DistributionHaywood County only; specimen in prep. (fide Alan Weakley, 2022). Note that prior to this collection, Weakley (2022) states: "This species was reported for NC by Lellinger (1985) and FNA, and is apparently indicated as occurring in NC on the range map in Mickel (1979); there is apparently no documentation for these reports, though the species occurs in Grayson County, VA, a county adjacent to NC."

Across nearly all of Canada, south to western NC, TN, NM, and AZ; essentially in the mountain regions in the central latitudes.
AbundanceExtremely rare; one recent collection. Based on this single collection, the species has recently (2022) been tracked by the NCNHP, as Significantly Rare, with a State Rank of S1.
Habitat"Swampy or moist coniferous forests, mountain forests, and exposed grassy or rocky sites" (Flora of North America website). In the VA, NC, and TN regions, in cold/cool, high elevation forests.
Identification"Strobili sessile, borne directly above densely leafy portions of upright branches; leaves acuminate to acute" (Weakley 2022), whereas the Lycopodium species have "Strobili borne on elongate, sparsely leafy peduncles borne at the tips of leafy, ascending branches; leaves with attenuate, hyaline hair-tips".
Taxonomic CommentsMost references consider it as Lycopodium annotinum, including NatureServe.
