Pedicularis Semibarbata, Pinewoods Lousewort

Pedicularis semibarbata occurs all across the Sierra Nevada, and in some other mountainous areas in California, plus a few places in Nevada including the Charleston Mountains near Las Vegas, and also a small part of south Oregon. Plants are low-growing, just a few inches, though a half of more of the stem is buried below ground. Stems (and calyces) are reddish, with a sparse covering of tomentose hairs. Leaves are divided into between five and 12 pairs of angular, toothed lobes. Leaves generally rise higher than the inflorescence.

Flowers have a hairy, reddish-yellow corolla, up to 1 inch long, with a hooded (not beaked) upper lip and a partially recurved lower lip, divided into three small, rounded, equally-sized lobes. The four anthers are slightly exserted, and attached by hairy filaments.
