238 NATURAL HISTORY OF PLANTS. 
18. Calopogonium Dusvx.—Flowers almost those of Galactia ; 
2 superior calyx-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 o-ovulate; style slender 
beardless; apex capitate stigmatiferous. Legume linear plano-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,” 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® (South and Central America’). 
19. Mastersia Benru.’—“ 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 «-ovulate ; style short, filiform curved, beardless ; 
stigma terminal capitate.” Legume oblong-linear plano-compressed 
indehiscent ; superior suture slightly winged. Seeds o, 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’ 
(Assan). 
20. Erythrina L.’—Receptacle cupuliform, lined by adisk; disk 
Bras., Papil., 159, t. 42, fig. 2. This genus has 
much affinity, on the one hand, with Grona and 
Calopogonium, by the free vexillary stamen; on 
the other, with Camptosema, but differs from the 
latter by its stamens, by its compressed apiculate 
fruit, thinly stuffed between the seeds, and by 
the habit of its hilum.

3 This genus differs from Galactia by its 
calyx, from Glycine by its nodose-racemose 
inflorescence.

6 «This genus is by its habit allied to some 
species of Dioclea and Pueraria, while by its 
stamens it is distinct from them, and by its 
legume anomalous among Phaseolee” (BENTH.),
