Rosette-lvs 5-11 × 0.7-1.1 cm., narrowly elliptic-spathulate, petiole slender and almost = lamina-length, tip subacute; hairs very finely silky, appressed, ± overlapping on upper surface, on undersurface similar but regularly retrorse. Lateral branches ascending to erect, 15-20 cm. long, lfless below cyme, lower internodes < lvs. Stem-lvs c. 25 × 7 mm., lanceolate with rounded base and narrowing to subacute tip, sessile; hairs similar to those on rosette-lvs but less closely appressed, on undersurface many retrorse especially on lower lvs. Cymes us. forked, ebracteate, many-fld, 1-2 cm. long or more, internodes very short, pedicels up to 3-(6) mm. long. Calyx 5-8 mm. long, lobes c. 1/2 length, ± oblong and obtuse, hairs crowded, silky, appressed, ± flexuous but not hooked, many retrorse at base. Corolla "bright pale yellow", c. 9-12 mm. diam., tube c. 6 mm. long, flaring slightly at mouth, scales prominent, lobes spreading, up to 4 mm. long, ± oblong; filaments long and conspicuous, standing well above corolla, anthers c. 1·5 mm. long, versatile; style > stamens, stigma capitate. Nutlets 2.5 mm. long when immature.
