State Rank Reason (see State Rank above)
Lycopodium clavatum occurs in Montana on the eastern edge of its distribution in northwestern North America (FNA 1993). Populations appear stable, though it appears to be under-collected in herbaria. Current data on locations and population sizes are needed.
Shoots to 20 cm, solitary, often with short, arm-like branches. Leaves spreading or ascending, 3–6 mm long, narrow, entire-margined with hair-like tips. Strobili 1–4 cm long, 2 to 4 spreading or ascending on a branched peduncle sparsely set with yellowish bracts. Sporophylls broadly lanceolate, dentate with a hair-like tip. Similar in stature to the more common L. annotinum, but the long leaf tips are distinctive. One collection from Flathead Co. (C.L. Hitchcock 1868, MONTU) has a solitary strobile but otherwise appears to belong here (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX)
