and peduncles rusty-pubescent. Leaf-rachis 3-6 in. long, with a 
sessile gland near the base and usually between the uppermost pinne ; 
pinne 4~7-jugate; leaflets 8—15-jugate, oblong-trapezoidal, sessile,

late above, pubescent beneath; 4-4 in. long, } in. broad more or less. 
Stipules deciduous, often on the flowering extremities 3—5 lines long, 
obliquely ovate, pubescent. Peduncles 1-2 in. long, axillary or fas-
