quite glabrous; stem and branches filiform striate, twining; leaves shortly petiolate, ovato- or oblongo-lanceolate, dentato-lobate at the base, remotely denticulated at the apex; upper ones lanceolate crenato-serrate; racemes axillary, few-flowered, subsessile, about as long as the leafy bracteæ; pedicels much longer than the linear bracteolæ; calyx-lobes linear-lanceolate, erect, spreading, acute, 4–5 times longer than the very short tube, 1/2 shorter than the narrow spreading petals. Habit of Convolvulus like the preceding. Leaves 2–3 inches long, 6–10 lines wide, membranaceous, remotely and bluntish-toothed, the upper ones about 1 inch long, 3–4 lines wide, the bracteæ entire or nearly so. Petiole 2–3 lines long. Raceme shortly peduncled or subsessile, 3–5 flowered, pedicels unequal, 4–8 lines long, with 2 bracteolæ at the base. Calyx-lobes entire, 2 lines long. Petals acuminate, rather longer than the calyx, equalling the style, with incrassate apex. Capsule subglobose, the size of a pea. It varies but rarely with solitary pedicels in the uppermost axils. The raceme, if indistinctly-peduncled, has the aspect of an umbel.
