Pinewoods Lousewort (Pedicularis semibarbata)
Description
Pedicularis semibarbata is a perennial herb producing several stems up to 20 centimeters long from a caudex, but most of the stem is beneath the soil and the plant is low on the ground. The leaves are up to 20 centimeters long, lance-shaped shape and divided into many toothed or lobed segments.The inflorescence is a raceme of flowers with hairy bracts and sepals surrounding the flower bases. Each hairy red- or purple-tinged yellow flower is club-shaped and may exceed 2 centimeters in length. Toward the middle it is divided into a broad hooded upper lip and a three-lobed lower lip.Like many species in the broomrape family, the lousewort is a root-parasite. This species taps nutrients from conifers and the lupine Lupinus fulcratus.Some authors recognize the Pedicularis semibarbata subtaxon charlestonensis, which is endemic to Nevada
