Description:Variety Description - Lfts 4 pairs, elliptic-obovate, glabrous except for tuft of hairs in distal basal angle or along distal side of midrib on dorsal face only, the margin re volute; tertiary venulation of both faces prominulous; fl-buds remotely pilosulous glabrescent; longer sepals ±8.5 mm; longer petals 15-16 mm; pod ±15 x 1.4 cm, the valves coarsely venulose; seeds ±7x3 mm, the areole 4.5-4.8 x 1.4-1.6 mm.—Collections: 1. [Key: "Fls larger, the longer sepals 8.5-11 mm, the longst petal 14-19 mm. Lower face of lfts pilosulous only in distal basal angle of midrib; pod ± 14 mm wide; s. Espirito Santo (Furno Grande)."]

Distribution and Ecology - On flagstone rock near 1200 m, known only from the mountain Forno Grande near 20°30'S, 41°07'W in s. Espirito Santo, Brazil.—Fl. (III?)-VI.

Discussion:Reluctant as we are to describe single specimens, we cannot otherwise dispose of this striking variant of S. neglecta, so different from all others in the broad pod. In other respects it seems intermediate between var. grandiflora, vicariant northward, with which it agrees in the relatively large flowers, and var. oligophylla, vicariant south westward, which is similar in pubescence of the leaflets. From the last and from the population of var. neglecta seemingly isolated on neighboring Sa. de Caparao it is handily distinguished by the large flower.
