Much-branched, bushy perennial, somewhat woody at the base or not, perhaps sometimes flowering in the first year (one collector describes it as annual), 0.9–1.5 m, often straggling through bushes, young stem and branches with short white hairs, glabrescent with age. Main stem and branch leaves broadly ovate to lanceolate, alternate, 1–4.5 x 0.6–2.5 cm, obtuse to subacute, ± densely shortly white-pilose; petiole slender, to 1 cm long; upper leaves rapidly reducing, narrowly lanceolate to linear. Inflorescence a large, open panicle of alternate, axillary, simple or branched spikes each with a zigzag, very fine and capillary, thinly pilose axis. Flowers sessile. Tepals green: outer 2 lanceolate, 4–4.5 mm, 3-nerved, the outer 2 nerves very wide, densely furnished with long, silky, forwardly directed hairs, otherwise glabrous or the midrib also pilose, hyaline margins narrow; inner 2 broadly rhomboid with extremely broad, bluntly angled hyaline margins, with scattered long hairs along the midrib, lateral nerves slender; middle tepal with one broad hyaline margin, the other side with a long-pilose, thick lateral nerve as in the outer tepals, and sometimes the midrib more sparsely pilose. No pseudostaminodes, filaments flat and strap-shaped. Style c. 1.75 mm, slender. Capsule ovoid, 2–2.5 mm.
