Flowers are white, minutely tomentose outside, glabrous at throat; tube shorter than sepals, 6–7 mm (0.2–0.3 in); lobes oblong, as long as tube. Disc longer than ovary. Ovary pubescent at apex. Follicles 2, cylindric, to 30 cm (12 in) by 0.8–1.2 cm (0.3–0.5 in), yellow hirsute. Seeds oblong, 1–2 cm (0.4–0.8 in) by about 5 mm (0.2 in), coma 2–4.5 cm (0.8–1.8 in).
