Wahlenbergia tenerrima (H.Buek) Lammers

A diffuse or sprawling much branched shrublet, rarely erect. Stems slender, up to 50 cm long, brown, shortly hairy. Leaves alternate, fasciculate, reflexed, lanceolate to ovate-lanceolate, 3-5 mm long, 1-1.5 mm wide, acute or acuminate, rather thick, concave above, usually entire. Leaves most commonly distant and shorter than the internodes. Flowering branches long, slender, often branched, the flowers not crowded, in a raceme-like inflorescence. Flowers solitary or paired: bracts very small: pedicels hairy, ranging from very short to 2.5 mm long. Calyx lobes 1.5-2 mm long, triangular-acute, slightly keeled, the edges slightly revolute. Corolla blue or blue-purple, rarely white, 5-8 mm long, the tube very short, the lobes narrow, glabrous. Bases of the filaments broadly rhombic, ciliate especially on the obtuse angles. Style deep blue, gradually thickened to the top. Ovary half-inferior, shortly hairy, the lower part rounded, 1 mm deep, 2 mm diameter. Fruit 3-4 mm diameter, 1.5-2 mm long, distinctly ridged: valves 2-3 mm long, longer than the spreading calyx lobes.
