Characteristics

An erect to spreading shrub, 1.0-2.0 m tall, 2.0-3.0 m in diam., with a lax growth habit. Branches somewhat laterally to horizontally spreading, often drooping onto the ground. Single main stem, stout, branching near base; bark smooth, grey. Flowering stems 3.5 mm in diam. covered with a thin indumentum of fine crisped hairs, interspersed with long erect sericeous trichomes. Leaves glabrous, oblanceolate-cuneate, 1.0-2.0 cm wide, 4.5-7.0 cm long, tapering to a distinct petiolar region; apex truncate with 3-5 teeth. Inflorescence somewhat depressed globose to flattened, 5.0-8.0 cm in diam.; usually single but occasionally with up to 3 inflorescences per flowering stem; pedunculate, peduncle 1.0 cm long. Involucral receptacle conic-depressed, 1.0 cm long, 0.75 cm wide. Involucral bracts cartilaginous, closely adpressed imbricate, ovate acute, 5.0 mm wide by 8.0 mm long, sericeous, cinereous. Bracteoles obtrullate-cuspidate, 5.0 mm wide, 0.0 mm long, very densely lanate proximally, sericeous distally. Perianth tube 7.0 mm long, infundibuliform, narrowed proximally (1.0 mm in diam.), becoming swollen and inflated distally (4.0 mm in diam.), then becoming sharply constricted; glabrous proximally, puberulus distally. Perianth claws 2.0 cm long, beset with long, erect to spreading silky trichomes. Perianth limbs elliptic, 2.0 mm long, densely sericeous with long, straight, white or ferruginous trichomes. Anthers sessile, elliptic. Style 3.5-5.0 cm long, tapering and becoming somewhat incurved in the distal third. Pollen presenter conic ovoid 1.5-2.0 mm long, stigmatic groove terminal. Hypogynous scales 1.0 mm long, linear subulate. Although the peak of the flowering period is between September and November, inflorescences are produced rather erratically from May until as late as March.
