Bearded Lousewort
Pedicularis semibarbata
About Bearded Lousewort (Pedicularis semibarbata) 0 Nurseries Carry This Plant Pedicularis semibarbata is a species of flowering plant in the broomrape family known by the common name pinewoods lousewort. It is native to California and Nevada, where it can often be found in coniferous forests. This 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 flower cluster is a raceme of flowers with hairy leafs 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.
