Inflorescences paniculate, with ascending branches, 20–50 cm, grayish-hairy; bracts ovate to lanceolate, shorter than flowers. Tepals creamy white to yellow, broadly ovate, not clawed, 6–15 mm, margins strongly erose-ciliate or inner shallowly fimbriate; gland 1, basal, green, V-shaped, elliptic; ovary densely tomentose; pedicel 6–15 mm.
