Plants polycarpic, height in flower 90–170 mm. Caudex unbranched or branched, 110–200 mm long. Flowering stems terminal only or terminal and lateral, 3–12 per plant, 1.1–3.1 mm diam. when dry, lateral flowering stems decumbent, flowering stem leaves 3–4 pairs per stem (not applicable in cases where no rosette is present on multi-branched plants), lowest pedicels from halfway up flowering stem to near apex of flowering stem. Rosette of leaves absent, not very distinct, or distinct from flowering plants leaves; leaves narrowly elliptic, 36.6–53.1 mm long, 8.4–12.6 mm wide, flat, not recurved, margins thickened, apex rounded and retuse; petiole distinct, 11–13 mm long, 4.7–6.3 mm wide at leaf base. Flowering stem leaves the same but smaller. Pedicels 1 or 2 per leaf axil, 6.2–17.8 mm long, 1.2–1.3 mm diam., 0.7– 1.0 mm diam. when dry. Flowers 15 to more than 100 per plant, 9.9–14.1 mm long. Calyx 9.3– 12.2 mm long, hairs at calyx–corolla fusion line present; lobes 7.5–10.3 mm long, 2.4–3.4 mm wide at base, plane, apices obtuse (widest near the apex), margins smooth, sinus hairs absent. Corolla 8.4– 11.8 mm long, white or tinted red to purple, veins colourless or purple; tube 2.1–4.4 mm long; lobes 6.3–8.8 mm long, 3.8–5.0 mm wide, hairs below sinus absent or present; nectary 1.2–1.5 mm from corolla base.
