Abstract
The life cycle and the reproductive biology of Pinguicula longifolia s ubsp. longifolia, a carnivorous endemic plant of the Central Pyrenees, has been studied. Plants usually have 3-4 functional leaves (that act as adhesive aereal traps) during their vegetative development, being July the period of maximum capture of prey. Number of prey increases w ith the length of the leaf. Its flowers show an ultraviolet pattern of nectar guides and are pollinated mainly by Hymenoptera and Bombyliida e. Reproductive success is very high, since more than 80 % of flowers produced fruits, and vegetative propagation is very easy. In spite of its restricted distribution, our results suggest that this species is not endangered.
