Inflorescences apparently arising singly in 2-3 upper axils, pubescent, up to 8 cm long. Bracts narrowly oblong, up to 1 cm. Pedicels about 1.5 cm. Calyx-tube slender, elongate, up to 3 cm, terete or obscurely angled, ± pubescent. Sepals elliptic, the two larger 2-2½ by 1.5 cm, the remainder about half as large, rounded, white.
