Plant forming cushions to c. 50(–70) cm diameter (large cushions may be formed from the coalescence of several individuals). Leaf blade (1.4–)4–7(–9) mm long including a shortly acicular tip (0.3–)0.5(–0.9) mm long. Sepals mostly 2.5–3.5 mm long, predominantly white at anthesis (with a pale green median strip abaxially) but becoming pale green at fruiting, the apex occasionally cucullate, often with a small apiculus 0.1- 0.3(-0.4) mm long. Stamens (3-)5(-7.8) mm long. Ovary white to yellowish at flowering becoming pale green at fruiting; styles 1.5-3.5 mm long. Peduncles (1.1-)3-6(-12.7) mm long at fruiting; bracteoles (1.4-)2-3(-3.7) mm long with a short apiculate tip 0.1-0.3(-0.4) mm long.
