WHITTIER, D.P., ŠTORCHOVÁ, Helena. The Gametophyte of Huperzia selago in Culture. American Fern Journal. 2007, 97(3), 149-154. ISSN 0002-8444. E-ISSN 1938-422X

Cultured gametophytes of Huperzia selago are dorsiventral and strap-shaped. They are basically the same as cultured gametophytes of other terrestrial Huperzia species and also essentially the same as gametophytes of H. selago collected from loose soil. These gametophytes are Type III gametophytes as characterized by Bruchmann in 1898.
