Minuartia drummondii
Minuartia uniflora
Minuartia drummondii is easily recognized by the proportionally large corollas (petals to three times as long as sepals) and pedicels reflexing in fruit.

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).
