Characteristics

A prostrate shrub forming large, flat, dense mats, 1.0-6.0 m in diam., 0.0-5.0 cm in height. Basal branches stout and woody 5.0 cm in diam., arising from a large woody rootstock 5.0-0.0 cm in diam., and then spreading horizontally along the ground. Flowering stems arising at perimeter of mat; slender, terete, 1.0-2.0 mm in diam., trailing along the ground, often bearing short lateral flowering branchlets. Leaves oblanceolate to linear-spathulate, 0.0-0.0 mm long, 3.0-6.0 cm wide; apex usually truncate and trifid, occasionally entire and acute; glabrescent to glabrous, usually sparsely covered with short crisped hairs at first, soon becoming glabrous; sessile, arising from stems in a subsecund to secund manner, slightly twisted at base. Inflorescence globose, 2.0-3.0 cm in diam.; pedunculate, peduncle 1.0-2.0 cm long. Involucral receptacle depressed-ovoid, 2.0-3.0 mm in diam. Involucral bracts ovate acute, 3.0-4.0 mm long, 1.0-2.0 mm wide, imbricate, cartilaginous, shortly tomentose, the apices somewhat recurved and minutely crinite. Bracteoles broadly ovate acute 3.0 mm long, 2.0 mm wide, lanate. Perianth 5.0 mm long. Perianth tube 4.0 mm long, glabrous but slightly villous distally; narrowing proximally. Perianth claws pale yellow-green, villous; becoming equally recurved in the subterminal region. Perianth limbs narrowly lanceolate acute, 1.0 mm long, tomentose, dark brown when fresh. Anthers sessile, narrowly lanceolate, 0.75 mm long, apical boss pointed, yellow. Style 8.0-1.0 mm long, straight, tapering in the upper third; pale yellow becoming dull carmine with age. Pollen presenter conic-ovoid, yellow; stigmatic groove terminal. Hypogynous scales linear, filiform, hyaline, 2.0 mm long. Flowering takes place between June and November. The bright yellow inflorescences are very sweetly scented. Flowering takes place from August to January with a peak during September and October. The inflorescences are pale yellow to green, fading to carmine and are produced in great profusion at the height of the flowering season.
