The inflorescence consists of 25-50 cream-white flowers borne in leaf axils on a stalk 9–25 mm (0.35–0.98 in) long that is covered with reddish-brown, short, matted hairs over whitish flattened hairs. The pedicel 3.5–8 mm (0.14–0.31 in) long, thickly covered with flattened hairs that extend onto the cream-white perianth when in bud, the pistil 17–26 mm (0.67–1.02 in) long. The fruit is narrowly egg-shaped, 30–40 mm (1.2–1.6 in) long, 11–17 mm (0.43–0.67 in) wide and a long obscure beak. Flowering occurs in spring.[2][3]
