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 298 in the U. S. National Her- 

 barium is to be taken as typical of it. Our plant is much more closely related to A. 

 ivrightii and to A. undenvoodii Rydb. It does not belong in the same group with 

 A. dracunculoides. Metcalfe's 1248 was distributed imder a manuscript name of 

 Doctor Greene's, but so far as we can learn the name has never been published.
