General: Perennial herb from a short taproot or a short, brittle, woody stem-base and often some fibrous roots; stems generally lax, erect or ascending, more or less spreading long-hairy, the hairs, especially the upper ones, usually with some purple cross-walls, 1-25 cm tall.
Leaves: Basal leaves oblanceolate or occasionally spoon-shaped, 1-9 cm long, 1.5-11 mm wide; stem leaves reduced upwards, linear or linear-lanceolate, the lowermost abruptly sharp-pointed, the uppermost tapering to a slender tip.
Flowers: Heads with ray and disk flowers, solitary, the disks 10-20 mm wide; involucres 6-9 mm wide; involucral bracts subequal, more or less densely long woolly-hairy, the hairs with dark purple or blackish cross-walls (rarely without or with only a few purplish crosswalls) narrow, loose, tapering to a slender tip, generally heavily tinted blackish-purple, rarely more greenish; ray flowers 50-150, white to purplish, 3.5-6 mm long, 0.5-1 mm wide; disk flowers 2.4-4.8 mm long.
Fruits: Achenes 2-nerved, more or less hairy; pappus double, the inner of about 20-30 bristles, these exceeding the disk flowers, the outer of a few short and inconspicuous scales.
Notes: Some specimens (in or near populations of normal plants) from northern BC and YT have whitish involucral hairs that lack or have only a few purplish crosswalls (Douglas 1995). These plants are extremely difficult to separate from Erigeron uniflorus ssp. eriocephalus with which they may be hybridizing.
