266 THE PEA FAMILY. 



long raceme of snow-white blossoms, the standards of which are upright, 

 reflexed and shorter than the other petals, while the keels are large and 

 broad. It grows in sandy soil and from Florida to North Carolina. 



B. tinctbria, yellow, or indigo broom, or horse-fly-weed, is again known 

 by its very small three-foliate glabrous leaves, and its bright yellow flowers, 

 in terminal racemes. It is bushy and spreading and much seen in the 

 Alleghany and Cumberland mountains where it is used about the bridles 

 of horses to keep off annoying flies. In July and August when laden with 

 these bright pea-shaped flowers and hung also with its dull, dark blue cap- 

 sules it is extremely pretty. Later the mountain people collect its roots to 

 use in medicinal ways, as well as its other parts for making domestic dyes. 

 Unless most carefully dried the leaves persistently turn to black. 



B. 7negacdrpa,\\\n\G. possessing the same characteristics of having yellow 

 flowers and three-foliate leaves as Baptisia tinctoria, is a very different indi- 

 vidual and is mostly confined to Florida and Georgia. 



Its oval, or elliptical leaflets are often an inch and a half broad and remain 

 unchanged in colour in drying. They are, moreover, thin, glaucous under- 

 neath, and slightly pubescent. When hung with its numerous capsules the 

 plant is very attractive for they are large, yellowish green and much inflated. 

 At their bases they show the persistent calyx. 



B. perfolidta {Plate LXXX) is a very different looking member of the 

 genus than those others which have gone before ; and confines itself mostly 

 to the sandy district between Georgia and South Carolina. Its simple, per- 

 foliate leaves covered w^ith a bloom, clasp about the stem so closely that 

 they appear almost rounded in outline, and are entire and very thick. From 

 their axils is borne a solitary, yellow flower. It is raised on a peduncle, 

 while the small ovate capsule is lined with deep, lemon-yellow

Most charming and brilliant plants are the lupines and seem to have 

 shown a high sort of intelligence as over sandy barrens they form a sea of
