Plants 6–20 cm. Leaves: basal 2–20, blade lanceolate to oblanceolate, 10–30 x 2–5 mm, 1-pinnatifid or 2-pinnatifid, margins of adjacent lobes nonoverlapping, serrate, surfaces glabrous; cauline 2–20, blade lanceolate to oblanceolate, 10–40 x 2–5 mm, 1-pinnatifid or 2-pinnatifid, margins of adjacent lobes nonoverlapping, serrate, surfaces glabrous or scattered woolly. Racemes simple, 1–4, exceeding basal leaves, each 12–100-flowered; bracts subulate, 10–40 x 2–5 mm, undivided or 1-pinnatifid, proximal margins entire, distal serrate, proximal surfaces densely woolly, distal glabrous or slightly to densely woolly.

Although Pedicularis lanata has priority, P. kanei (1856) is a synonym that is used commonly for this species. In fact, E. Hultén (1968) in his list of synonyms of P. kanei annotated P. lanata as of American authors. In the same treatment, Hultén listed P. kanei subsp. adamsii, but his distribution map did not show it occurring in North America. H. J. Scoggan (1978–1979) listed P. lanata forma alba Cody based on its white flowers.
The densely woolly inflorescence and bright yellow taproot of Pedicularis lanata are diagnostic. Pedicularis hirsuta, also with a densely woolly inflorescence and similar corolla color, can be confused with P. lanata; however, the galea margins of P. hirsuta are minutely toothed, and the taproots are pale.
