Gynoecium 5.0-6.1 mm long; ovary (2.1)2.6(3.0) mm long, stalk 0.2-0.5 mm long shortly hairy but glabrous underneath; densely covered with glands and yellow or white hairs extending almost to point of curvature; style glabrous, variable in shape, aberrations common, thickened at curvature, incurved or erect, curvature (1.0)1.4-1.8(2.1) mm high; stigma small, capitate, sometimes incurved; inserted. Discoid floral nectary folded, slightly rippled. Fruits 0.9-1.2 cm long, 0.6-0.7 cm wide; obliquely oblong (2:1) to wide oblong (1.5:1), beak straight or slightly upturned, up to 1 mm long; strongly compressed; shaggy with foxy hairs and fine pubescence, hairs longer and wispier on sides, glandular.
