Juncus pylaei Laharpe. Subgenus: Agathryon. Section: Juncotypus. Common Rush. Phen: Jun-Sep. Hab: Moist soil, bogs, marshes, swamp forests, margin of streams, ponds, lakes and swamps, low meadows; overlooked and probably more widespread and common than shown. Dist: Throughout eastern North America, south at least to NC and SC. The mapped distribution is unusually speculative, owing to past lumping with Juncus effusus.

ID notes:Similar to J. effusus but with the stems being coarsely and conspicuously ridged much like a fluted column.

Origin/Endemic status: Native
