About
*Pinguicula longifolia*, or the long-leaved butterwort, is a perennial subalpine carnivore notable for its sticky, glandular leaves and its ability to form a protective winter casing called a hibernacula. It is found across the Central Pyrenees, thriving in wet, shady environments.
Field notes
Morphology
The leaves are highly characteristic, featuring glands on both sides and can grow up to 14 cm in length throughout the summer. In autumn, the plant produces a protective winter casing, or hibernacula, composed of scale-like leaves in the center of the rosette.
Distribution & habitat
Central Pyrenees, found on both sides of the border. It is found at altitudes between 700 and 1900 meters.
Ecology
The plant traps prey using modified leaves that are densely covered with stalked glands bearing sticky mucilage. It obtains nitrogen primarily from flying insects, especially diptera, which replenishes nutrients lacking in the soil.
Conservation
The species is endemic to the Pyrenees, and its propagation space is threatened by habitat destruction. It is also threatened by collectors of rare carnivorous plants.
