Subtribe 7. CORYNELLANAE. Shrubs or trees, with abruptly pinnate 

 leaves. Flowers in axillary small racemes or fascicled on short axillary 

 branches. Calyx campanulate, the tube as broad as long or nearly so, the 

 lobes minute. Banner suborbicular to obovate, short-clawed, more or less 

 reflexed. Wings short-clawed, with oblong or obliquely oblanceolate blades, 

 distinct, usually with small basal auricles. Keel-petals similar, often broader, 

 usually more lunate, their blades united from the middle to or nearly to the 

 tip. Stamens diadelphous, the staminal sheath not more dilated below, 

 straight, the upper filament free, straight. Style glabrous. Pod 2-valved, 

 flat, linear, sessile or short stipitate, sometimes slightly torulose, but neither 

 with cross-partitions, nor breaking up into joints. Seeds from orbicular to 

 reniform, somewhat flattened, without a funicle. 



Style not bearded, more or less arcuate; calyx -lobes very short. 



Calyx truncate, with 5 minute lobes, of which the upper two are close 

 together; banner orbicular. 

 Stigma subterminal under the strongly hooked and more or less flattened 



tip Of the style; leaf-rachis not winged. 15. CoRYNELLA. 



Stigma terminal at the end of the curved but scarcely hooked style. 

 Rachis of the leaves not winged; keel broad, strongly arcuate, not 



exceeding the banner in length, the blades nearly semicircular. 14. Sabinea. 



Rachis of the leaves distinctly wing-margined; keel narrower, less 



arcuate, longer than the banner. 16. Notodon. 



Calyx 2-lipped; banner obovate; style bent at the base, thereafter nearly 



straight; petals subequal; rachis winged. 17. Bembicidium. 



Style bearded along the upper margin, bent at the base; calyx-lobes prominent,

14. SABINEA DC. Ann. Sci. Nat. 4: 92. 1825. 



Trees or shrubs. Leaves abruptly pinnate, with stipules and sometimes with minute 

 stipels. Flowers purplish, in small fascicles or short racemes in the axils of old leaves, ap- 

 pearing with or before the new leaves; bracts small; bractlets none. Calyx open-campanulate 

 or turbinate, as broad as high, truncate, with 5 minute lobes. Banner broad, short-clawed, 

 spreading or reflexed. Wings short-clawed; blades oblong or oblanceolate, slightly falcate,
