| Action: changed name from "Chaenactis douglasii var. alpina" to "Chaenactis douglasii var. douglasii
" |
| Reviewer's comments: | | | "This is the dwarfed montane form of var. douglasii sometimes called var. montana. The consistently branched capitulescences place it (perhaps arbitrarily) in var. douglasii rather than var. alpina. " |

| Reviewer's comments: | | | ": "I ammend herein Jim's assingment of this photograph - the plant shown is a polycarpic perennial, and corresponds to the taxon named C. pumila E. Greene; which in my opinion is distinct, very very rare, and poorly known- being insofar as I have seen material narrowly endemic to the Sonora Pass and Sweetwater Mountain region. The complex merits study." Absent this, I would assign this and other polycarpic material to var. alpina sensu lato, although Dorn Madrono 35 161-162. 1988 would restrict var. alpina to the Rocky Mountains; since var. alpina remians on the CNPS list, using the epithet alpina for these high alpine forms, which more probably correspond to the concept of var. montana, is proper.
