A new species of Selaginella in the S. apoda complex
Keyword(s):
A new species of Selaginella (Subg. Stachygynandrum), S. eclipes Buck, is described from the mid western United States and the Great Lakes area. It is similar to S. apoda but is characterized by dorsal leaves which have long, attenuate apices. The apices are usually hyaline, fragile, and unkeeled; the midrib extends into the apex. The strobilus is typically longer than that of S. apoda and the sporophylls are generally broader. The megaspores are laxly reticulate with broad muri and a pitted surface. Evolution within the S. apoda complex is discussed and a key to the species is given.
