98 PULSE FAMILY. 



4. Herbs, irith abruptly pinnate leaves, the common petiole terminated by a tendril, 

 by which t/ie plant climbs or supports itstlf, or in many loio species the tendril 

 reduced to a mere bristle or tip. or in Cicer, which has toothed leaflets, an odd 

 leajlet commonly tikes its place : peduncles axillary : stamens almost always 

 diadelphous. Cotyledons veiy thick, so that they remain underground in germi- 

 nation, as in the Pea. 



* Leaflets entire or sometimes toothed at the apex : radicle bent on the cotyledons : 



style mflexed: podjtat or flattish. 



40. PISITM. Lobes of the calyx leafy. Style rigid, dilated above and the margins 



reflexed and joined together so that it becomes flattened laterally, bearded 

 down the inner edge. Pod several-seeded: seeds globose. Flowers large. 

 Leaflets only 1-3 pairs. 



41. LATHYRUS. Lobes of the calyx not leafy. Style flattened above on the 



back and front, bearded down one face. Pod several-seeded. Seeds some- 

 times flattish. Leaflets few or several pairs. 



42. VI CIA. Style slender, bearded or hairy only at the apex or all round the upper 



part. Pod 2 - several-seeded. Seeds globular or flattish. Leaflets few or 

 many pairs. 



43. LENS. Lobes of the calyx slender. Style flattish on the back, and minutely 



bearded down the inner face. Pod 1 - 2-seeded. Seeds flattened, lenticular. 

 Flowers small. 



* * Leaflets toothed all round, and usually an odd one at the end in place of a ten- 



dril: style incurved, naked: radicle of the embryo almost straight. 



44. CICER. Calyx 5-parted. Pod turgid oblong, not flattened, 2-seeded. Seeds 



large, irreguiarly rounded-obovate, pointed. Peduncle mostly 1-flowered. 



B. Stamens separate to the base. (Plants not twining nor climbing.) 

 1. Leaves simple or of 3 digitate leaflets. 



45. CHORIZEMA. Somewhat shrubby, with simple and spiny-toothed leaves, 



scarcely any stipules, and orange or copper-red flowers. Standard rounded 

 kidney-shaped: keel straight, much shorter than the wings. Pod ovoid, 

 turgid, several-seeded. 



46. BAPTISI A. Herbs, with simple entire sessile leaves and no stipules, or mostly 



of 3 leaflets with deciduous or persistent stipules. Flowers yellow, blue, or 

 white. Standard erect, with the sides turned back, about equalled by the 

 oblong and straightish wings and keel. Pod inflated, coriaceous, stalked iu 

 the calyx, many-seeded. 



47. THERMOPSIS. ' Pod scarcely stalked, linear, flat. Otherwise as Baptisia. 



2. Leaves odd-pinnate. 



48. CLADRASTIS. Trees,J*ith large leaflets, no obvious stipules, and hanging 



terminal panicles of white flowers. Standard turned back: the nearly sep- 

 arate straightish keel-petals and wings oblong, obtuse. Pod short-stalked in 

 the calyx, linear, very flat, thin, marginless, 4 - 6-seeded. Base of the petioles 

 hollow and covering the axillary leaf-buds of the next year. 



49. SOPHORA. Trees, shrubs, or herbs, with numerous leaflets, and mostly 



white or yellow flowers in terminal racemes or panicles. Keel-petals and 

 wings oblong, obtuse, usually longer than the broad standard. Pod com- 

 monly stalked in the calyx, terete, several-seeded, fleshy or almost woody, 

 hardly ever opening, but constricted across into mostly 1-seeded portions. 



II. BRASILETTO FAMILY. Flowers more or less irregu- 

 lar, but not papilionaceous : when they seem to be so the petal 

 answering to the standard will be found to be within instead of out- 

 side of the other petals. Stamens 10 or fewer, separate. The 

 leaves are sometimes twice pinnate, which is not the case in the 

 true Pulse Family. Embryo of the seed straight, the radicle not 

 turned against the edge of the cotyledons. 



1. Leaves simple and entire. Corolla appearing as if papilionaceous. 

 60. CERC1S. Trees, with rounded heart-shaped leaves, minute early deciduous 

 stipules, and small but handsome red-purple flowers in umbel-like clusters on 

 old wood, earlier than the leaves, rather &cid to the taste. Calyx short,
