Characteristics

Rosette-lvs ∞ and tightly bunched, c. 2-3×0·5-1 cm., petiole narrow, c. = lamina-length and sheathing at base, lamina broad-ovate to obovate, tip apiculate often down-turned; hairs long, crowded, spreading, on undersurface similar but more appressed, the whole plant hoary. Lateral branches ascending to erect, c. 7 cm. long, lfless below cyme, lower internodes < lvs. Stem-lvs up to 15×5 mm., elliptic, sub-acute to acute, sessile; hairs softer and more appressed than those on rosette-lvs. Cymes mostly simple, ebracteate, up to 12-fld, up to 2 cm. long; internodes < calyx; pedicels up to 2 mm. long. Calyx c. 5 mm. long, lobes > 1/2 length, subacute; hairs long and strong, an under-layer shorter and finer, ± appressed, flexuous but not hooked. Corolla white, 7-8-13 mm. diam., tube 3-5 mm. long, with vertically elongated scales at mouth, flaring above into rather wide funnel-shape with lobes c. 3 × 3 mm.; filaments fixed between scales and reaching to level of lobes, anthers c. 1·5 mm. long, versatile; styles c. 2 × calyx in fr., stigma capitate. Nutlets c. 2·2 × 1·3 mm., slightly convex outside, bluntly keeled within, slightly winged round narrow tip.
More
