Characteristics

A decumbent shrub with a stout, exposed, woody rootstock, 4.0-2.0 cm in diam., from which arise several stout, unbranched, trailing stems, 2.0-4.0 m in length. Basal branches stout and woody, 2.0-3.0 cm in diam., usually bare or covered with corky bark. Flowering stems often looped or bowed with the inflorescences arising at right angles to the stem. Leaves oblanceolate to obovate, 2.9-5.5 cm long, 0.6-1.8 cm wide, glabrous to glabrescent, the young leaves with a sparse indumentum of short crisped hairs, soon becoming glabrous; apex rounded to subtruncate with 3-4 teeth; leaves usually secundly arranged, often reflexed and bent backwards. Inflorescences solitary, depressed ovoid, 9.0-2.0 cm in diam.; peduncle 3.0-3.5 cm long, arising at right angles to the stem. Involucral receptacle conic acute, 2.0-2.5 cm long, 1.0-1.3 cm wide. Involucral bracts lanceolate acute, 5.0-7.0 mm long, cartilaginous, softly tomentose. Bracteoles broadly obovate to cordate, 8.0-9.0 mm wide, 11 mm long, cartilaginous, thickly lanate proximally; apex abruptly acuminate, 4.0-5 mm long. Perianth 3.5-4.0 cm long, yellowish orange, becoming deep reddish orange to salmon pink with age. Perianth tube infundibuliform, 1.5 cm long, tapering and glabrous proximally, becoming greatly inflated and puberulous distally, 1.0-1.5 mm in diam. proximally, 3.5-4.0 mm in diam. distally; abaxial surface keeled. Perianth limbs lanceolate acute, 4.0 mm long, 1.5 mm wide beset with a hispid ferruginous indumentum. Style curved adaxially, 4.5-6.2 cm long, tapering towards the apex. Pollen presenter narrowly ovoid to conic acute, 1.0 mm long. Stigmatic groove oblique, adaxially placed. Hypogynous scales linear subulate, orange, 4.0-5.0 mm long. Flowering occurs from late September until December.
