116 PEA FAMILY (PULSE FAMILY) 



not longer than the leaves, and the seedpods, about one 

 inch long, are nearly smooth at maturity. The prostrate 

 or twining G. mollis has hairy foliage and seedpods, and 

 bears bright rose-purple flowers at the top of the flowering- 

 stalks, which are longer than the leaves. 



Butterfly Peas (Genera Clitoria and Bradhurya) 



The largest of our butterfly peas, Clitoria mariana, is 

 common in dry soil in many localities. The long standard 

 is curved outward, displaying narrow lines of magenta and 

 a blotch of pale yellow that mark its delicately colored 

 wide expanse. The exotic C. Ternatea, with blue flowers, 

 and five-foliate leaves, is an attractive vine that sometimes 

 escapes from cultivation. 



The spurred butterfly peas, Bradhurya, are easily dis- 

 tinguished from the former, as the flowers are shorter and 

 more round in form, and on the back of the standard, near 

 the base, show a short, blunt spur. 



Clitoria mariana. Flowers lilac or pale blue, 2 in. long, 

 solitary or few from leaf-axils. Pods about 1 in. long. Stems 

 1-4 ft. long, erect or twining. Leaflets 3, 1-2 in. long. Dry 

 soil. Blooming in spring and summer. Fla. to N. Y., Texas, 

 and Mo. 



Bradhurya arenicola (Centrosema). Flowers lilac or pale 

 blue, about 1 in. long, standard usually broader than long. 

 Upper calyx lobes shorter than lower. Pods narrow, 3-5 in. 

 long. Twining vine, leaflets 3, broadest near base, 1-2 in. 

 long. Dry soil. Blooming from spring to fall. Fla. 



Bradhurya virginica. Flowers similar to above species. 

 Calyx lobes nearly equal in length. Leaflets more nearly 

 oblong or linear. Sandy soil. Fla. to N. J., Texas, and Ark. 



Groundnut {Apios tuherosa) 



This attractive twining vine, found in thickets from 

 Florida northward, has leaves of five or seven leaflets, and
