1. Tephrosia virginiana (L.) Pers. (Cracca virginiana L.) Smooth- 

 leaflet Virginia Goatrue. Map 1229. Infrequent but usually in colonies 

 where it is found. In southern Indiana it is found on the crests of chestnut 

 oak and black oak ridges and on sandstone outcrops. In northern Indiana 

 it is found in very dry, sandy soil on black oak land and was formerly 

 common on the low dunes about Lake Michigan. It is also found on sandy 

 hills in the open or in open woodland in northwestern and southwestern 

 Indiana. The habitats of the species and the following variety are the 

 same and it is probable that their range is co-extensive. My attention had 

 not been called to the variety before I undertook to write the genus. Since 

 I usually collect only one specimen from a county, the maps do not ac- 

 curately represent the distribution of the two forms. I have seen speci- 

 mens of this form from the following states: Ala., Ark., D. C, 111., Ind., 

 Ky., Mich., Mo., N. C, N. J., Okla., Pa., S. C, Tenn., Tex., Va., and W. Va. 



la. Tephrosia virginiana var. holosericea (Nutt.) T. & G. Hairy- 

 leaflet Virginia Goatrue. Map 1230. Habitat and distribution as dis- 

 cussed under the preceding species. I have seen specimens from the fol- 

 lowing states: Ark., Ill, Ind., Kans., Mass., Md., Mich., N. C., N. J., 

 N. Y., Ohio, Okla., R. I., S. C., Va., Wis., and W. Va. 



3722. WISTERIA Nutt. 



Leaflets mostly 9, ovate or elliptic-ovate to lance-elliptic, 3-7 cm long; racemes 15-35 

 cm long, not dense; pedicels about 10 mm long; lower teeth of calyx at least half 

 as long as the tube; spur of wings of corolla about as long as the claw; pods 7-12 

 cm long, glabrous 1. W. macrostachya. 



Leaflets 9-15, elliptic-ovate to oblong or oblong-lanceolate, 2-5 cm long; racemes 4-10 

 cm long, dense; pedicels about 5 mm long; lower teeth of calyx less than half as 

 long as the tube; spur of wings of corolla much shorter than the claw; pods 5-10 

 cm long, glabrous. (See excluded species no. 393, p. 1066.) W. frutescens.
