90 LEGUMINOS^E. (PULSE FAMILY.) 



18. LESPEPEZA. Stamens diadelphous (9 & 1) : anthers uniform. Pod 1 - 2-jointod. Flow- 



ers often of 2 sorts, the more fertile ones apetalous. Leaflets not stipellate. 



19. 8TYLOSANTHES. Stamens monadclphous : antliers of 2 forms. Pod 1 - 2-jointed. Flow- 



ers of 2 sorts intermixed, the fertile apetalous. Leaflets not stipellate. 



TRIBE HI. VICIEJE. Stamens diadelphous (9 & 1). Pod continuous, 1-oelled. Coty- 

 ledons very thick and fleshy (as in a pea), not rising to the surface, but remaining under 

 ground in germination. Herbs, with abruptly pinnate leaves, the common leafstalk 

 produced into a tendril or bristle. Peduncles axillary. 



20. VICIA. Stylo filiform, bearded round the apex, or down the side next the keel-petals. 



21. LATIIYKUS. Style flattened, bearded on the side towards the standard. 



TRIBE IV. PHASEOLEJE. Stamens more or less diadelphous (9 & 1). Pod contin- 

 uous, not jointed, nor more than 1-celled, except by cellular matter sometimes deposited 

 between the seeds, 2-valved. Cotyledons thick and fleshy, usually rising to the surface, 

 but remaining nearly unchanged (as in a bean, seldom foliaceous) in germination. 

 Twining or trailing plants, with pinuately 3-foliolate, rarely 5 - 7-foliolate leaves, mostly 

 stipellate, destitute of tendrils. Flowers often clustered in the racemes. 

 * Keel spirally twisted. Cotyledons thick, nearly unchanged in germination. 



22. PHASEOLUS. Keel spiral. Leaves 3-foliolat, stipellate. 



23. APIOS. Keel incurved, at length twisted. Leaves 5 - 7-foliolate, not stipellate. 



* * Keel straight. Cotyledons not so thick. 

 +- Ovary 1 - 2-ovuled. Leaflets not stipellate. Flowers yellow. 



24. RHYNCHOSIA. Calyx 4-left, somewhat 2-lipped, or 4-parted. Pod 1 - 2-seeded. 



i- - Ovary several ovuled. Leaflets usually stipellate. Flowers not yellow. 

 26. GALACTIA. Calyx 2-bracteolate, 4-cleft, the upper lobe broadest and entire. Bracts 

 deciduous. 



26. AMPHICARP-SIA Calyx not bracteolate, 4 - 5-toothed. Peduncles many-flowered. 



Bracts persistent. 



27. CLITOKIA Calyx 2-bracteolate, tubular, 6-cleft. Peduncles 1 - 3-flowered. 



28. CENTROSEMA. Calyx 2-bracteolate, short, 6-cleft. Peduncles few-flowered. Standard 



with a spur at its base. 



TRIBE V. SOPHOREJE and PODALYRIEJE. Stamens 10, distinct 



29. BAPTISIA. Calyx4-6-lobod. Keel-petals distinct. Pod inflated. Herbs. Leaves pal- 



mately 3-foliolate or simple. 



80. CLADRAST1S. Calyx 5-toothed. Keel-petals distinct. Pod very- flat. Tree, with pin- 



nate leaves. 



SUBORDER II. C^SALPINIE^). THE BRASILETTO FAMILY. 



Corolla imperfectly or not at all papilionaceous, sometimes nearly regu- 

 lar, imbricated in the bud, the upper or odd petal inside and enclosed by 

 the others. Stamens 10 or fewer, commonly distinct, inserted on the calyx. 

 Seeds anatropous. Embryo usually straight. 



* Flowers imperfectly papilionaceous, perfect. 



81. CERCIS. Calyx campanulate, 5-toothed. Pod flat, wing-margined. Leaves simple. 



* * Flowers not papilionaceous, perfect. 



82. CASSIA. Calyx of 5 n^arly distinct sepals. Leaves simply pinnate. 



* * * Flowers not at all papilionaceous, not perfect. 



83. GYMNOCLADUS. Flowers dioecious. Petals 5, regular, inserted on the summit of the 



tubular-funnel-form calyx. Stamens 10. Leaves doubly pinnate. 



84 GLEDIT^CIIIA. Flow-era polygamous. Petals, divisions of the open calyx, and staim-ns 

 8-5. Leaves 1-2-uincAte.
