Rosette-lvs 10-20 × 4-5 mm., lamina obovate, obtuse, petiole short, broad; hairs on upper surface crowded, long, soft, silky, on under-surface fewer and disappearing with age. Lateral branches ∞, decumbent, up to 7 cm. long, occ. branched, internodes us. < lvs. Stem-lvs similar to rosette-lvs near base, becoming sessile above, bracts c. 5 × 2 mm. Cymes us. simple, few-fld, bracteate except at extreme tip, internodes, except the lowest, very short; pedicels c. 1 mm. long. Calyx c. 3 mm. long, lobes > 1/2 length, broad and subacute; hairs mostly very long and soft, a few short and closely appressed. Corolla blue (occ. white), 2-3 mm. diam., tube cylindric, 2 mm. long, lobes 1-1·5 mm. long, ± parallel-sided, narrowing above to obtuse tip; filaments very short, anthers < 1 mm., wholly included, tips not reaching scales; style < calyx, stigma clavate.
