Minuartia uniflora
Minuartia elegans
Minuartia alabamensis was originally described to accommodate much-reduced plants from Alabama (J. F. McCormick et al. 1971). Subsequent studies have shown them to be conspecific with M. uniflora (R. Wyatt 1984).

Minuartia elegans is a part of the M. rossii complex (S. J. Wolf et al. 1979), and is an amphi-Beringian species. The plants are tufted and are known in the flora area only from northwestern Canada and Alaska. Reports from the Pacific Northwest and southern Rocky Mountains likely are referable to M. austromontana.
