Leaflets to 6 on each side of the rachis, unequal, ± sigmoidal, inequidistant, 1-9 cm apart, except those of the apical leaflet pair, long-acuminate to subfalcate, green above and with prominently elevated costae, paler underneath and generally glabrous, rarely with sparse ramentae along the costae; basal leaflets 1-4-costate, c. 8.5-15 x 0.7-3 cm; middle leaflets 6-7-costate, c. 21-29 x 6-8 cm; apical leaflets 5-8-costate, c. 9-14 x 4-6 cm, joined to 9 cm at the base along the rachis, the apex incised to as many lobes as there are costae, the lobes to 1 cm long and further incised at their tips to 5 mm deep, resulting secondary lobes acute-acuminate. Inflorescence infrafoliar, pendulous; prophyll not known; peduncle c. 1.5-3 x 0.2-0.4 cm, flattened, glabrous, the inflorescence very rarely simple and unbranched; rachillae often 2-3, rarely 4 or more, each to 8-15 cm long, flattened, to 3 mm wide, 1.5 mm thick when dry, glabrous, drying finely striate, the subtending bract a narrow, low collar.
