Characteristics

A rounded spreading shrub to 2.0 m in diam., 1.5 m in height, with a single main stem and horizontally spreading stems often drooping onto the ground. Flowering stems suberect or horizontally spreading, 5.0-8.0 mm in diam., beset with a short indumentum of fine crisped hairs, becoming glabrescent. Leaves patent to suberect, ovate, cordate and entire to oblong obtuse and with up to 6 teeth at apex; 2.0-4.5 cm wide, 2.0-8.0 cm long; pubescent at first, soon glabrous; oblong obtuse at lower end of stem becoming ovate cordate and entire below inflorescence. Inflorescences depressed globose, 0.0-2.0 cm in diam., solitary, or in groups of 2 or 3; usually borne at right angles to flowering stem; pedunculate, peduncle to 1.5 cm long. Involucral receptacle narrowly conic acute, 3.0-3.5 cm long, 8.0 mm wide. Involucral bracts ovate acuminate, 4.0-5.0 mm wide, 8.0 mm long, closely adpressed imbricate, cartilaginous, thinly tomentose. Bracteoles obtrullate acuminate, concave, apex incurved; 7.0 mm wide, 8.0-0.0 mm long; cartilaginous, thickly lanate proximally. Perianth 3.0-3.5 cm long, yellow, orange or crimson. Perianth tube 8.0-0.0 mm long, cylindric glabrous. Perianth claws crimson to hyaline. The 3 adaxial claws united into a sigmoidly curved sheath, glabrous, but slightly hispid on margins of the 2 lateral adaxial claws, strong coiled subterminally in an adaxial direction. Abaxial claw sparsely puberulous. Perianth limbs ovate acute, 3.0 mm long, 2.0 mm wide, hispid. Anthers subsessile, ovate, filament 1.0 mm long, swelling into 2 fleshy protuberances at the base. Style 4.5-6.0 cm long, held horizontally but curved adaxially in subterminal region. Pollen presenter obliquely tubinate, apex truncate with an obliquely placed stigmatic groove. Hypogynous scales subulate, 2.0 mm long. Flowering commences in August and continues until January. Although the style and perianth may vary from yellow to crimson, deep orange is the most frequently encountered colour.
