Plante Lindheimeriane. 917 
lelis semine multo minoribus: cst. F. radiate sed fructu mi- 
nore. — Thickets in light soil, near San Antonio, New 
Braunfels, &c. March. This, Dr. Engelmann, probably 
with good reason, considers as distinct from the F. radiata 
with glabrous fruit (the form that alone occurs around St. 
Louis.) “ The fruit is not only much smaller and more slen- 
der than that of F. radiata, but the proportion of the empty 
cells is different ; these being much smaller than the seed ; 
while in the former they are about equal, and in F. carinata 
(which has a different habit) larger. Cauline leaves often 
deeply dentate at the base, or almost pinnatifid, but some- 
times entire.” Engeim.!
