C. lanuginosa, Mx. ? 
This plant is very well described by Muh. But as the 
works of Pursh and Eaton are most accessible by the stu- 
dent, and as it is placed by them in a subdivision to wh 
it will not often be found to belong, this species is very 
liable to be mistaken. The subdivision in Ph., terminal 
spikes staminate, the rest andro ous, is contradicted by 
the description of every species under it. It should be, 
terminal spike staminate below, the others pistillate, and the 
subdivision would then include all the species except U. 
trichocarpa. ‘This species should be removed to the last . 
subdivision in Ph. and Eaton, staminate spikes several ; and 
the specific description of C. trichocarpa should be amend- 
ed by the character, staminate spikes sometimes pistillate at 
the apex. Pursh indee fom Schk., 
and in the figs. of Schk. the plant corresponds to the de- 
soe 
Cc. lanuginosa, Mx., as he says the “pistillate spikes are 
closely sessile,” while those of C. trichocarpa are pedun- 
cled ; and the “fruit most dense and short.” while that of 
latter is not very close-set and is ovate-lanceolate, or 
ovate-conic, beaked, and two toothed. : ;
