Bladderwort Utricularia vulgaris, photographed by Rod Gilbert.

Belongs within: Lamiales.

The Lentibulariaceae is a family of small carnivorous plants growing in damp habitats. Species of Pinguicula (butterworts) have sticky glandular leaves that trap insects, while Utricularia (bladderworts) have specialised bladders on filiform leaves that trap aquatic micro-invertebrates.

Characters (from Black & Robertson 1965): Herbs growing in water or wet places; leaves radical, without stipules. Flowers solitary or racemose at summit of erect scapes; irregular, bisexual; calyx persistent, of two or four sepals; corolla two-lipped, the lower lip usually prolonged at base into spur; two stamens, connivent, inserted at base of upper lip of corolla, enclosed; anthers one-celled; ovary superior, one-celled, with numerous anatropous ovules attached to free central placenta; style very short; stigma broadly two-lipped, lips somewhat unequal; fruit a capsule with many small exalbuminous seeds.
