 terminal, dense or much elongated and spiciform, racemes ; pedicels 

 in pairs, hooked-inflexed at apex ; bracts variable, persistent or 

 deciduous {Tropical Asia, Africa, and Australia-). 



158? Lourea Neck. 3 — Flowers of Uraria ; calyx broadly cam- 

 panulate, nearly equally 5-lobed, after anthesis accrescent mem- 

 branous and longer than fruit. Legume 2-co -seeded ; segments

159. Mecopus Benn. 6 — Flowers of Desmodium ; keel much curved, 

 obtuse. Stamens 10, 2-adelphous (9-1). Germen shortly stipitate ; 

 ovules 2 ; style inflexed ; apex minute stigmatiferous. Legume 

 supported on a very long stalk, much exserted from inverted calyx, 

 lodged within bracts close to axis of spike; segments 1, 2, com- 

 pressed convex reticulated indehiscent. Seeds reniform exarillate. — 

 A slender branched herb ; leaves 1-foliolate ; leaflets 2-stipellate 

 reniform ; stipules 2, lanceolate setaceous ; flowers 7 crowded, in
