Pedicularis is a genus of perennial green root parasite plants currently placed in the family Orobanchaceae.
Pedicularis groenlandica is a showy flowering plant in the family Orobanchaceae which is known by the common names elephant's head and elephanthead lousewort. This erect plant can grow to a height of 80 centimetres (31 in). Its sharply-toothed fernlike leaves are located low on the stout stem. The stem is topped with a large inflorescence of bright pink to purple or white flowers. Each flower has a long, pointed beak which curves upward, superficially resembling the trunk of an elephant, and the lateral lobes of the flower resemble an elephant's ears. Like other louseworts and related broomrape genera, this is a root parasite which obtains nutrients from the roots of other plants by piercing them with haustoria. This plant is found in the high mountain ranges of western North America, particularly the Cascades and High Sierra, much of Canada and Greenland. It grows in wet environments such as riverbanks.
Orthocarpus luteus is a species of flowering plant in the broomrape family known by the common name yellow owl's-clover. It is native to much of western and central North America, where it grows in many types of plateau, grassland, and mountain habitat.
Orthocarpus pachystachyus is a rare species of flowering plant in the broomrape family known by the common names Shasta owl's-clover and Shasta orthocarpus. It is endemic to central Siskiyou County, California, where it is so rarely seen it was thought to be extinct until 1996, when eight individuals were located. The plant grows in an isolated wilderness but since it apparently only occurs on one single hillside it is considered very vulnerable to extinction.
Pedicularis attollens is a species of flowering plant in the family Orobanchaceae known by the common name little elephant's head. It is native to Oregon and California, where it grows in moist mountainous areas such as meadows and bogs. It is a perennial herb growing up to 60 centimetres (24 in) in maximum height with one or more stems emerging from a caudex. The leaves are comblike, divided into many linear lobes. The inflorescence is a raceme occupying the top of the stem. The sepals of the flowers and the bracts between them are woolly. The flower is under 1 centimetre long and divided into a curving trunklike upper lip and a three-lobed lower lip. It is pink or purplish in color with darker stripes. The fruit is a capsule up to 1 centimetre long containing seeds with netlike surfaces.
Pedicularis centranthera is a species of flowering plant in the family Orobanchaceae known by the common names dwarf lousewort and Great Basin lousewort. It is native to the western United States from eastern Oregon and California to Colorado and New Mexico, where it grows in sagebrush and other basin and plateau habitat. It is a perennial herb producing several short stems a few centimeters tall from a basal caudex. The leaves are up to 20 centimeters long, lance-shaped and divided into many overlapping toothed, wrinkled, or fringed lobes. The inflorescence is a short raceme bearing many long, protruding, club-shaped flowers. Each flower may exceed 4 centimeters in length and is white or pale purple with dark purple tips on the wide ends of its upper and lower lips. The sepals of the flowers are shorter and hairy. The fruit is a capsule around centimeter long containing seeds with netlike surfaces.
Pedicularis dudleyi is a rare species of flowering plant in the family Orobanchaceae known by the common name Dudley's lousewort. It is endemic to central California, where it is known from about ten scattered occurrences along the coast and in the coastal mountain ranges. It has been found in three locations along the Central California coast. The species was named for 19th-century Stanford University botanist William Dudley.
Pedicularis howellii is an uncommon species of flowering plant in the family Orobanchaceae known by the common name Howell's lousewort. It is endemic to the Siskiyou Mountains of the Klamath Range in southern Oregon and northern California, where it grows on the edges of coniferous forests. This is a perennial herb producing one or more stems up to 45 centimetres (18 in) tall from a long caudex. The leaves are up to 20 centimetres (8 in) long, lance-shaped, and divided into many toothed oval lobes; those higher on the stem may be unlobed. The basal leaves fall away early. The inflorescence is a small raceme of flowers occupying the top of the stem. Each white to light purple flower is up to one centimetre long and is sickle-shaped, with a curved beak-like upper lip and a three-lobed lower lip which may be tucked into the hairy mass of sepals. The plant is pollinated by bumblebees including Bombus mixtus. Between the flowers are hairy to woolly triangular bracts. The fruit is a capsule just under a centimeter long containing seeds with netted surfaces.
Pedicularis racemosa is a species of flowering plant in the family Orobanchaceae known by the common names sickletop lousewort and leafy lousewort. It is native to western North America, where it grows in coniferous forests. This is a perennial herb producing several stems up to 80 centimetres (31 in) tall, greenish to dark red in color. The leaves are up to 10 centimetres (4 in) long, linear in shape and lined with teeth. The inflorescence is a small raceme of flowers occupying the top of the stem. Each white to light purple or yellow flower is up to 1.6 centimetres long and is divided into a curved or coiled beak-like upper lip and a wide three-lobed lower lip. The fruit is a capsule over a centimeter in length containing smooth seeds.
Pedicularis semibarbata, known by the common name pinewoods lousewort, is a species of flowering plant in the family Orobanchaceae.
