ME to MN south to northern GA and OH.
AbundanceFrequent in the Mountains, but uncommon in the Piedmont. The website editors suggest a State Rank of S4.
HabitatMontane bogs, fens, marshes, streamsides.
PhenologyFlowering and fruiting July-September.
IdentificationWoodland Bulrush resembles Woolgrass Bulrush (S. cyperinus), but lacks the rusty color of the spikelets, the bristles are barely longer than the seeds (vs. very much longer than the seeds in that abundant species), and the leaf sheaths (at least on the lower leaves) are red and give the stem a red-banded look that Woolgrass Bulrush lacks.
Taxonomic CommentsNone

Note that the genus Schoenoplectus has been split from Scirpus and includes plants with sessile spikelets, or with spikelets with a few branches (vs. open, widely branching inflorescences). Most of our Schoenoplectus species appear to have no leaves (exceptions are S. etuberculatus and S. subterminalis), whereas Scirpus taxa have well-developed basal and stem leaves.
