Discussion

The present circumscription of Potentilla drummondii differs from that of B. Ertter (1992, 1993), which encompassed P. breweri and P. bruceae as varieties (see 28. P. bruceae discussion for details). The description above focuses on large, eglandular, subpinnate plants that occur in mountains from the central Sierra Nevada and northern Coast Ranges of California to the Olympic Peninsula of Washington, east to southern Alberta. At least some collections previously identified as P. glaucophylla (as P. diversifolia Lehmann) from the Kenai Peninsula in Alaska can be readily accommodated within this concept, as can collections from the Cabinet Mountains in Montana. The distinction between P. drummondii and subpalmate P. glaucophylla can be vague; in general, the proximalmost leaflets of P. glaucophylla are relatively small and often entire; in P. drummondii proximalmost leaflets are similar in size and dissection to other leaflets.

Pinnate-leaved regional variants merit further attention; in particular the smaller form described as Potentilla cascadensis, and glandular plants in the northern Coast Ranges of California. Relatively small plants forming uniform populations in the southern Sierra Nevada may represent stabilized hybrids with P. breweri.

The inclusion of Potentilla bruceae and P. drummondii in sect. Graciles differs from that of J. Clausen et al. (1940) and B. C. Johnston (1980, 1985), who allied both species with P. breweri in sect. Multijugae. Although subpalmate to subpinnate leaves are anomalous in primarily palmate sect. Graciles, doubled proximal leaflets and an indistinct transition between the rachis and axis of the pinnatisect terminal leaflet in these two species suggest that this state is derived from a palmate progenitor. Habit and petioles also are more compatible with sect. Graciles than sect. Multijugae.
