234 NATURAL HISTORY OF PLANTS. 
much thickened and bearing inflexed auriculate appendages at: base ; 
wings long obovate free; keel obovate; apex beaked, subspirally 
twisted. Stamens 10, 2-adelphous (9-1); vexillary stamen genicu- 
late and appendiculate a little above base ; anthers uniform. Germen 
shortly stipitate, surrounded at base by a disk produced into a 
conical, unevenly furrowed, usually 10-crenate sheath ; 2-3-ovulate ; 
style very long, gradually thickened within and twisted with beak 
of keel, at apex tapering and longitudinally bearded along posterior 
margin; summit capitate subglobose, bearing stigmatic papille ; 
back furnished with an uneven triangular and vexilliform compressed 
(not hollow) appendage below summit. Legume broadly linear, 
rather compressed, biconvex, thinly stuffed within between seeds, 
2-valved. Seeds 1-3, oblong, half surrounded by long linear hilum, 
exarillate ; outer coat coriaceous thick glabrous; embryo thick sub- 
ovoid.—A high twining herb, suffrutescent at base; leaves and 
axillary inflorescences of Phaseolus; bracts minute caducous 
(Tropical Africa). See p. 198. 
10. Dolichos L.’—Flowers of Phaseolus; calyx subcampanulate ; 
lobes obtuse; 2 superior connate into one, emarginate or entire. 
Standard thickened, and bearing inflexed auriculate appendages at 
base; wings adhering to keel; keel curved, usually beaked (not 
spirally twisted). Germen subsessile, «-ovulate ; style slightly thick- 
ened above, often rather compressed, and longitudinally bearded below, 
terminal or subterminal (not capitate) stigma, or penicillate at sum- 
mit. Legume falcate or linear, more rarely rather broad and much 
compressed (Ladlaé*); sutures often thickened; valves 2, flat or 
convex. Seeds thick or compressed; hilum short or elongated, 
dilated with a linear rather fleshy aril—Herbs or undershrubs, twin- 
ing erect or prostrate ; leaves pinnate; 3-foliolate stipellate ; stipules 
small or gland-like ; flowers’ solitary or fascicled, axillary, usually in 
axillary racemes ; fascicles 1—©-flowered each in axil of a bract ;
