trichomes, especially on ribs, these simple, forked and variously dendroid; inter-petiolar glands lacking; pseudostipules foliaceous, 0.6-1.6 cm long and 0.6-1.4 cm wide, persistent. Leaves 3-or 2-foliolate with a tendril or tendril scar; leaflets ovate, acuminate, cordate to subcordate, 7.6-12.6 cm long and 5.4-8.8 cm wide, membranaceous, palmately veined at the base, the secondary veins 4-5 on each side, strongly lepidote above and beneath, villous above with simple or weakly dendroid trichomes and beneath with much branched dendroid trichomes, golden brown when dry; tendril trifid, 8-18 cm long to branching, the 3 arms 0.8-1.7 cm long, often recurved at the tip; petiolules 1.3-3.7 cm long, petiole 3.0-5.1 cm long, lepidote and villous. Inflorescence a terminal raceme on a short erect lateral branch, the branches lepidote and dendroid-villous, each flower subtended by a pair of narrow bracts below the calyx and a single bract below the pedicel. Flower with the calyx double, the inner calyx 2-3-labiate, the outer calyx more or less 5-lipped, 1.2-1.4 cm long and 1.2-1.9 cm wide, densely lepidote, densely den-droid-villous below the outer calyx lobes, sparsely so on them; corolla yellowish white when young, turning deep purple, tubular, 2.2-2.6 cm long and 0.6-0.9 cm wide, the upper 2 lobes fused and thick, 1 mm long, the lower 3 fused, 6-8 mm long, the tube bilabiate, split about half its length, the 2 lips remaining loosely fused until forced apart by pollinator, viscid, mostly glabrous, glandular-lepidote on the ridge at the level of stamen insertion; stamens didynamous, the anther the-cae divaricate, 2 mm long, the longer filaments 1.4-1.6 cm long, the shorter fila-ments 1.2-1.3 cm long, the staminode 3-4 mm long, inserted 5 mm from the base of corolla tube; pistil 2.1-2.3 cm long, bent near the base, ovary truncate-conical, 2.5 mm long, 2 mm wide, rough-surfaced and lepidote, the ovules multi-seriate in each locule; disc annular-pulvinate, 1.5 mm long, 3.5 mm wide. Capsule (Lehmann 7691, Cali, Colombia, K) elliptic, compressed, 7.5 cm long and 4 cm wide, the valves woody, densely rugose-tuberculate with the closely packed tuber-cles ca. 2 mm long, pubescent with dendroid and simple trichomes, appearing yellowish from the trichomes; seed 1.2-1.3 cm long and 4.7-4.9 cm wide, bialate, the wings thin, brown to almost hyaline at the tip, distinct from the darker brown puberulous seed body.
