Old specimen from U.S.D.A. herbarium, without collection data [except "Hakodadi"] but probably from Perry Expedition and annotated by A. Gray (?) as "Trillium erectum var. album". Protologue cites "Trillium erectum var. album, Gray in Perry, Exped. 2. p. 320. Hakodadi" [NOT = Trillium erectum var. album (Michx.) Pursh.].
