Shrub. Stems hairy. Leaves 25-70 mm long, 15-40 mm wide, tripartitely lobed, simply (once-)lobed; margins crenate; indumentum present, with non-tubercle-based simple hairs; stipules present but early deciduous (only visible on youngest leaves). Perianth clearly of two whorls (calyx and corolla), the corolla obvious and prominent. Pedicel present, 10-15 mm long; indumentum present, with stellate hairs. Epicalyx (extra segments or 'bracteoles' immediately below the calyx) present, 6-7 mm long, the lobes free, glabrous. Calyx green, 18-25 mm long, the lobes fused less than half their length, stellate hairs present. Corolla blue or purple, 45-52 mm long, hairs or scales present, stellate hairs present, tubercle-based simple hairs absent. Stamens many, united and arising from a staminal tube around the style; filaments present, 3-4 mm long; anthers 1.3-1.5 mm long. Ovary hairs and scales absent (ovary quite glabrous); style 1, 24-35 mm long, with five style branches or lobes, mostly glabrous. Fruits dehiscent (capsules and follicles), length-width ratio more or less as long as wide, hairs or scales present, stellate hairs present; apex rounded; prickles absent (except perhaps a terminal awn); terminal awns or spines absent; calyx persistent to mature fruit; carpels 3-5; seeds per loculus ≥5.
