Discussion

Of conservation concern.

Variety pulchra is known only from the San Juan River basin (Washington and Kane counties, Utah; Coconino County, Arizona). It is of conservation concern in Utah. Recently, S. L. Welsh (Welsh et al. 2003) transferred var. pulchra from Aster glaucodes (syn. H. glauca) to A. wasatchensis on the grounds of its glandularity and “general conformation,” while acknowledging the glaucous foliage shared with Herrickia glauca. Yet the variety does not share critical features of the involucre with H. wasatchensis, and the glandularity is most likely a shared primitive feature within the group and is therefore not indicative of a particular relationship within the group. Distribution and morphology strongly suggest the relationships reported here. Alternately, var. pulchra may represent a distinct species, as hypothesized by G. L. Nesom (1994b).
