262 NATURAL HISTORY OF PLANTS. 
64. Gliricidia H. B. K—Receptacle cupuliform or shortly obco- 
nical, lined by a concave disk not produced round gyneceum. Calyx 
gamosepalous, either nearly entire and evenly truncate, or oftener 
very shortly 5-toothed; 2 superior teeth sometimes subconnate. 
Standard large reflexed, without callosities; claw articulated at base ; 
limb bare or furnished with small inflexed auriculate appen- 
dages; wings’ falcate-oblong free; keel curved obtuse. Stamens 
10, 2-adelphous (9-1); anthers uniform; connective long ovate, 
often coloured. Germen stipitate o-ovulate; style curved or inflexed, 
glabrous or furnished with small hairs below stigma ; stigma terminal 
small or minutely capitate. Legume stipitate, broadly linear plano- 
compressed, sometimes unequally constricted between seeds, con- 
tinuous within, 2-valved ; valves coriaceous thick. Seeds exarillate. 
—Trees or shrubs ; leaves imparipinnate ; leaflets exstipellate, rather 
large, quite entire, reticulate penniveined, often spotted; stipules 
small ; flowers’ (sometimes appearing before the leaves) in racemes 
inserted in axils or at old defoliated nodes; bracts and bractlets 
small or 0 (Zropical America’). 
65. Diphysa Jacq.’—Receptacle slightly concave, lined by a disk. 
Calyx gamosepalous; lobes 5, unequal; 2 superior broader obtuse ; 
lowest longer and narrower than remainder, very acute, arched. 
Standard unguicalate suborbicular, with 2 callosities within ; wings 
curved oblique; keel curved, more or less acute or beaked. Stamens 
10, 2-adelphous (9-1); anthers uniform. Germen stipitate oo-ovu- 
late arched, continuous with curved subulate glabrous style ; stigma 
small or minutely capitate, terminal. Legume stipitate elongated ; 
endocarp linear subplane, much narrower within, scarcely or not 
hollow between seeds; sutures linear bare, either scarcely prominent, 
or produced longitudinally into a subulate keel; exocarp separable 
from endocarp, inflated and dilated at each face into a reticulated, 
vesicular or compressed keel-like membrane. Seeds ovate or oblong, 
more rarely transversely elongated compressed.—Shrubs or trees, 
often glandular; leaves imparipinnate; leaflets entire exstipellate
