PULSK FAMILY. P7 



C. Leaves odd-pinnate : stems immng : stipels obtcure : 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. 1'od 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 axillarv. 

 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 scy*.he- 

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

 straight, several-seeded. 



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

 1. Shrubby, or from a woody base : wings and sometimes keel, smnll and inconspicuous- 



30. ERYTHRINA. 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 keel in ordinary proportion. 

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



31. 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. 



32. 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 \fings: 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^EA. 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 very small and without manifest corolla, but 

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

 terranean pods, ripening 0113 or two large seeds. Bracts rounded and per- 

 sistent, striate, as are the stipules. 



35. CENTROSEMA. Keel broad, incurved, nearly equalling the wings: standard 



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

 short, 5-cleft. Style bearded only at the tip around the stigma. Pod long, 

 linear, with thickened edges bordered by a raised line on each side. Flowers 

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



36. CLITORIA. Keel small, shorter than the wings, incurved, acute: standard 



much larger than the rest of the flower, notched at the end, erect. Calyx 

 tubular, 5-toothed. Style bearded down the inner side. Pod oblong-linear, 

 flatfish, not bordered. 'Flowers large and showy, 1 - 3 on a peduncle. Stip- 

 ules, bracts, and bractlets persistent, striate. 



37. HARDENBKRGFA. Keel small, much shorter than the wings, incurved, 



blunt : standard large in proportion, rounded, spreading. Calyx short, 

 5-toothed, the 2 upper teeth united Style short, naked. Pod linear, not 

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

 striate, mostly deciduous. Leaflets mostly single. 



38. KENNEDYA. 'Keel incurved, blunt or acute, mostly equalling or exceeding 



the wino-s: standard broad, spreading. Calyx 5-lobed: 2 upper lobes partly 

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

 or few on the peduncle. Bracts and stipules striate. 

 = = Flowers yellow (sometimes purple-tinged outside ) : ovules only 2 : pod 1 - 1-seeded. 



39. RHYNCHOSIA. Keel of the corolla incurved at the apex: standard spreading. 



Calyx 4-5-parted or lobed. Pod short and flat. Flowers small. Leaves 

 mostly soft-downy and resinous-dotted, sometimes of a single leaflet.
