A shrub or small tree with grayish or grayish-brown branches, the twigs, branches of the 

 inflorescence, petioles, rachis, and under surface of the leaflets more or less densely hispidulous, 

 especially when young; leaves odd-pinnate or occasionally equally pinnate through the sup- 

 pression of the terminal leaflet, 12-17 cm. long; petioles terete or nearly so, 2.5-4 cm. long; 

 rachis with or without wing-margins, the wings recurved; leaflets 5-11, oblong-obovate to 

 obovate, 5-8 cm. long, 1.5-3 cm. broad, rounded or obtusely short-acuminate at the apex, 

 cuneate at the base, hispidulous above; panicles axillary, shorter than the petioles; flowers 

 short-pedicellate; calyx 4- or sometimes 5-parted, the lobes short-ovate or short-triangular- 

 ovate, hirsute on the back; petals 4 or sometimes 5, broadly elliptic to oval or ovate, 4—4.5 

 mm. long, 2-3 mm. broad, acute or rounded at the apex, hispidulous on the back; staminal 

 tube subcampanulate, pilose without and on the inside, 8- or occasionally 10-lobed, each lobe 

 cleft; anthers sessile between the teeth; ovary subglobose, glabrous, sessile in the shallow 

 saucer-shaped disk; style about as long as the ovary; stigma depressed; capsule 3-valved, 

 coriaceous, the valves dehiscent to the middle or below; seeds 3 or 4, elliptic, flattened, con- 

 cave on the inner face. 



In the variety the young twigs, petioles, and rachis are velvety-hispidulous; leaves 15-22 



cm. long; leaflets 3-9, broadly obovate, 5-13 cm. long, 2.5-5.5 cm. broad; ovules solitary in
