Discussion
Lithophragma trifoliatum is known from the western slope of the Cascade Range and Sierra Nevada in California. It is closely related to L. parviflorum and was considered a variety by P. E. Elvander (1993). The shape of the hypanthium, the fragrant flowers, the relatively large pink petals, and the relatively large seeds are distinctive. Lithophragma trifoliatum rarely produces seed; in cultivation, self-pollination was unsuccessful (R. L. Taylor 1965). It may represent a sterile derivative of L. parviflorum that now persists by vegetative reproduction.
