Calyx: lobes broadly triangular, 1.5-2 mm long, with rounded often obtuse apices, with recurved hairs and marginal cilia, fleshy, grey-green. Corolla tubular, fused basally for c. 0.8 mm, white or cream; lobes oblong to oblong-oblanceolate, 3-4 mm long, obtuse and with indistinct dorsal appendage, scarcely recurved.
