Sceptridium
Sceptridium is a genus of seedless vascular plants in the family Ophioglossaceae, closely allied to the genus Botrychium. It is also closely related to the genus Botrypus. Sceptridium species are commonly called the grape-ferns.
These plants are small with fleshy roots, and reproduce by spores shed into the air. They differ from the moonworts in having at least some sterile fronds, and in the fronds being bi- or tri-pinnate ; and from Botrypus in being evergreen, or at least winter-green and having the non-spore-bearing part of the frond long-stalked.Species
