Flowers	sepals elliptic, oblong, or ovate, 5–6 × 2–3 mm, chartaceous or coriaceous, abaxial surface muricate or smooth; corolla lavender to red-purple, funnelform, 30–40 mm, limb 20–25 mm diam.	diurnal; sepals oblong, orbiculate, or ovate, 6–7 mm, coriaceous, margins sometimes scarious, apex obtuse, sometimes mucronulate; corolla red, salverform, (25–)40–50 mm, limb 25–30 mm diam., weakly 5-lobed or notably 5-lobed in age.
