Technical Description: Rhizome: very slender, elongate. Culms: few together or solitary, 0.2-2.5 dm tall, erect, slender, stiff, exceeding the leaves, very obtusely triangular. Leaves: few (2 or 3 with well developed blades) 4-15 cm long, 1.0-1.5 mm wide, involute, erect, ascending, light green. Bracts: none. Spike: solitary, staminate above, with 1-6 perigynia below, conspicuously jointed to the rachis. Flowers: monosporangiate. Scales: the staminate; few, appressed into a terminal cone, the pistillate; early deciduous, ovate, light brown, 4.0-6.0 mm long. Perigynia: subulate or linear-lanceolate 6.0-7.0 mm long and 1.0-1.5 mm wide, scarcely inflated, glabrous, membranaceous. Beak: hyaline tipped. Style: protruding, persistant. Stigmas: 3, short, slender. Achene: linear-oblong, about 2.0 mm long and 0.75 mm wide, trigonous, occupying the lower third of the perigynium, yellowish brown.
Diagnostic Characteristics: Spike borne singly on culm, bisexual, pistillate basally, staminate at the summit. Achenes trigonous, stigmas 3. Perigynia elliptic or oblong to globose, ascending.
Duration: PERENNIAL
Reproduction Comments: n=23, 38. Periginia propelled 1-2 feet by compression of a spongy base and sudden loosening of the attachment at the absicission layer.
Ecology Comments: Always in association with sphagnum, often with tamarack, thuja, black spruce, and chamaedaphne.
Palustrine Habitat(s): Bog/fen
Habitat Comments: Sphagnum bogs.
