312 NATURAL HISTORY OF PLANTS. 
by ‘persistent calyx.—Herbs or undershrubs; leaves pinnate 3- or 
more rarely 5~7-foliolate; lower leaves more rarely 1-foliolate; 
leaflets stipellate ; stipules 2, acuminate, striated at base ; flowers’ in 
terminal, dense or much elongated and spiciform, racemes; pedicels 
in pairs, hooked-inflexed at apex; bracts variable, persistent or 
deciduous (Zropical Asia, Africa, and Australia’). : 
158? Lourea Necx.*—Flowers of Uraria; calyx broadly cam- 
panulate, nearly equally 5-lobed, after anthesis accrescent mem- 
branous and longer than fruit. Legume 2-0 -seeded; segments 
ovate compressed, rather turgid, bent back and nestling in bottom 
of calyx.—Erect or prostrate herbs; habit of Desmodium; leaves 
1-8-foliolate ; leaflets stipellate, usually broader than long; stipules 
2, subulate or striated; flowers‘ in slender loose racemes ; pedicels 
usually in pairs; bracts acuminate caducous (Zropical Asia and 
Australia’). 
159. Mecopus Breny.‘’—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’ crowded, in 
dense oblong terminal racemes; bracts elongated subulate, hooked 
at apex; pedicels in pairs, hooked at apex and coiled round flower 
(Zropical Asia’). 
160. Alysicarpus Nucx.’—Calyx glumaceous; lobes 5, deep, 
1 Purplish or yellowish.
