Morphology

Pinguicula laxifolia is a perennial rosetted herb bearing pendulous to semi-erect elliptic or oblanceolate 40–68 mm (1.6–2.7 in) long leaves.[1] These are densely covered with stalked mucilaginous and sessile digestive glands, which serve to trap and digest insect prey and absorb the resulting nutrient mixture to supplement their nitrate-low environment. P. laxifolia forms Winter rosettes of succulent, non-carnivorous leaves to conserve energy through the cool, dry seasons, and as a means of self-propagation.

The flowers are pink to pale violet, with a white throat and darker violet markings. They are thought to appear from February through March.[1]

Distribution and habitat

Pinguicula laxifolia is known only from its remote type location in the "El Cielo" cloudforest bioreserve in Tamaulipas, Mexico. Here it grows on well-shaded vertical rock walls from 6300 to 6800 ft. in altitude. Although it appears to have an extremely restricted distribution, little is yet known about this species.[1]
