Hypanthium 0.8–1.4 cm long, 0.9–1.4 cm in diameter. Calyx synsepalous; tube adnate to the ovary, forming a hypanthium, hemispheric, obconic, obovoid, turbinate, or rarely oblong, smooth or with 10 longitudinal furrows, rarely muricate or with 10 longitudinal ridges; lobes 5, valvate, either less than 1⁄2 as long as the corolla, distinct or rarely connate at base, persistent, triangular or deltate, rarely oblong or ovate, firm, green, or as long as the corolla (rarely only ⅔ as long), connate for 1/5–⅘ their length, deciduous, mimicking the corolla in shape, texture, and color.
