    Calyx glabrous; tube 5–8 mm. long; limb-tube 6–10 mm. long, usually with 5 distinct ribs (decurrent lobe bases), never splitting; lobes filiform or occasionally narrowly linear, 4–15 mm. long, somewhat widened at base but clearly separated by sinuses.
    Corolla
    Corolla white or cream with red to purple spots at the throat, glabrous outside; tube narrowly cylindrical at base then campanulate above, (3–)4.5–7 cm. long, 2.3–4.5 cm. wide at top, the cylindrical portion up to 1/4 the total length; lobes overlapping to right in bud, ovate 2–3 cm. long, 1–2.2 cm. wide, rounded to acute or subacuminate.
