Pedicularis lapponica, the Lapland lousewort, is a perennial hemiparasitic species of flowering plant in the family Orobanchaceae with yellow to creme coloured flowers.[1]
Description
[edit]The plant has an unbranched (or very rarely branched) stem of 10–25 cm tall which grows from a creeping rootstock with long slender rhizomes.[2] No rosette is present. Stem leaves are narrow, elongated, and compound with toothed sections, the lower on long petioles. The inflorescence is capitate. The corolla is up to 2 centimeters long and is usually milk white.[3] It is surrounded by toothed sepals. The fruit is a flat, beaked capsule 8–13 millimetres (0.31–0.51 in) long.
Compared to P. lanata, P. lapponica has a breeding system with a lower capacity for outcrossing in West Greenland (Disko) and less morphological variation.
It is perennial (in some cases biennial).
Distribution
[edit]Pedicularis lapponica is widely distributed on the northern hemisphere in the arctic and boreal zone.[4]
In Greenland it is found in West Greenland between 62°N and 72°30’N and in East Greenland between 69°N and Bessel Fjord, 75°58'N.[5]
Habitat and ecology
[edit]Pedicularis lapponica is hemiparasitic on a number of host species.[6] It is found in arctic to alpine tundras, heathlands, moist hummocky tundras, and dwarf shrub heath.
