Inflorescences terminal and subterminal axillary panicles, sometimes reduced to racemes, to l0.0 cmlong. Flowers in groups (cincinni) of 1-3 (usually 1); peduncles, when present, 0.1-0.5 mm long, strigose, the bracts ovate, 4.04.5 mm long, 1.5-2.5 mm wide, the pedicels 0.5-1.0 mm long, ca 0.5 mm thick, strigose; sepals oblong to deltoid, 4.0-6.0 mm long, 2.0-4.0 mm wide, strigose on the exposed portions, lanate on the protected areas, acute to rounded at the apex; standard 6.0-6.5 mm long, 4.5-5.0 mm wide, the pouch extending 1/3 of the length, the upper portion erect to revolute, barbate at the throat, the wings spathulate, 5.5-6.0 mm long, 2.5-3.0 mm wide, the apex rounded, densely barbate at the base, the keel petals 4.5-5.0 mm long, 2.5-2.8 mm wide, the pouch extending along most of the length, the apex revolute; stamens 8, 6-7 fertile, 1-2 staminodes, the filaments 2.5-3.0 mm long, free along ½ of the length, the anthers oblong to obovate, 0.6-1.1 mm long, ca 0.6 mm wide, one of them smaller; glands 2, 2-lobed, more or less rectangular to trapezoid, ca 0.6 mm high, 1.0 mm long, glabrous to slightly pilose; style 2.5-3.0 mm long, barbate, the stigma trilobate, approximately triangular, 0.5-0.6 mm per side; ovary subglobose, 1.0-1.5 mm in diameter, barbate-pubescent, the ovules numerous.

Discussion
This species is a close relative of Trigonia echiteifolia Rusby, from which it differs in its larger flowers, broader bracts and bracteoles, larger number of secondary nerves on the leaves, and in the shorter peduncles.
