    1. Reviewed by James Morefield    Sep 18, 2002

    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.

    2. Reviewed by Dean Taylor    Feb 9, 2004

    Action: changed name from "Chaenactis douglasii var. douglasii" to "Chaenactis douglasii 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.
