Rosette us. single, lvs spathulate or lamina elliptic, 2-6 cm. × 4-12 mm., tip rounded and ± mucronate, petiole c. = lamina-length, narrow but ill-defined; hairs on upper surface spreading, uniform, fine, crowded, on undersurface sparser, shorter, retrorse. Lateral branches ascending or erect, few to many, up to 20-30 cm. long, inter-nodes us. = or > lvs. Upper stem-lvs sessile, spathulate to oblong, mostly 1-1·5 cm. long, tip subacute; hairs on upper surface silky, ± appressed, overlapping, on undersurface sparser, shorter, irregularly arranged. Cymes ebracteate, except sts towards base, mostly simple and terminal, either on primary laterals or on secondary laterals arising from axils of stem-lvs; internodes between frs > calyx; pedicels very short. Calyx c. 4 mm. long, lobes > 1/2 length, narrow, subacute; hairs long and straight towards tips, shorter and hooked towards base, with very short sparse hairs overall. Corolla white or yellow, tube = or > calyx, widest at top, lobes rounded, concave; filaments very short, fixed below scales, anther-tips barely reaching scales; style c. = tube in fl. Nutlets ± pointed, ± keeled.
