Dicotyledons with Gamopetalous Flowers — Lentibulariece . 
Distribution. —A small Natural Order, dispersed over the Globe from the Equator to the cool 
Temperate zones and Arctic circle. In Brazil one large aquatic species grows in the water collected 
in the leaf-axils of a Tillandsia. 
Number of British Genera, 2 ; Species, 7. 
Leaves when submerged usually much divided and bearing little bladders, filled with air at the time of flowering, 
either scattered through the leaves or on distinct branches. The “ bladders” may be regarded as specially modified 
leaf-segments. 
Calyx 2-lobed as in Bladderwort ( Utricularia ), or 4-5-lobed as in Butterwort (Pinguicula). 
Ovary with a central placenta, free from its origin, as in Primulacese ; ovules indefinite. 
USES, &c.—The species are of very small economic value, and are rarely seen in cultivation. Butterwort 
(Pinguicula vulgaris) is used by the Laplanders to give consistence to the milk of the Reindeer. Some exotic 
Bladderworts bear handsome purple or yellow flowers, and would form a valuable addition to our warm aquaria.

Diagnosis. — Herbs, or more rarely shrubs, with 4-anglecl extremities and 
opposite leaves. Corolla hypogynous, usually more or less 2-lipped. Sta¬ 
mens epipetalous, fewer than corolla-lobes. Ovary 4-lobed, 4-celled, with 
one ovule in each cell. Style 1, gynobasic.
