256 NATURAL HISTORY OF PLANTS. 
slightly adherent to keel; keel curved obtuse. Stamens 10, scarcely 
perigynous, l-adelphous below; anthers uniform or 5 oppositipe- 
talous a little shorter. Germen sessile -ovulate; style subulate 
curved beardless ; apex scarcely capitate, stigmatiferous. Legume 
linear, rather acute, terminated by style, continuous within, 2-valved ; 
valves thin, obliquely striated, finally twisted. Seeds transversely 
oblong, attached by middle, exarillate; embryo exalbuminous ob- 
long; radicle thick cylindrical, much inflexed—Herbs, perennial 
glabrous, erect or bent, usually branched; leaves alternate impari- 
pinnate; leaflets entire veined; stipules semi-sagittate or unsym- 
metrical, sometimes leaf-like; flowers in terminal and axillary 
racemes; bracts narrow, usually persistent; bractlets 0 (Southern 
Europe, Western Asia). 
53? Ptychosema Bentu.'—“ Calyx turbinate ; lobes nearly equal 
in length; 2 superior connate into a truncate emarginate lip. 
Petals with rather long claws; standard suborbicular emarginate ; 
wings falcate oblong free ; keel shorter than wings, almost straight, 
obtuse. Stamens all connate into a sheath cleft above; anthers 
uniform. Germen sessile «-ovulate, style short inflexed; stigma 
extrorse oblique. Legume... . ?—A herb, small, diffuse, nearly 
glabrous; leaves imparipinnate; leaflets quite entire, parallelly 
penniveined on under surface, exstipellate; stipules small; pe- 
duncles (always?) terminal, 1-flowered,’ bracts 1, 2, at articulation 
on base of pedicel, bractlets 2 in middle of pedicel” (South-Western 
Australia’). 
54. Barbieria DC.‘—Calyx long tubular; lobes acute nearly 
equal. Petals very unequal ; standard much elongated, subsessile, 
narrowed at base; wings and keel (rather longer than wings) fur- 
nished with long claws. Stamens 10, 2-adelphous (9-1); filaments 
finally free, very slender, anthers uniform; connective glandular. 
Germen sessile o-ovulate; style long slender, longitudinally bearded 
within, very shortly curved below apex; summit slightly dilated, 
stigmatiferous. Legume linear straight plano-compressed, trans-
