Rosette-lvs 3-7 cm. × 5-9 mm., linear-spathulate to oblanceolate, lamina merging into broad ill-defined petiole, tip subacute to obtuse; hairs alike on both surfaces, uniformly stiff, straight, closely appressed, strongly overlapping to hide epidermis completely. Lateral branches erect, up to 18 cm. long, lfless below cyme, lower internodes < lvs. Stem-lvs 15-25 × 2-5 mm., narrow-oblong, tip subacute; hairs like those of rosette-lvs. Cymes us. once forked, ebracteate, many-fld, compact and 2-3 cm. long in fl., internodes and pedicels short. Calyx c. 8 mm. long, lobes c. 1/2 length, subacute; short appressed hairs forming close even silvery cover from which project long stiff hooked hairs that are most numerous towards the base. Corolla apparently deeply coloured, 8-10 mm. diam., tube 10-15 mm. long, narrow-funnelform, lobes c. 3 × 3 mm., ± oblong; filaments broad, fixed between scales, c. = anthers which are c. 2 mm. long and wholly above scales; style at least 2 × calyx, stigma capitate.
