florum. D. distichum, Geyer, Ms.; glabrum, foliorum seg- 
mentis latioribus minus divaricatis. 
Has. Slopes of the undulating plains between Kanzas and 
Platte Rivers, with Œnothera serrulata, (n. 163.)— Var. 
Grassy stony borders of rivulets, high plains of Spokan and 
Nez Percez, (n. 420.)—Our D. simplex, Messrs. Torrey and 
Grey unite with D. Menziesii; probably with justice, for 
it is as difficult to define the limits of the American species - 
of this Genus as of the European ones. Again, it must be 
allowed that the var. here given of D. simpler has a 
very different appearance from that species, in its gla- 
brous leaves, with broader, shorter, and blunter laciniæ, 
and (according to Geyer) regularly distichous flowers: 
—yet I fear there are no permanent distinguishing cha- 
racters.
