Characteristics

Much-branched shrubs, (0.3-)1.0-1.5(-2.5) m high, younger branchlets leafy, older ones leafless, often arcuate, indurate. Stems often arising from a woody, underground rootstock, greyish brown; indumentum of young stems closely whitish tomentose, forming lengthwise patterns with cork on older branches, which gradually become glabrous; cork fissured lengthwise, with sclerenchyma fibres protruding between fissures; leaf scars oblate, leaves greyish green, drying greyish brown, ascending, diverging at an angle of ±40°, imbricate, overlapping up to 50%, laterally compressed, plane shape linear to narrowly lanceolate, length x depth (2.0-)3.2-4.4(-10.0) x 0.5-0.8 mm, adaxial surface concave, tomentose, abaxial surface glabrous: lamina longitudinaly folded, midrib distinct and somewhat keeled, with 2 or more lateral veins visible as faint striae when fresh, base sessile; apex tapered or acute; margins glabrous, involute. Inflorescences with multiflowered main and co-florescences; spikes usually extended, 10-16-flowered. arrangement subterminal, axis white-tomentose, proliferating growth common. Bracts greyish green, ascending, rhombic to obtrullate. distinctly angled, length x depth (4.4-)5.1 x 1.4(-1.7) mm; lamina folded lengthwise and keeled, adaxially concave (inside), abaxially slightly convex (outside), shortly villous inside, glabrous outside, coriaceous; wings coriaceous, distinctly 4-or 5-ribbed; base cuneate; midrib shortly extended into an acute apex; margins glabrous, involute. Floral envelope ±6.2 mm long, papyraceous and yellow-pink during pollination, dehydrated after shedding of pollen, turning red to brown. Hypanthium glabrous at ovary, neck scantily tomentose, ±1.6 mm long. Sepals: outer sepals cymbiform. inner sepals obovate, outer and inner sepals adaxially scantily tomentose. abaxially glabrous. Androecium with filaments of antipetalous whorl ±0.7 mm and those of antisepalous whorl ±1.4 mm long; anthers ovoid, ±0.9 x 0.4 mm. sub-basifixed. 2-thecous and 4-locular. Ovary ±2.1 x 1.1 mm. Fruit an achene with pericarp membranous and dry, ±2.6 x 1.5 mm. enveloped by persistent. loosely arranged hypanthium. breaking up at neck base due to dehydration and unification of tissue, resulting in the sepals and androecium being shed.
