338 PENNELL: PLANTS OF SOUTHERN UNITED STATES 
Cracca onobrychoides (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, 4189. Its specific status is here proposed tentatively. 
Specimens of C. onobrychoides 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 (E. 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,
