A tree, the very young branchlets and inflorescences densely 
ferruginous-pubescent, otherwise glabrous or nearly so. Leaves 
11 to 15 cm long, the rachis and petioles sparingly pubescent, 
ultimately glabrous or nearly so; leaflets 5 or 7, coriaceous, 
oblong-ovate to oblong-elliptic, olivaceous, shining, 5 to 9 cm 
long, 2.5 to 5 cm wide, the base usually broadly rounded, apex 
obtuse or broadly and obtusely acuminate ; lateral nerves usually 
6 on each side of the midrib, slender, not prominent; petiolules 
5 to 7 mm long. Panicles terminal, branched from the base, 
about 20 cm long, the lower branches up to 13 cm in length. 
Flowers numerous, their pedicels about 1 cm long. Calyx dense- 
ly ferruginous-pubescent, about 1.5 cm in diameter, the lobes 
oblong-ovate, about 6 mm long, 4.5 mm wide, obtuse. Petals 
violet, glabrous, the standard reniform-orbicular, rounded, about 
13 mm wide, the claw stout, thick, with two anterior oblong, 
fleshy, 2.5 mm long appendages, wing and keel of the petals 
subequal, their claws 4 to 6 mm long. Filaments glabrous. 
Ovary oblong, densely pubescent, usually 3-ovulate.

The alliance of this species is not entirely clear, as the fruits 
are unknown. It is, however, radically different from all other 
species of the genus known to me.
