/Schks has given an excellent fig. of this species. . The 
plant resembles C. scoparia in the colour of its spikes, but 
its fruit is very different. It is oftener confounded with C. 
a from which however its characters clearly — 
te it. 
wThe C. albolutescens Schw. An. Tab. seems to be only a 
variety of the common C€. straminea. On the specimens from 
hio, is to. be seen the eiarpcteriatic broad wing- 
ed fruit. Preiss

This ae differs in the shorter ovate fruit, with a very 
short beak, and hence more nearly round, compressed like the 
other. The = are also smaller, more distinctly ovate. 
Grows with the other—also in Missouri. It was this variety 
which was described by Willd, and to which the name was 
given. Muh. as well as Schk: refer both the figs. in Schk., 
with propriety, to the same species.
