Characteristics

An erect, rigid, tree-like shrub to 3.0 m in diam., with a stout woody trunk to 0.0 cm in diam. Bark on basal branches and trunk smooth, grey. Young plants rather sparsely branched with stiffly erect stem, older plants becoming more divaricate. Flowering stems stout, woody, 8.0-0.0 mm in diam., with a thick villous to arachnoid cinereous indumentum of short crisped hairs. Leaves glabrous and coriaceous, subimbricate, oblong to broadly oblanceolate-cuneate, 5.5-0.0 cm long, 2.0-3.5 cm wide. Leaf apex rounded, bearing 7 to 10 very prominent, rounded teeth, frequently deeply incised. Inflorescences sessile to subsessile, ovoid, 8.0 cm long, 6.0 cm wide, usually borne singly but occasionally with up to 4 inflorescences per flowering shoot. Involucral receptacle narrowly conical, acute, 3.5-4.0 cm long, 1.0 cm broad. Involucral bracts ovate, carinate on adaxial surface; the apex caudate, very long acuminate, recurved, up to 2.0 cm long, margins fringed with long cilia, the adaxial surface shiny and carmine in live state. Bracteoles cartilaginous, obtrullate, carinate on adaxial surface, 1.0 cm long, 0.6 cm broad, apex long acuminate, somewhat incurved, margins ciliate. Perianth tube 0.0 mm long, cylindric, somewhat laterally compressed, glabrous but slightly puberulous distally on the abaxial surface. Perianth claws yellow when fresh, becoming bright carmine with age, particularly on the inner surface; hirsute, with long straight trichomes interspersed between a dense, shortly villous indumentum. Median adaxial claw glabrous proximally. Perianth limbs broadly lanceolate, acute, 5.0 mm long, 2.0 mm wide, covered with a dense indumentum of short crisped hairs, the three abaxial limbs beset with long silky trichomes. Style 5.5-6.0 cm long, 1.5 mm in diam., straight to slightly arcuate, tapering in the subterminal region. Pollen presenter conic acute, orange, upper half yellow; stigmatic groove terminal, green when fresh. Hypogynous scales subulate, 2.0 mm long, white. Flowering takes place from September to December.
