DESCRIPTION: A large spreading shrub to c. 3m x 5m with a mid-dense habit and infertile inflorescences.
Branchlets bronze with dense matted hairs, becoming grey with a shiny waxy layer with age, striate, erect to slightly spreading.
Leaves normally pinnately divided, occasionally simple, to 25cm long and to 18cm wide. Leaf lobes to 17cm long and to 8mm wide. Upper surface dark green with scattered deciduous appressed white hairs mostly shed with age. Lower surface with a mixture of white and bronze appressed hairs either side of a bronze-haired midvein.

Perianth 12mm long (average) x 8mm wide, yellow-green at the base, becoming orange then pinky-red to deep burnt red at the top of the curve, lightly covered on the outer surface with a mixture of bronze and white appressed hairs which become dense and bronze on the limb.
