 by the not very copious fringed appendage.

 and Tery strict axillary flowering branchlets in all but the low- 

 est axils, often 18 inches high; stem distinctly obtusely angled :

Type specimens collected by myself at Santa Eita del Cobre, 

 southern New Mexico, 11 Oct. 1880. The plant resembles, at 

 first glance, the pale-flowered A. strictiflora of middle Colorado, 

 but it is very distinct.

 To the description of these I add diagnoses of a number of 

 western species of the genus, all but one of which were collected

 specimens have already been distributed to many herbaria under 

 the names here used.
