Botanic information
Leaf: The sessile dark green leaves are bipinnate up to 90mm (3½) wide with pungent linear lobes that are up to 25mm (1in) long. The base of the leaf is winged and the recurved margins commonly enclose the slightly pubescent underside.

Flower: The creamy white salverform flower has a pedicle up to 10mm (⅜in) long with spreading reflexed perianth segments up to 4mm (⅛in) long. The exserted pistil is up to 4mm (⅛in) long and the flowers are arranged in an erect sessile raceme. They appear during spring and are pollinated by insects.

Fruit: The oblong follicle is up to 6mm (¼in) wide with a heavily wrinkled pericarp (hence, corrugata). It contains an obovoid seed up to 6mm (¼in) long with a slightly recurved margin. This plant egenerates from seed after low intensity fire.
