Growing prostrate to ascending with glandular stems 12 to 45 centimeters long, it spreads in low, sprawling patches. Its leaves are elliptic to lanceolate, 4 to 25 millimeters long, with coarsely wavy-toothed edges and glandular undersides. The tiny fruits are less than 0.5 millimeters in diameter with smooth walls that adhere closely to the seed.
