Inflorescences dense fascicles of numerous flowers, sessile in the centre of a leaf rosette; bracts subtending flowers ovate to ovate-lanceolate, 8–21 mm long, 4–13 mm wide, obtuse, not inflated at the base, much longer than inflorescences.. Flowers violet, blue, rose to whitish.. Calyx almost divided to the base; tube ± 1 mm long; segments spatulate to oblong-spatulate, 2–2.5 mm long, ± 0.5–1 mm wide, obtuse.. Corolla tube 1.5–3 mm long, scabrid-denticulate on both sides; lobes ovate-lanceolate, 1–1.5 mm long, 0.3–0.5 mm wide at base, ± obtuse, scabrid-denticulate on both sides.. Filaments ± 0.6–0.8 mm long; anthers ± 0.3 mm long.. Ovary ellipsoid, ± 0.6 mm long, 0.4–0.5 mm diameter; style ± 1.4 mm long; stigma minute, bilobed.. Capsule ellipsoid, 1.2–2.1 mm long, 1–1.1 mm diameter, bivalved.. Seeds ± 0.3–0.5 mm, surface reticulate.
