426 LEGUMINOUS PLANTS. 



CLITORIA MARIANA, I*~(Butterfly pea). 



A low, ascending or twining plant, with pinnately, 3 folialate leaves, 

 and very large, pale blue flowers, July. Eatable, but too scattering. 



CENTROSEMA VIRfUNIANUM, Benth- (Spurred Butterfly 



Pea). 



Corolla much like in the foregoing, but the spreading standard with a 

 spur shaped projection on the back near the base; pod long and linear, 

 many seeded, thickened at the edges A twining perennial, with 3 fol- 

 iolate stipulate leaves, and large, showy flowers. Corolla 7 inches long, 

 violet. Common. Forage plant. Flowers all summer. 



AMPHICARP-S1A MONOICA, ^Yl- (Hog pea nut). 



Flowers of two kinds; those of the racemes from the upper branches 

 perfect, but seldom ripening fruit; those near the base and on creeping 

 branches with the corolla none or rudimentary, ana few free stamens, 

 but fruitful, calyx about equally 4 (rarely 5) toothed; bractlets none, 

 or minute; keel and wing petals similar, almost straight, the standard 

 partly folded round them. Stamens diadelphous; style beardless; pods 

 of the upper flowers when formed somewhat scymetar-shaped, 3-4 seed- 

 ed ; of the lower ones commonly subterranean, obovate or pear shaped, 

 fleshy; ripening usually but one large seed. A low and slender peren- 

 nial, the twining stems clothed with brownish hairs; leaves pinnately 

 3-foliolate; leaflets rhombic, ovate, stipulate. Flowers small, in clus- 

 ters, or compound racemes, purplish. The subterranean pods are hairy 

 and greedily eaten by hogs. The herbage makes very good food. The 

 fruit burrowing habit of this species is very similar to that of the Afri- 

 can pea nut. It abounds round Nashville, and requires rich soil in the 

 woods. Flowers all summer. 



GALACTIA MOLLIS, R. TZrown~(Milk Pea).

 downy and hairy beneath; flowers in interrupted or somewhat knotty 

 racemes, purplish, pods very downy; flowers in summer. 



GALACTIA GLABELLA, Michx.--(moo*A Milk Pea). 



Stems nearly smooth, prostrate; leaflets elliptical or ovate, oblong, 

 sometimes slightly hairy beneath; racemes short, 4-8 flowered; pods 

 somewhat hairy; flowers large, rose-purple. They are what their name 

 indicates, excellent food for milk cows. Abundant in the State.
