Mexico: The City of Durango and vicinity, April to Nov. 1896, E. Palmer, #90 



A remarkably showy species of this genus, apparently over- 

 looked by the recent workers who have accepted it as A. longi- 

 flora Ton*., from which species it differs by its more numerous- 

 flowered inflorescence, its much shorter corolla-tube, and there- 

 fore proportionately longer lobes, its more narrow and propor- 

 tionately longer calyx-lobes, and even by its geographic range, 

 not crossing to the east of the continental divide. Intermediate 

 between the two sections of the subgenus Sphinctosiphon with 

 the short tube of one section and the large corolla-lobes of the 

 other. 



The occurrence at Durango, Mexico of this plant causes a 

 great gap in the range, which it is to be hoped may be filled in 

 by future collectors.
