La Grassette à longues feuilles (Pinguicula longifolia Ramond ex DC., 1805) est une grassette endémique des montagnes du sud de l'Europe depuis la péninsule Ibérique jusqu'aux Apennins[1].

Sous-espèces

La sous-espèce type est endémique des Pyrénées centrales et ses meilleures populations se trouvent dans le Parc national d'Ordesa et du Mont-Perdu [2].

Une autre sous-espèce, la Grassette des Causses, Pinguicula longifolia subsp. caussensis Casper (considérée récemment comme une espèce à part entière et denommée désormais Pinguicula caussensis (Casper) Roccia, Gluch, Lampard, A.S.Rob., A.Fleischm., S.McPherson, L.Legendre, Partrat & P.Temple (2016)), est endémique des Causses (sud du Massif central) et pousse sur les rochers calcaires suintants et plus particulièrement sur les "balmes" (encorbellement au pied des falaises dans les gorges comme celles du Tarn par exemple).

[en] Pinguicula longifolia

Pinguicula longifolia, commonly known as the long-leaved butterwort, is a perennial carnivorous subalpine plant of the Central Pyrenees, found on both sides of the border. It catches its prey by using its modified leaves that lie on the ground and have “densely covered stalked glands that bear a droplet of sticky mucilage on its top.”[1] The need to capture arthropods is driven by the lack of nutrients present in the soil. P. l. subsp. longifolia obtain their nutrition primarily from flying insects, mainly diptera, which replenished the carnivorous plant with nitrogen. P. l. subsp. longifolia grows in wet shady areas and on vertical or overhanging limestone walls. It has been found at altitudes between 700 – 1900 meters. In the spring, the winter buds open and the first carnivorous leaves present themselves. These leaves are then followed by the flowers in early summer. Throughout summer the leaves can grow up to 14 cm in length and have glands present on both sides of the leaves, which is highly characteristic of P. l. subsp. longifolia. More carnivorous leaves arise throughout summer, and when the conditions become unfavourable, around autumn, a protective winter casing composed of scale like leaves is produced, in the centre of the rosette, called the hibernacula, also known as the plant bud. The leaves halt production and the old leaves wither and decay; P. l. subsp. longifolia is now ready for the winter dormancy. There must be optimal growth during the summer for P. l. subsp. longifolia, otherwise they produce weakened hibernacula which rot very easily.
