18. Calopogonium Desvx. 1 — Flowers almost those of Galactia ; 

 2 superior catyx-lobes distinct or connate with one 2-toothed. 

 Standard obovate, 2-auriculate at base ; wings narrow ; keel shorter 

 than, and adhering to wing, obtuse. Stamens 10, 2-adelphous 

 (9-1) ; anthers uniform. Germen sessile oo-ovulate ; style slender 

 beardless ; apex capitate stigmatiferous. Legume linear piano-com- 

 pressed or convex septate within between seeds, 2-valved. Seeds 

 orbicular, rather compressed, exarillate. — Herbs or undershrubs, 

 twining ; leaves pinnate, 3-foliolate stipellate ; flowers small, 2 in elon- 

 gated or short racemes, fascicled in aril of each bract ; rachis of 

 fascicle node-like ; pedicels very short ; bracts and bractlets small 

 caducous 3 {South and Central America"). 



19. Mastersia Benth. 5 — " 2 superior calyx-lobes connate into one 

 entire broad. Standard suborbicular, very shortly unguiculate, 

 exauriculate ; wings obliquely oblong ; keel broad slightly curved 

 obtuse, nearly equal to wings. Vexillary stamen free from base 

 upwards, straight, remainder connate; anthers (5 ? or all?) linear ver- 

 satile. Ovary sessile cc -ovulate ; style short, filiform curved, beardless ; 

 stigma terminal capitate." Legume oblong-linear piano-compressed 

 indehiscent ; superior suture slightly winged. Seeds oo, transversely 

 oblong, exarillate ; hilum small lateral. — An undershrub (?) ; stem 

 twining ; leaves pinnate 3-foliolate stipellate ; stipules very caducous ; 

 flowers in elongated axillary racemes, fascicled in axil of each bract ; 

 rachis of fascicle node-like or very shortly developed ; bracts in 

 pairs, caducous, bractlets suborbicular, persistent for a long time 6
