Selaginella

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Selaginella is a genus of plants in the family Selaginellaceae, the spikemosses. Many workers still place the Selaginellales in the class Lycopodiopsida (often misconstructed as "Lycopsida"). This group of plants has for years been included in what, for convenience, was called "fern allies". Some workers have used the class Isoetopsida for both the spikemosses and the quillworts, even though the name Selaginellopsida A.B. Frank 1874 has priority over the name Isoetopsida, which was not published until 1885. Priority does not apply above the rank of family. The preferred modern term for the Lycopodiophyta, including Selaginella, is lycophytes. S. moellendorffii is an important model organism, and its genome was sequenced by the United States Department of Energy's Joint Genome Institute.
