca fades by way of populations with stipules either broadly acute at apex or shorter than the internodes, or both, into amply leafy var. mollissima.

Objects
Collections of var. glauca, equivalent of C. latistipula sensu Irwin (1964, p. 56, fig. 338, q.v. for discussion of variability), have doubled since 1964, filling out the already known range in planaltine Brazil and extending it north into Bahia and south into Paraná. Vouchers (NY) for the new limital records are: Bahia: Sa. do Sincorá, 19 km n.-e. of Ibicoara, 1.II.74 (fl, fr), Harley et al. 15767. Rondônia: Vilhena, 3.I.79 (fl, fr), M. G. Silva & A. Pinheiro 4120. São Paulo: Guararema, on roadside, 24.IX.67 (fl, fr), Moreira de Souza in herb. I. A. C. 19562. Paraná: Nova Esperança, 3.IX.69 (fl, fr), Hatschbach 22163.
