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. Gerrnen 

 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 papillae ; 

 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). Seep. 198. 



10. Dolichos L. 1 — 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, oc-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 {Labia If) ; 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 3 solitary or fascicled, axillary, usually in 

 axillary racemes ; fascicles 1- oo- flowered each in axil of a bract ;
