Plants 2–13.5 cm. Leaves: basal 2 or 3, blade ovate or elliptic, 10–40 x 5–20 mm, 2 (or 3) -pinnatifid, margins of adjacent lobes nonoverlapping or extensively overlapping distally, serrate, surfaces glabrous or hirsute; cauline 0–2, blade elliptic, 5–25 x 5–10 mm, 2-pinnatifid, margins of adjacent lobes nonoverlapping or extensively overlapping distally, serrate, surfaces scattered hispid.

Discussion

Inflorescences of Pedicularis capitata display no more than five clustered flowers; the long, vertical corolla tube and curved galea that arches over the appressed, broad lobes of the abaxial lip are distinctive. The tip of the galea can be the same color as the corolla tube and abaxial lip but sometimes is a diffuse pink to purple and not distinctly bicolored as in the galeas of P. flammea or P. oederi, with which it is often confused.
