Stem prostrate and rooting, us. < 1 cm. diam., terminating in tuft of ± erect lvs. Lamina submembr., c. 1-3 cm. × 8-20 mm., ovate, regularly shallowly crenate-dentate, base rounded, upper surface uniformly and rather closely covered with short hairs, hairs on undersurface confined to veins; petiole channelled, narrow, us. > lamina, with scattered to crowded hairs. Peduncle hairy, erect, much > lvs, rarely > 20 cm. tall in fr., us. with 2 or 3 ± sessile cauline lvs below floral bracts. Bracts in (1)-2-3 whorls, 2-5-(7) per whorl, subentire and decreasing in size upwards; hairs almost confined to margins. Pedicels up to as many as bracts in each whorl and longer, up to 3 cm. long, clad in flexuous tapering non-glandular hairs. Calyx-clefts all reaching almost to base; lobes c. 5-6 × 1 mm., entire, acute to subacute, hairs few to many, non-glandular. Corolla 15-20 mm. diam., hairs on outside of tube sts sparse or confined to base of posterior lobes.

Stem prostrate and rooting, 1-2 cm. diam., terminating in tuft of ± erect lvs. Lamina subcoriac., 4-10-(15) cm. long, very broadly to very narrowly ovate, regularly and shallowly dentate-crenate, upper surface glab. to hairy, undersurface with hairs, if any, confined to veins; petiole channelled, narrow, > lamina. Peduncle erect, much > lvs, up to 60 cm. tall in fr., us. with a whorl of 2-4 ± sessile cauline lvs below floral bracts. Bracts in 1-8 whorls, us. 4-∞ per whorl, becoming smaller and more nearly entire upwards. Pedicels as many as bracts in each whorl and longer, 3-5 cm. long, clad in short crowded glandular hairs. Calyx-clefts all reaching almost to base; lobes narrow-triangular to narrow-oblong, entire, acute to subacute. Corolla 15-20 mm. diam., with hairs on outside of tube.

Length of lf-lamina us. < 2 × width, us. broadest near ± truncate or rounded, rarely cuneate or cordate, base; upper surface definitely though sparsely hairy all over; petiole us. hairy all over as is peduncle. Calyx-lobes rarely > 7 mm. long.

Length of lf-lamina us. > 2 × width, base cuneate, upper surface us. slightly hairy near petiole; petiole us. hairy all over as is peduncle. Calyx-lobes 6-7 mm. long.

Lf-lamina longer than wide, us. broadest about middle with cuneate to subcordate base, upper surface quite glab.; petiole almost glab. except on the margins. Peduncles and calyx-lobes us. almost glab. calyx rarely > 7 mm. long. Outside of corolla, calyx, pedicels, and margins of lvs and petioles often flushed with red.
