Flowers 4.5 - 7.5 cm across, borne in the axils on short, thick, pedicels. Epicalyx of 3-5 broad segments which are fused in bud enclosing the flower. Sepals connate into a shortly 5-lobed calyx. Petals pink to mauve, fading to white. Style with 5 radiating stigmatic lobes. Fruit a brown, 5-valved, loculicidal, capsule which is retained on the tree for some months. The interior of the capsule is filled with white 'fibre-glass' hairs, which are irritant, and responsible for the vernacular names of Itch Tree and Cow Itch Tree.
