Richardsonianus Schult.), with straw-colored, scarious-margined perianth leaves, rounded in apex, and with slightly exserted, acute capsules. West of Kodiak Island and elsewhere, a type closer to subsp. alpinus [var. alpestris Hartm.; var. mucroniflorus (Clairv.) Aschers. & Graebn.] occurs, with sessile, dark flowers in compact heads.
