Basal rosette leaves usually conspicuous, with ± winged petiole, the latter 30–80 mm long; blade elliptic-lanceolate or ± spatulate, fleshy or thick, 15–35 mm long, 10–18 mm wide, obtuse; cauline leaves narrowed at the base into pseudo-petiole, blade obovate, lanceolate or spatulate, 11–15 mm long, 7–9 mm wide, obtuse.. Inflorescences corymb-like, 1–few-flowered; pedicels 13–34 mm long, pedicel of the terminal flower always shorter than pedicels of lateral flowers; bracteoles obovate-(lanceolate) or subspatulate, 8–10 mm long, 3–5 mm diameter, obtuse.. Flowers (4–)5(–7)-merous.. Calyx lobes: 2 wider than others, oblong to subspatulate, 5–11 mm long, 2–4 mm wide, obtuse or truncate.. Corolla pale blue or white with brown-purplish median dorsal stripes; tube very short, 1–3 mm long; lobes obovate, 9–27 mm long, 6–11 mm wide, subacute or acute to truncate or emarginate; nectaries 2 per lobe, yellow with green patches around, oblong or elliptic in outline, pocket-like or flat, 0.7–2.6 mm long, 1–1.6 mm apart, 1.4–4 mm from base of lobe, margin fimbriate, fimbriae 1.9–2.5 mm long, some basally connate.. Stamens with filaments 3.8–7.7 mm long, 0.7–0.9 mm wide, ± dorsiventrally flattened, scale-like projections present at their attachment point to the base of the corolla lobes; anthers oblong or elliptic, 0.7–3 mm long.. Ovary oblong, 4–7 mm long, 2–4 mm diameter; style obsolete; stigma bilobed, lobes 0.6–1.4 mm long, 1–3.2 mm wide, obtuse; parietal placentae indistinct..
