LEGUMINOSZ-PAPILIONACEA. 275 
solitary on terminal, axillary (always?) peduncle; bracts and bract- 
lets minute, very caducous” (Australia). 
89. Astragalus T.’—Receptacle cupuliform, glandular within ; 
mouth horizontal or slightly oblique. Calyx tubular or more or less 
inflated, gamosepalous to a considerable height; teeth or lobes 
short, nearly equal. Petals usually rather long unguiculate ; standard 
erect long, ovate obovate or panduriform; wings unevenly oblong ; 
limb often with auriculate appendages above at base; keel equal to 
or a little shorter than wings and more or less adherent to them by 
its outer edges, of variable form, obtuse. Stamens 10, 2-adelphous ; 
9 connate into a sheath cleft above; vexillary stamen free; anthers 
uniform. Germen sessile or stipitate; ovules o, 2-seriate, more or 
less descending ; style slender, straight or curved, beardless ; stigma 
minute terminal. Legume sessile or stipitate, finally 2-valved, very 
variable in form ; sometimes longitudinally divided by intrusion of 
dorsal suture into 2 spurious cells; sometimes turgid or membranous 
inflated, imperfectly or more rarely perfectly (Phaca,’? Lrophaca’) 
divided within. Seeds campylotropous exarillate funiculate.—Small 
shrubs, densely branched,‘ unarmed or bristling with spinescent 
hardened petioles; or oftener undershrubs or herbs; leaves either 
imparipinnate, or almost abruptly pinnate with persistent petiole, 
sometimes digitate 3-foliolate,’ sometimes 1-foliolate; leaflets entire 
exstipellate ; stipules free or adnate to petiole, more rarely connate 
into one oppositifolious ; flowers’ solitary or more rarely umbellate’ or 
oftener racemose or spicate ; inflorescences often pedunculate, axillary 
or springing laterally from stem ; bracts usually minute; bractlets 
small or minute (Lurope, northern and subtropical Asia, Africa, and
