Flowers: on long pedicels; corolla variegated blue and white, the throat longer than the limb, which is two-lipped, the upper lip two-cleft, its lobes recurved, the lower lip larger and three-lobed.

A pretty, fragile, little plant, with numerous variegated blue and white blossoms. It grows thickly in moist places, seldom attaining more than eight inches in height. It is not unlike a very tiny Lobelia.
