Linnaeus

Sp. Pl. 2: 609. 1753.

Common names: Hairy lousewort pédiculaire hirsute
Treatment appears in FNA Volume 17. Treatment on page 523. Mentioned on page 513, 524, 525, 526.

Plants 3–15 cm. Leaves: basal 3–10, blade elliptic to lanceolate, 5–20 x 2–5 mm, 1 (or 2) -pinnatifid, margins of adjacent lobes nonoverlapping or slightly overlapping distally, serrate, surfaces glabrous; cauline 3–10, blade lanceolate to oblanceolate, 5–30 x 1–7 mm, 1-pinnatifid, margins of adjacent lobes nonoverlapping or slightly overlapping distally, serrate, surfaces glabrous. Racemes simple, 1–10, exceeding basal leaves, each 5–25-flowered; bracts lanceolate, 5–15 x 1–5 mm, 1-pinnatifid 1/2–3/4 to midrib, proximal margins entire, distal serrate, surfaces densely wooly. Pedicels 2–5 mm. Flowers: calyx 7–10 mm, densely woolly, lobes 5, triangular, 1–4 mm, apex entire or serrate, glabrous or ciliate; corolla 11–19 mm, tube pale-pink, sometimes white, 6–14 mm; galea pale-pink, sometimes white, 4–7 mm, beakless, margins entire medially, 1-toothed distally, apex nearly straight to arching slightly over abaxial lip; abaxial lip pale-pink, sometimes white, 4–5 mm. 2n = 16.


Phenology: Flowering Jul–Aug.
Habitat: Tundra bogs, stream and lake banks.
Elevation: 0–500 m.

Distribution

Greenland, Nfld. and Labr. (Labr.), N.W.T., Nunavut, Que., Alaska, Eurasia

Discussion

Pedicularis hirsuta can be difficult to distinguish from P. lanata. Unlike P. lanata, the galea subapex of P. hirsuta is toothed. Floral surfaces of P. lanata are sparsely to densely hirsute; those of P. hirsuta are glabrous. On fresh specimens, the roots of P. hirsuta are pale yellow; those of P. lanata are bright yellow.
