 divaricate at both ends, very flat ; spreading or trailing herb, .... D. obcordatum. 

 O Pod-joints securiform, the basal one long-stalked. 

 Calyx about a line, the corolla 5 lines long ; stalk of basal pod-joint about 1 — \ lin. 



long, D. scalpe. 



Calyx and corolla half the size ; stalk of basal pod-joint slender, \ in. long, 



. . D. podocarpum. 

 + + Pod-joints truncate at both ends, oblong to linear-oblong and 

 sessile. 

 O Leaves pinnately 3-foliolate. 

 Pod-joints only 1| — 2 lin. long by \ — f lin. broad, densely hooked puberulous, not 



narrowed at the ends, D. recurvatam. 



O Leaves simple, the petiole short. 

 Pod-joints 6 — 8, f in. long, slightly narrowed at both ends, irregularly striate, shortly 



glandular-pubescent ; petioles longer or shorter, D. ormocarpoides. 



Very near the preceding, the petiole very short ; pod-joints 10 — 12, about 3 lin. long 



and hardly a line broad, shortly glandular-pubescent, B. teres. 



x x Pod-joints narrow, as long or only twice as long as broad. 



+ Shrubs or more usually erect or spreading perennials. Pod- 

 joints usually as long as broad, more or less rotundate with 

 truncate ends. 

 O Leaves simple. Pod-joints indented at the lower suture, 

 about a line long. 

 Perennial, erect, slightly appressed-pubescent ; racemes elongate and very slender ; 



pod-joints sparingly and shortly hispid ; leaves acute, D. Gangeticwm. 



As preceding, but diffuse, the leaflets broader and usually blunt, D. Jlexaosum. 



Shrub, densely pubescent ; racemes tomentose, rather short and robust ; pod-joints 



densely and shortly grey hirsute ; leaves blunt, ; D. latifolium. 



Leaves 3-foliolate. Pod-joints about a line long and broad. 



Erect shrubby perennial ; leaflets somewhat repand, giaucescent beneath, acute or 



acuminate ; branchlets almost terete ; pod-joints densely covered with hooked 



stiff hairs, D. sequax. 



Diffuse perennial, the branches sharply 5 — 6-angular ; leaflets entire, blunt ; pod-joints 



sparingly covered with white hooked stiff hairs, D. diffusum. 



+ + Shrubs or woody undershrubs. Pod-joints usually about 

 twice as long as broad, more or less indented on one or 

 both sutures. 

 O Bracts of the young inflorescence scarious and large, forming- 

 imbricate cones, very deciduous, but the basal ones usually 

 remaining persistent, 

 f Basal pod-joint sessile. 

 Racemes sessile or peduncled, rather short ; pod-joints 1^ — 2 lin. long and nearly as 

 broad, indented on the lower suture, appressed hirsute ; branchlets sharply angu- 

 lar, often villous on the corners, • D. Jioribundum. 



f f Basal pod-joint shortly but distinctly stalked; 

 Racemes slender, long-peduncled, forming spreading terminal panicles ; pod-joints 

 \ in. long and 3 lin. broad, puberulous, slightly indented ; branchlets terete or 

 nearly so, , , , , , , , D. tiliccfoUioii .
