Chapman's Butterwort - Flatleaf Butterwort - Swamp Butterwort
Pinguicula planifolia - Chapman
Lentibulariaceae (Bladderwort) Family


Plant is an upright, glandular perennial. Preferred habitat is swamps, wet soils or standing water, open roadsides where water is persistent in ditches. Distribution is occasional in the Escambia region. This is a species that is very fond of a wet habitat. The deep maroon color of the leaves easily distinguishes the plant from other species growing in this area of SW Alabama. Some specimens may have lighter colors, however, often due to insufficient sunlight.

The leaves are in basal rosettes, no leaf stalk; egg-shaped or tapering to the tip with sides less than equal; margins are smooth and usually curled inward.

Flowers are solitary at the tip of the flowering stem; bisexual in nature; about 2 inches across and divided into deeply cut notches, each part being the image of the other; calyx is 5-lobed; corolla is funnel-shaped and spurred at the base. Color is blue to whitish blue; 2 stamens. Flowers occur in the spring. The deeply notched petals and the flat, lanceolate or elliptic reddish basal leaves, which form a rosette up to 15 cm across, are characteristic of this rare endemic.

Fruit is a capsule.

The flower colors range from pinkish purple to almost pure white. Each of the five lobes of the corolla is deeply incised almost half the length of the lobe. The flowers pose at the tip of a long stem; solitary, bisexual in nature and symmetrical in form; calyx 5-lobed; corolla 2-lipped; 5-lobed. Yellow palate exserts strongly from the corolla tube is clearly visible when the flower is fully open. The same flower seems to last for several days, but strong sunshine is needed to persuade it to open its lobes fully. The flowers are small but can reach almost an inch across when open.
