Common names: Subalpine Fleabane, Peregrine Fleabane, Wandering Daisy

(SYN: E. peregrinus)

UBC still uses Cronquist's classification while ITIS has changed the species naming to E. glacialis var. glacilis. Based on the specimens below I tend to agree with UBC/Cronquist so have changed the naming as shown. Cronquist's naming better establishes the morphological and geographic differences of the species .

Hitchcock lists 2 ssp. (peregrinus & callianthemus) each with 3 vars.
ssp. peregrinus: ray flowers are generally very pale to white. leaves often toothed. (Wet Area habitat) Common west of Cascades to coastal.
var: dawsonii
var: peregrinus: AK
var: thompsonii: sOM
ssp. callianthemus: ray flowers are generally rich rose-purple or darker. Leaves generally entire. (Open Hills habitat) Common throughout east and west Cascades.
var: scaposus: small, alpine
var: angustifolius: Uncommon. subalpine
var: eucallianthemus: Common. subalpine

USDA lists five varieties and two subspecies:

ITIS and eFlora.org list two varieties:
var. glacialis: (SYN: ssp. callianthemus with 3 varieties) Found wNA. Peduncles densely strigillose (stiff, slender bristles) with loosely appressed, slightly crinkled hairs; leaf faces glabrous or villous
var. hirsutus: (SYN: var. hirsutus) Found in CA & NV. Peduncles hirsute (long, rather stiff hairs) to hirsuto-villous; leaf faces hir-sute to hirsuto-villous, (Peduncles are hairier than var. glacialis).

UW Herbarium states that all WA flowers are (E. glacialis var. glacialis)


Note lance shaped, alternating sessile (slightly hairy) stem leaves with no teeth (entire). Stem has short soft hairs. Not as many as Eucaphalus paucicapitatus.

The Olympic and west North Cascade flowers are whiter, few basal leaves, with dense short hairs on leaf edges, and grow in multiple habitats. Mt. Rainier flowers start rose-purple and age toward white, have numerous basal leaves with few short hairs. Lower stem is red-purplish and grows in dry open areas.
