sometimes a little connate), imbricated in estivation. Petals unequal : 
standard elongated acute, recurved or reflexed, furnished with an 
appendage within above claw; wings shorter, slightly adhering to 
keel; keel curved beaked, petals connate. Stamens 10, 2-adelphous 
(9-1); anthers uniform. Germen stipitate, pauci-, usually 1-2-ovu- 
late ; style slender beardless ; apex capitate stigmatiferous. Legume 
stipitate, obliquely ovate-oblong; valves 2, convex coriaceous: 
Seed thick orbicular exarillate, half surrounded by linear hilum.— 
Shrubs or undershrubs, twining glabrous ; leaves pinnate 3-foliolate 
stipellate ; stipules 2, lateral small; flowers' fascicled in simple or 
oftener branched elongated axillary racemes; rachis of fascicle 
node-like; bracts small or minute, bractlets minute orbiculate, 
very caducous (Ceylon, South Sea Islands’). 
22. Rudolphia W.'—Flowers almost those of Hrythrina. Calyx 
coriaceous, gamosepalous to a considerable height, tubular sub-2- 
labiate, 2 superior lobes connate into one, entire or shortly emar- 
ginate or cleft at apex; lowest a little longer, long acuminate, 
somewhat arched ; 2 lateral much smaller or hardly visible. Corolla 
and stamens of Hrythrina. Germen sessile or stipitate, oo-ovulate ; 
style usually thickened at middle, hooked beardless at apex ; summit 
capitate stigmatiferous. Legume surrounded at base by persistent 
calyx, elongated plano-compressed, shortly acuminate or mucronate 
at apex, thinly stuffed within, 2-valved; valves finally twisted. Seeds 
flat—T wining herbs ; leaves 1-foliolate articulated stipellate ; stipules 
narrow deciduous ; flowers‘ subaxillary racemose ; fascicles alternate ; 
rachis of fascicle node-like ; bracts and bractlets narrow (West Indies‘). 
23. Mucuna Apams.'—Receptacle cupuliform, lined by a disk’; 
disk somewhat projecting round gynzceum, 10-lobed. Calyx thick, 
teeth very unequal; 2 superior quite connate; lowest longer than 
the others or about equal to superior. Corolla usually large;
