Mém. Soc. Imp. Naturalistes Moscou 6: 49, plate 9, fig. 2. 1822.

Common names: Langsdorff's lousewort
Treatment appears in FNA Volume 17. Treatment on page 525. Mentioned on page 512, 513, 526.

Plants 4–30 cm. Leaves: basal 0–10, blade elliptic, 10–30 x 3–15 mm, 2-pinnatifid, margins of adjacent lobes nonoverlapping or slightly overlapping distally, serrate, surfaces glabrous; cauline 1–4, blade elliptic, 10–40 x 2–10 mm, 1-pinnatifid or 2-pinnatifid, margins of adjacent lobes nonoverlapping or slightly overlapping distally, serrate, sometimes crenate, surfaces glabrous, sometimes sparsely tomentose. Racemes simple, 1–6, exceeding basal leaves, each 10–50-flowered; bracts subulate or linear, 5–25 x 1–10 mm, undivided or 1-pinnatifid, proximal margins entire, distal serrate, surfaces glabrous or sparsely tomentose to tomentose. Pedicels 2.5–5 mm. Flowers: calyx 6–11 mm, glabrous or moreorless tomentose, lobes 5, triangular, 2–5 mm, apex entire or serrate to dentate, glabrous; corolla 17–25 mm, tube pink or lavender, 11–13 mm; galea pink or lavender, 6–12 mm, beakless, margins entire medially, 1-toothed distally, apex strongly arching over abaxial lip; abaxial lip pink or lavender, 5–8 mm.

Distribution

Alta., B.C., N.W.T., Nunavut, Yukon, Alaska, Asia

Discussion

Subspecies 2 (2 in the flora).

Pedicularis langsdorffii may be mistaken for P. hirsuta, P. lanata, and P. sudetica, which have similar growth forms and habitat requirements. Pedicularis langsdorffii generally has larger, pink to lavender corollas with toothed galeas that strongly arch over the abaxial lips in contrast to the smaller, toothless, pink corollas and slightly arching galeas of P. lanata. Pedicularis sudetica has up to five cauline leaves or lacks them. The straight, smaller galeas and pale pink or white corollas of P. hirsuta differentiate it from P. langsdorffii.
