Leaves 2-4, smoky-green: petioles filiform, rigid, 2-5 cm long, abruptly swollen and pulvinate both at the apex and at the base above the basal articulation: leaflets 7-13, linear, 0.8-5 cm long, about 2 mm broad, ecallose, conspicuously channelled (in section U-shaped), slightly falcate towards the apex, the margins converging at the apex as in the prow of a boat. Peduncles 1.5-2 cm long, with 2 alternate subulate bracts, about 2 mm long, near the apex. Sepals oblong-lanceolate, obtuse, ecallose, 7 mm long, with minute purple striae. Corolla about 2 cm long, pale rose, with a rather broadly funnel-shaped yellowish tube: petals cuneate, rounded at the apex, slightly attenuate towards the base, with 2 blood-red papillate swellings, 3 mm long, on the margins at the base. Filaments glabrous, the longer 6 mm long, shortly and obtusely toothed, blood-red below from the base to the teeth, pale in the free part. Ovary oblong, the chambers 3-ovuled, like the styles glabrous.
