138 LEGUMLNOS.&. (PULSE FAMILT.) 



* * Flowers all alike and perfect, in close spikes or heads : corolla whitish or cream- 

 color with a purple spot on the standard, about the length of the downy calyx : 

 stems upright, wand-like (2° -4° high). 



5. L. hirta, Ell. Peduncles longer than the leaves; petioles slender; leaflets 

 roundish or oval, hairy ; spikes cylindrical, rather loose ; pods nearly as long as 

 the calyx. (L. polystachia, Michx.) — Dry hillsides. 



6. L. capitata, Michx. Peduncles aiid petioles short ; stems rigid, woolly; 

 leaflets elliptical or oblong, thickish, reticulated and mostly smooth above, silky 

 beneath; spikes or heads short; pods much shorter than the calyx. — Varies 

 greatly, most of all in var. angustif6lia : slender; leaflets linear; peduncles 

 sometimes elongated. — Dry and sandy soil; the narrow variety only found 

 near the coast and southward. 



21. STYLOSANTHES, Swartz. Pencil-Flower. 



Calyx early deciduous ; the tube slender and stalk-like ; the limb unequally 

 4-5-cleft, the lower lobe more distinct. Corolla and monadelphous stamens 

 inserted at the summit of the calyx-tube : standard orbicular : keel incurved. 

 Anthers 10, the 5 longer ones fixed near their base, and the 5 alternate shorter 

 ones fixed by the middle. Style filiform, its upper part falling off after flower- 

 ing, the lower part incurved or hooked, and persistent on the apex of the 1 - 

 2-jointed small and short reticulated pod, the lower joint Avhen present empty 

 and stalk-like. — Low perennials, branched from the base, with wiry stems, 

 pinnately 3-foliolate leaves, the sheathing stipules united to the petiole, no 

 stipe] s, and small, yellow flowers in terminal heads or short spikes. (Name 

 composed of arvXos, a column, and avOos, a flower, from the stalk-like 

 calyx-tube.) 



1. S. elatior, Swartz. Tufted-; leaflets lanceolate, strongly straight-
