Leaves opposite; petiole shorter than to ca. as long as leaf blade; leaf blade ovate to suborbicular or reniform, (1.5--)6(--8) X 1--4(--6) cm, transparent glandular striate, stripes visible with transillumination becoming black and distinct when dry, glabrous to densely strigillose, base truncate to cordate, apex acute, obtuse, or rounded. Pedicel 1--5 cm, usually shorter than subtending leaves, glabrous to densely pilose. Flowers solitary, axillary. Calyx lobes lanceolate, elliptic-lanceolate to linear or subspatulate, (4--)5--7(--10) mm, glabrous, pubescent or with hairs only on margin, apex acute to subobtuse. Corolla yellow; tube 2--4 mm; lobes narrowly ovate to sublanceolate, 5--11 mm, long black glandular striate, apex acute to obtuse.

This species is complex and variable. Variation in the density of hairs, and the size and shape of the leaves and calyx lobes is continuous, and makes it difficult to find correlated characters that serve to divide the species.

Used as a diuretic.
