Numerous collections at MONTU and MONT from 12 counties, including Lincoln, Flathead, Glacier, Missoula, Granite, Ravalli, Carbon, Stillwater, Lake, Powell, Teton and Lewis & Clark (October 2012).

Spike narrow, 4–7 mm long; male flowered portion above, 1–2 mm long; female flowers below, few. Perigynia narrowly elliptic, veiny, thick-stalked, 1.5–2.5 mm long, green, beakless; stigmas 3. Female scales green to tan, awn-tipped, shorter than the perigynia. Achene 3-sided, nearly filling the perigynium (Lesica et al. 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX
The only species in Section Polytrichoideae: Spike single, terminal, narrow, few-flowered, androgynous or all pistillate; stigmas 3, achene trigonous or round in cross-section, not filling the perigynium; rachilla absent; perigynium 5 mm or less, green, ascending, elliptic, beakless; lowest pistillate scales small, not foliaceous, mostly shorter than the perigynia; leaves numerous, slender, pale green. Fairly distinctive in overall appearance: pale green plant with very slender leaves, filiform stems, and small, single, terminal, androgynous spikes.
