Stem prostrate, rooting at nodes, c. 1 mm. diam., hairy in younger parts, interwoven in extensive mats. Lvs laxly arranged; lamina soft-textured, 3-10 mm. long, orbicular to broadly oval or almost reniform, entire or very obscurely toothed, glab. except sts on lowest part of margins; petiole us. much > lamina, up to 3 cm. long, narrow, sparsely hairy on margins. Infl. apparently cymose, us. of only 2 fls each associated with two lflike bracts. Pedicels short in fl. but elongating to carry fr. well above lvs, hairs few to many, tapering.

Corolla up to 8 mm. diam., glab. outside, tube up to 5 mm. long, oblique, bulging posteriorally near base and inclined to project between the two anterior calyx-lobes.
