suffruticose, pro-cumbent; branches sparsely stellato-pilose; leaves on longish petioles, ovate-oblong, rugose and sub-plicate, unequally eroso-denticulate, glabrescent on the upper, stellato-canescent on the lower surface; stipules cordate-ovate, amplexicaul, cuspidate, much shorter than the petiole; bracts ovate; calyx campanulate, 5-angled, thickly stellulate, 5-toothed, the teeth short, deltoid, with wide interspaces; petals twice as long as the calyx, the claw longer than the limb; filaments obovate, somewhat longer than the cuspidate anthers; capsule prismatic, 5- angled and 5 -crested, 3–4 times as long as the calyx. A trailing or decumbent, slightly branched, half-herbaceous plant; the branches leafy below, naked above, and ending in a compound pseudo-raceme. Fl. yellow.
