 Leaflets 5-7 pairs. Racemes rather ovate. Bracts lanceolate, with a long

 Legumes linear-lanceolate, 2-3 inches \or\g.— Clavimy Locust.— R. dubia,

 April-May.— Shrub 4-8 feet high (or in cultivation larger) : young branches 

 reddish, very hispid. Leaflets oval or roundish, 5-6 pairs. Flowers about 

 twice the size ot those of R. Pseudacacia, deep rose-color, inodorous. — The 

 R. hispida, var. rosea of Elliott is said to have spiny stipules, and the branch-

Calyx without bracteoles, about equally 5-toothed or 5-cleft. Vexillum 

 large, roundish, spreading or reflexed, usually silky or pubescent on the out- 

 side: keel obtuse, cohering with the wings. Stamens monadelphous or 

 sometimes diadelphous ; the tenth filament sometimes half united with the 

 others. Style filiform, bearded longitudinafly, or glabrous : stigma terminal. 

 Legume commonly sessile and much compressed, linear, many-seeded ; 

 valves usually flat. Seeds compressed.— Shrubby or herbaceous plants, 

 erect or procumbent, silky-villous. Leaves unequally pinnate (rarely reduced 

 to a single leaflet). Stipules free from the petiole, lanceolate or subulate, 

 never sagittate. Racemes terminal or opposite to the leaves, or axillary. 

 Flowers white or purplish. 



The North American species are all herbaceous plants; with the lobes of the 

 calvx broad at the base and acuminated; the style longitudinally bearded on the 

 inside ; and the legumes more or less hispid, villous, or velvety : they belong to the 

 section Brisso\ia, DC. : but the stamens are mostly diadelphous.
