Liana to 6 cm in diameter, the bark dark, fibrous, irregularly striate; attached to supporting tree by adventitious rootlets; phloem of stem irregularly many-armed in cross section; dimorphic, the juvenile plant with small leaflets, 1-2 cm long and 4-8 mm wide, climbing straight up tree trunks, often rooting at nodes; branchlets terete, puberulous to glabrous, the nodes usually without interpetiolar glandular fields; pseudostipules ovate, longitudinally striate. Leaves 2-foliolate, often with a trifid uncate tendril especially when young; leaflets when young narrowly ovate to lanceolate, mucronate at tip, basally rounded, when mature narrowly ovate to ovate, acute to acuminate, cuneate to truncate, 5.0-16 cm long and 1.2-6.9 cm wide, membranaceous, scattered lepidote above and beneath, otherwise glabrous above and beneath, or sparsely puberulous especially along main veins or rarely densely puberulous over whole under surface, a few plate-shaped glands near midvein beneath, drying dark green or dark olive to almost black, the main veins drying reddish below; mature petiolules 0.8-3.5 cm long, petiole 1.1-6 cm long, glabrous or subpuberulous. Inflorescence an axillary panicle usually reduced to 1 or 3 flowers, rarely to 15 flowers, the branches more or less glabrous. Flowers with the calyx membranaceous, cupular with a sinuous margin, subtruncate, glabrous to slightly lepidote, often with scattered glands, 5-18 mm long and 8-18 mm wide; corolla yellow with ca 9 orange lines in the throat, tubular-campanulate, 4.5-10 cm long and 1.2-2.4 cm wide at mouth of tube, the tube 3.3-6.9 cm long, the lobes 1.2-3.1 cm long, glabrous outside, glabrous or slightly simple puberulous along throat ridges inside, pubescent with simple jointed trichomes at the level of stamen insertion; stamens didynamous, the anther thecae divaricate, 3 mm long, the filaments 1.2-2.4 cm long, the staminode 0.5-1.5 cm long, occasionally developed into fifth stamen, insertion 4-8 mm above base of corolla tube; pistil 2.8-3.8 cm long, the ovary linear, 6-7 mm long and 1.2 mm wide, minutely lepidote to subpuberulous, the ovules 4-seriate but appearing 2-seriate in most cross sections; disc annular, 1-1.5 mm long and 3-4 mm wide.
