Characteristics

Erect, many-stemmed shrubs, ±2 m high, much-branched. Stems grey-brown; indumentum of young stems closely white-tomentose, flaking off on older branches, forming lengthwise patterns with patches of yellowish brown cork; leaf scars prominent. Leaves greyish green (glaucous), imbricate, overlapping ±15%, appressed, plane shape linear to lanceolate, longitudinaly folded and somewhat keeled, length x depth (3.5-) 4.2-5.5(-6.5) x 0.8-2 mm, adaxial surface concave, tomentose, abaxial surface slightly convex, rugose, glabrous; base sessile, abruptly narrowed; apex subacute, sometimes incurved; margins setose. Inflorescences with multiflowered main and co-florescences; spikes usually extended, 8-12-flowered, arrangement subterminal, axis white-tomentose, proliferating growth common. Bracts greyish green (glaucous), appressed, lanceolate, length x depth 4.75-6.0(-7.0) x 1.5 mm; lamina folded lengthwise and keeled, adaxially concave (inside), abaxially slightly convex (outside), villous inside, glabrous outside, coriaceous, obscurely ribbed and reticulately veined; base cuneate; apex obtuse to acute; margins sometimes narrowly membranous. Floral envelope ±5.9 mm long; papyraceous and yellow-pink during pollination, dehydrated after shedding of pollen, turning red to brown. Hypanthium scantily tomentose at ovary, neck tomentose, ±1.7 mm long. Sepals: outer and inner sepals concave lanceolate, outer sepals adaxially glabrous, abaxially tomentose; inner sepals adaxially and abaxially tomentose. Androecium with filaments of antipetalous whorl ±1.2 mm and those of antisepalous whorl ±2 mm long; anthers oblong, 0.9(-1.25) x 0.3 mm, sub-basifixed, 2-thecous and 4-locular. Ovary ±2.4 x 0.9 mm. Fruit an achene with pericarp membranous and dry, ±2.5 x 1.2 mm, enveloped by persistent, loosely arranged hypanthium, breaking up at neck base due to dehydration and torsification of tissue, resulting in the sepals and androecium being shed.
