C. muirii.  Note the mat-like growth form similar to that of Dubautia scabra of Hawai'i.  The rayless heads are also similar in the two species, except those of D. scabra have white flowers and the peripheral receptacular bracts are more or less completely coalesced into a cup-like false involcre.  In Carlquistia the peripheral bracts are only weakly coalesced toward the base.
