Perennial herb with woody stolons up to c. 50 mm long, stems several from each stolon, the whole forming a many-stemmed tuft; stems 230–550 mm long, 1–2.5 mm diameter at base, simple to laxly branched, branches sharply ascending, strongly ribbed by raised vascular strands terminating in midribs of scale leaves and bracts, distantly leafy.
Perianth “weiss, aussen gelb” or “greeny white”; tube 1 mm long, 5 tiny (up to 0.1 mm) tooth-like glands alternating with the lobes; lobes 3–3.6 × 0.4–0.5 mm, linear, very acute, hood 0.6–0.8 mm long, margins inflexed, erose in upper part, densely white-bearded in lower.
Flowers often in long lax spikes, sometimes solitary, usually up to 6 on very short brachyblasts, on older stems brachyblasts crowded on very short simple or branched side shoots, sometimes with long new shoots developing at their apices.
Leaves all reduced to scales, c. 1–2.5 × 0.4–1.2 mm, increasing in size upwards and passing into floral bracts, lanceolate, acuminate, closely appressed, midrib strongly raised on dorsal surface.
Bracts and bracteoles 2–3 × 1–1.4 mm, ovate-acuminate, margins membranous, minutely erose-ciliate, keeled by strongly raised midrib, usually 3 only, rarely 4.
Stamens inserted at base of perianth lobes; filaments conspicuous, 1.5–2.2 mm long, briefly adnate to lobe; anthers 0.4–0.7 mm long.
Fruit 2 × 2 mm, probably buff-coloured when fully ripe, very strongly ribbed, very weakly reticulate.
Style 2.8–3.5 mm long; stigma reaching base of hood.
Pedicels wanting.
