Many club-moss gametophytes are mycoheterotrophic and long-lived, residing underground for several years before emerging from the ground and progressing to the sporophyte stage. [4] Lycopodiaceae and spikemosses (Selaginella) are the only vascular plants with biflagellate sperm, an ancestral trait in land plants otherwise only seen in bryophytes.
Club moss spores and teas from plant leaves have been used since ancient times in both American Indian and European cultures. Medicinal uses included treating urinary tract problems, diarrhea and other digestive tract problems; relieving headaches and skin ailments; and inducing labor in pregnancy.
The club mosses commonly grow to be 5–20 cm tall. [4] The gametophytes in most species are non-photosynthetic and myco-heterotrophic, but the subfamily Lycopodielloideae and a few species in the subfamily Huperzioideae have gametophytes with an upper green and photosynthetic part, and a colorless lower part in contact with fungal hyphae.
Lycopodiella inundata is a species of club moss known by the common names inundated club moss, [2] marsh clubmoss [3] and northern bog club moss.It has a circumpolar and circumboreal distribution, occurring throughout the northern Northern Hemisphere from the Arctic to montane temperate regions in Eurasia and North America.

By comparison "lycopod" or lycophyte (club moss) means wolf-plant. The term "fern ally" included under Pteridophyta generally refers to vascular spore-bearing plants that are not ferns, including lycopods, horsetails, whisk ferns and water ferns (Marsileaceae, Salviniaceae and Ceratopteris).
