Pedicularis is a genus of perennial green root parasite plants currently placed in the family Orobanchaceae.
Pedicularis furbishiae, or Furbish's lousewort, is a perennial herb found only on the shores of the upper Saint John River in Maine and New Brunswick. Furbish's lousewort was first recognized as a new species by Maine naturalist and botanical artist Kate Furbish in 1880. It is considered an endangered species in the United States and Canada, and is threatened by habitat destruction, as well as riverside development, forestry, littering and recreational use of the riverbank. It was formerly in the family Scrophulariaceae, but is now placed in the family Orobanchaceae. Once thought to be extinct, it is considered a Lazarus taxon.
Pedicularis groenlandica is a showy flowering plant in the family Orobanchaceae commonly known as elephant's head, little pink elephant, elephantella, or similar common names inspired by the resemblance of the flower to the head of an elephant. It is also less commonly known as butterfly tongue for the long beak on the flower. Like many other plants in genus Pedicularis, it is a parasitic plant and depends on host plants to survive.

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 contorta is a species of flowering plant in the family Orobanchaceae known by the common names coiled lousewort and curved-beak lousewort. It is native to western North America, including southwestern Canada and the northwestern United States, where it grows in moist mountainous habitat, such as bogs, shady forests, and meadows.

The leaves are up to 18 centimetres (7.1 in) long, lance-shaped to oblong, and divided into many linear lobes which may be toothed or smooth-edged. The inflorescence is a raceme of flowers occupying the top of the stem. Each flower is a centimeter long or slightly longer, white to yellowish in color, and divided into a coiled or curved beak-like upper lip and a flat, three-lobed lower lip. The fruit is a capsule up to a centimeter long containing seeds with netted surfaces.
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.
Allium dictuon is a species of wild onion known by the common name Blue Mountain onion. It is native to a small section of the Blue Mountains straddling the border between southeastern Washington and northeastern Oregon in the United States. It grows in Columbia, Garfield and Walla Walla Counties in Washington, plus Umatilla and Wallowa Counties in Oregon.
