338 Pennell: Plants of southern United States 



Cracca onohrychoides (Nutt.) Kuntze as it occurs in central and 

 western Arkansas and eastern Oklahoma is relatively a stout plant, 

 its stem and leaf-rhachises hirsute with more or less spreading 

 rusty hairs, its leaflets mostly nine to twelve pairs, elliptic-oblong, 

 densely and softly pubescent beneath. The plant here considered, 

 for which is taken up Featherman's name, is more slender, its stem 

 and leaf-rhachises shortly pubescent with appressed or but slightly 

 spreading hairs, giving by their more scattered position the effect 

 of being less rusty, its leaflets six to nine pairs, linear-oblanceolate. 

 This is probably a characteristic plant of the long-leaf pine-land in 

 Louisiana and Mississippi; we have it from Gulfport, Harrison 

 County, Mississippi, < September 8, 1900, F. E. Lloyd &" S. M. 

 Tracy 161, and from open pine-land, one to two miles north of 

 Abita Springs, St. Tammany Parish, Louisiana, < August 14, 

 1912, 418Q. Its specific status is here proposed tentatively. 

 Specimens of C. onohrychoides collected on prairies in Bowie 

 County, Texas, in 1898, H. Eggert,and at Hempstead, Waller 

 County, Texas, E. Hall 119, in pubescence and leaf-form show pos- 

 sible first stages of transition toward C. angustifolia. The plant 

 needs further field-study. 



Eysenhardtia texana Scheele 



The single species of Eysenhardtia occurring through most of 

 central southern Texas is this, based upon Lindheimer's collection 

 at New Braunfels, Texas. It has been confused with the central 

 Mexican E. polystachya (Ortega) Sargent (£. amorphioides H.B.K.), 

 but is a smaller plant, a shrub rather than a small tree, its leaflets 

 fewer in number, finely puberulent rather than pubescent, its 

 calyx-tube split on posterior side relatively more deeply and its 

 legumes smaller, evidently upcurved, at maturity ascending, not 

 reflexed. Mr. W. E. Safford and the writer are planning a revision 

 of this small but neglected genus. On black calcareous soil, 

 Edwards Plateau, northwest of New Braunfels, Comal County, 

 Texas, > September 14, 1913, 5468.
