 Flowers in long racemes ; bracts and bractlets long, setaceous ; calyx \ — \ in. long ; 



pods \ in. long, ft sessiliflora. 



O Pods very much, exserted from the calyx. Calyx- tube obliquely 

 bell-shaped, the teeth rather short, barely enlarging in fruit. 



U Bracts subulate, very minute. Flowers yellow. 



A Branches and branchlets woody, with medullary 

 pith, terete. 

 Almost glabrous ; leaves acute ; racemes temiinating axillary branchlets or reduced to 



axillary flower- clusters, , ft Eurzii. 



A A Branches herbaceous, fistulose, stout. 

 Calyx and underside of the blunt or acute leaves densely appressed silky ; racemes all 



terminal, ft A.ssamica. 



Thinly appressed silk-hairy ; leaves refuse to blunt ; racemes all terminal, . ... ft retusa. 



IT H Bracts ovate to ovate-lanceolate, up to 4 lin. long, 

 reflexed. 

 Glabrous ; leaves blunt to acute, almost sessile, glaucous-green ; pods stalked ; branches 

 stout, fistulose, ft sericea. 



* * Ovary variously clothed, from villose to tomentose and appressed silk-hairy. 



Pods similarly clothed, rarely minutely pubescent and appearing glabrous to 



the naked eye. ('Flowers racemose.) 



+ Stipules none, or small and subulate. Flowers yellow. 



x Pods minutely appressed-pubescent, appearing glabrous to the 

 naked eye. Calyx glabrous. Leaves narrow. 



Glabrous ; bracts linear, very minute ; leaves narrow-linear, ft neriifolia. 



x x Pods and calyx brown or dark brown tomentose or pubescent, 

 leaves narrow. 



Stems sulcate, but not angular ; pods sessile, 1 — 1 \ in. long, ft juncea. 



Stems sharply 4-angvdar ; pods shortly stalked, l\ — 2 in. long, ft tetragona. 



+ + Stipules large, leafy, half-lunate. Flowers blue or rarely greenish 

 white. 

 Stems angular, more or less puberulous to glabrous ; leaves rhomboid ; pods pubescent, 



. . ft verrucosa. 

 B. Foliolatjb. Leaves 3 — 7-foliolate. 



* Leaves digitately 5 (occasionally 3) — 7-foliolate. 



Leaves 5-foliolate ; flowers rather large, yellow, racemose ; bracts 3 — 4 lin. long, linear, 

 acuminate, reflexed ; pods glabrous, stalked, \\ — 1^- in. long, .... ft quinquefolia. 



* * Leaves digitately 3-foliolate. 



x Pods inflated. 



+ Pods short, globular or obliquely ovoid, 1-2-4-seeded. 

 Stipules and bracts minute, subulate ; flowers small, by 1 — 2 (rarely 3 — 4) terminating 

 slender leaf-opposed peduncles ; pods acuminate, minutely appressed pubescent, 



1 — 2-seeded, ft medicaginea. 



+ + Pods oblong to linear-oblong, many-seeded. 



Pods indistinctly appressed-pubescent, linear-oblong, 1 — -lj in. long, C. striata. 



Pods densely tawny-villous, boat-shaped-oblong, somewhat curved, f — J in. long,
