Characteristics

Dwarf, caespitose shrublet forming rather loose tufts 200-500 mm in diam., 200-250 mm in height. Stems subterranean, spreading horizontally, bearing alternate, acute scales up to 5 mm long. Flowering shoots terminating the subterranean stems, 5-7 mm in diam., the shoots producing a crown of spirally arranged leaves at the point of emergence from the soil. Leaves narrowly oblanceolate to spathulate, 120-250 mm long, 8-30 mm wide, tapering to a distinct carmine-tinted petiolar region; apex obtuse, very rarely subacute; glaucous, surface slightly granulate. Inflorescences ovoid to globose, cyathiform, 35-40 mm in diam. Inflorescence buds conic acute. Involucral receptacle 15-20 mm in diam. slightly convex. Involucral bracts 4-5 seriate, the innermost series oblong-spathulate, 30-35 mm long, up to 10 mm broad, apex rounded, concave, broadly obtuse; outer series ovate to broadly ovate 7-15 mm long, 7-10 mm wide, obtuse; outer surface of bracts minutely sericeous, becoming glabrescent to glabrous, margins minutely fimbriate; yellow-green suffused with dull carmine, more uniformly carmine in some specimens. Perianth 30-35 mm long, fairly straight in bud, outer surface glabrous except for the thickly lanate apices of the perianth limbs. Adaxial perianth sheath 4 mm wide proximally, tapering to almost filiform below the limbs, minutely puberulous along inner margins. Limbs 8-9 mm long, linear, glabrous or very sparsely puberulous for the greater part of their length, apices acuminate, thickly lanate. Anthers 4, linear, 5 mm long, terminating in an ovoid-sagittate apical boss. Style adaxially curved 25-30 mm long, slightly compressed longitudinally, tapering subterminally. Pollen presenter linear-filiform, 5-6 mm long, flattened, longitudinally grooved, apex obtuse. Hypogynous scales ovate to oblong, 1.5 mm long occasionally bifid. Flowering takes place from August until November but is somewhat dependent on moisture availability during winter and spring.
