This plant has been referred to Artemisia mexicana and to A. discolor, from both of 
which it is amply distinct. Doctor Gray’s remark that it has the appearance of A. 
dracunculoides was certainly unfortunate, if Pringle’s 296 in the U. S. National Her- 
barium is to be taken as typical of it. Our plant is much more closely related to A. 
wrightti and to A, underwoodii Rydb. It does not belong in the same group with 
A. dracunculoides. Metcalfe’s 1248 was distributed under a manuscript name of 
Doctor Greene’s, but so far as we can learn the name has never been published.
