Dist: The species is widespread in temperate North America; var. acutus is restricted to e. North America. ID notes: Schoenoplectus acutus var. acutus is very robust, up to 3 m tall, the round stems arising from thick horizontal rhizomes. Near the top of the stem is an inflorescence with generally erect to arching branches.
Schoenoplectus tabernaemontani (synonym: Scirpus validus) , a similar species, has as much as 8% sugar and 5.5% starch in rhizomes, but less than 1% protein (Harrington 1972). The rhizome (underground stem) is used for the black element in basket design. Rhizomes are obtained by digging around the plant and following them out from the parent plant.
Rhizomes 5–15 mm diam. Culms cylindric, 1–4 m × 2–10 mm. Leaves 3–4, all basal; sheaths often dark reddish proximally, front membranous-translucent and splitting, orifice adaxially deeply V-shaped; blades 1–2, C-shaped to dorsiventrally flat in cross section, usually much shorter than sheath, distal blade 8–120 × 3–7 mm, margins often scabridulous.
