Scientific Name:Trigonia floccosa Rusby
Description:Description - Scandent shrub, the branches terete, lenticellate, strigose or adpressed-lanate, becoming glabrous with age. Stipules subulate to lanceolate, 10.0-12.0 mm long, tomentellous, caducous; petioles 5.0-15.0 mm long, ca 1.5 mm wide, strigulose; lamina ovate to obovate, inequilateral, 4.0-13.0 cm long, 2.0-6.0 cm wide, subcoriaceous, the margins entire, the apex acute to acuminate, the base subcordate; venation eucamptodromous, lanate to glabrous along the midrib above, strigose beneath, the midrib plane above, prominent beneath, secondary veins impressed above, prominulous beneath; intercostal pubescence arachnoid-lanate to glabrous above, adpressed white-lanate and golden-strigose beneath. Inflorescences terminal and subterminal axillary thyrses, to 12 cm long. Flowers in cymules of 1-2, peduncles absent or nearly so;pedicels 1.0-1.5 mm long, ca 0.4 mm thick, tomentellous, bracts and bracteoles of equal size, 2.5-10.0 mm long, subulate, tomentellous; sepals ovate to oblong, sometimes deltoid, 3.5-5.2 mm long, 2.0-2.5 mm wide, papillate at the margins, lanate or strigose; standard 5.0-5.5 mm long, 2.5-3.0 mm wide, the pouch extending along 1/3 of the length, slightly revolute at the apex, barbate at the throat, the wings spathulate, 5.0-5.5 mm long, ca 1.5 mm wide, densely barbate at the base, the keel petals 4.04.5 mm long, ca 3.0 mm wide, the pouch nasiform; stamens 8-9, fertile ones 6-7, staminodes 2, the filaments 1.8-2.0 mm long, connate for ½ of the length, anthers oblong, 0.8-1.0 mm long, ca 0.4 mm wide; glands 2, 2-3 lobed, 0.5-0.8 mm per side, acute at the apex, fused to the staminal tube; style 1.8-2.0 mm long, villous, the stigma trilobate, ca 0.3 mm in diameter; ovary subglobose, ca 0.6 mm in diameter, villous, the ovules numerous. Fruit (immature) 5.0-6.0 cm long, ca 1.2 mm per side; exocarp velutinous-tomentose; endocarp woody, glabrous. Seeds 8-10 per locule, subglobose, ca 3.0 mm in diameter, barbate pubescent, the trichomes ca 12 mm long.

Discussion:This species can easily be recognized by the dual pubescence types on the underside of the leaf, by the large glands fused to the staminal tube, and especially by the papillae on the sepals.
