Discussion
Ophioglossum nudicaule is much less common than O. crotalophoroides; they often occur together and are found in the same or similar habitats. The gametophytes of O. nudicaule are typical for the genus (M.R. Mesler et al. 1975). A given colony may be made up of small, medium, or large plants (W.H. Wagner Jr., C. M. Allen, and G.P. Landry 1984).
