256 NATURAL HISTORY OF PLANTS. 



slightly adherent to keel; keel curved obtuse. Stamens 10, scarcely 

 perigynous, 1-adelphous below; anthers uniform or 5 oppositipe- 

 talous a little shorter. Germen sessile co-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 [Southern 

 Europe, Western Asia). 



53? Ptychosema Benth. 1 — "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 cc -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, 2 bracts 1, 2, at articulation 

 on base of pedicel, bractlets 2 in middle of pedicel" {South-Western 

 Australia 3 ). 



54. Barbieria DC. 4 — 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 (U-l) ; filaments 

 finally free, very slender, anthers uniform ; connective glandular. 

 Germen sessile cc -ovulate; style long slender, longitudinally bearded 

 within, very shortly curved below apex ; summit slightly dilated, 

 stigmatiferous. Legume linear straight piano-compressed, trans-
