• FLOWERS: Few in branched sprays to 6 cm, each large flower with 5 cream‑white hairy petals over 2 cm long, the 10 hairy stamens joined in a ring around the central style.
• FRUIT: A rounded capsule to 3 cm across, pink to dull yellow‑brown and hairy, without a neck to the fruit stalk, splitting into sections when dry to set free large black seeds which are almost covered by a soft red aril.
