๐งฌ Field Guide Specimen: Open Fir Clubmoss in the CRV Science Field Guide to log the specimen, see its place among the Diaphoretickes lineages in the Cladogram Explorer, and test your recall in the Red List conservation game.
Reproducing by Bulbils
Besides spores, the plant makes small bud-like bulbils in the leaf axils, which drop off and grow into new plants. This clonal reproduction is common in cold climates.
A Source of an Alkaloid
A related species, Huperzia serrata, is the source of huperzine A, an inhibitor of acetylcholinesterase that has been studied for Alzheimer's disease. Clubmosses make many alkaloids.
Old Lineage
Lycophytes diverged from other vascular plants more than 400 million years ago. See Common Clubmoss.
