C> Leaves odd-pinnate : stems twining ; stipels obscure : stipules small, 



28. WISTARIA. Woody, high-climbing, with numerous leaflets, and large showy 



bluish flowers, in hanging terminal dense racemes. Calyx with 2 short teeth 

 on the upper and longer ones on the lower side. Standard large, roundish, 

 turned back : keel merely incurved, blunt. Pod knobby, several-seeded. 



29. APIOS. Herbs, twining over bushes, with 5-7 leaflets, and sweet-scented 



chocolate-purple flowers, in dense and short racemes: peduncles axillary. 

 Calyx with 2 upper very short teeth, and one longer lower one, the side teeth 

 nearly wanting. Standard very broad, turned back : keel long and scythe- 

 shaped, strongly incurved, or at length colled. Pod linear, flat, almost 

 straight, several-seeded. 



i. Leaves of 3 leaflets (pinnately S-foliolate) or rarely one, commonly stipellate. 

 X. Skrubby, (yp from a woody base : wings and sometimes keel small and inconspicuous. 



80. EKYTHRINA. Stem, branches, and even the leafstalks usually prickly. 



Flowers large and showy, usually red, in racemes. Calyx without teeth. 

 Standard elongated: wings often wanting or so small as to be concealed in 

 the calyx; keel much shorter than the standard, sometimes very small. 

 Pod stalked in the calyx, linear, knobby, usually opening only down the 

 seed-bearing suture. Seeds scarlet. 



2. Herbs, mostly twiners, with wings and heel in ordinary proportion. 

 = Flowers not yellow : seeds or at least the ovules several : leaflets stipellate. 



81. PHASEOLUS. Keel of the corolla coiling into a ring or spiral, usually with 



a tapering blunt apex: standard rounded, turned back or spreading. Style 

 coiled with the keel, bearded down the inner side: stigma oblique or lateral. 

 Pod linear or scimetar-shaped. Flowers usually clustered on the knotty 

 joints of the raceme. Stipules striate, persistent. 



82. DOLICHOS. Keel of the corolla narrow and bent inwards at a right angle, 



but not coiling. Style bearded under the terminal stigma. Stipules small' 

 Otherwise nearly as Phaseolus. 



33. GALACTIA. Keel straightish, blunt, as long as the wings: standard turned 



back. Style naked. Calyx of 4 pointed lobes, upper one broadest. Pod flat- 

 tened, mostly linear. Flowers clustered on the knotty joints of the raceme: 

 flower-buds taper-pointed. Stipules and bracts small or deciduous. 



34. AMPHICARP.^A. Keel and very similar wings nearly straight, blunt: the 



erect standard partly folded around them. Style naked. Calyx tubular, 

 4-toothed. Flowers small; those in loose racemes above often sterile, their 

 pods when formed scimetar-shaped and few-seeded ; those at or near the 

 ground or on creeping branches verv small and without manifest corolla, but 

 very fertile, making small and fleshy, obovate or pear-shaped, mostly sub- 

 terranean pods, ripening one or two large seeds. Bracts rounded and per- 

 sistent, striate, as are the stipules. „. ^. . . a a 



86 CENTROSEMA. Keel broad, incurved, nearly equallmg the wmgs: standard 

 laree and rounded, spreading, and with a spur-like projection behind. Calyx 

 short 6-cleft. Style bearded only at the tip around the stigma. Pod long, 

 linear with thickened edges bordered by a raised line on each side. 1 lowers 

 showv. Stipules, bracts, and bractlets striate, persistent. , , , , 



86. CLITO'RIA. Keel small, shorter than the wings, incurved, acute: standard 



nies, bracts, and bractlets persistent, striate. . ^, . . j 



87 HARDENBERGIA. Keel small, much shorter than the wings, mcurved, 



blunt : i^tandard large in proportion, rounded, spreading. Calyx short 

 s'toothed, the 2 uppir teeth united. Style short, naked. Pod linear, not 

 bordered. Flowers rather small, in racemes. Stipules and bracts small, 

 striate, mostly deciduous. Leaflets mostly single. 



88 KENNEDYA. Keel incurved, blunt or acute, mostly equalling or exceeding 



the wings: standard broad, spiearling. Calyx 5-lobed: 2 upper lobes pardy 

 united. Style naked. Pod linear, not bordered. Flowers showy, red, smgle 

 or few on the peduncle. Bracts and stipules striate. 

 =i = Flowers yellow {sometimes purple-tinged outside ) : ovules only 2: podl- i-seeded. 

 sq EHYNCHOSIA. Keelof the corolla incurved at the apex: standard spreading: 

 89. RHYN^»':^^5'.^„t,d „ lobed. Pod short and flat. Flowers small Leave, 

 mos'tly soft-downy and resinous-dotted, sometimes of a smgle leaflet.
