Selaginella
Selaginella is the sole genus of vascular plants in the family Selaginellaceae, the spikemosses or lesser clubmosses.

This family is distinguished from Lycopodiaceae (the clubmosses) by having scale-leaves bearing a ligule and by having spores of two types. They are sometimes included in an informal paraphyletic group called the "fern allies". "S. moellendorffii" is an important model organism. Its genome has been sequenced by the United States Department of Energy's Joint Genome Institute. The name "Selaginella" was erected by Palisot de Beauvois solely for the species "Selaginella selaginoides", which turns out (with the closely related "Selaginella deflexa") to be a clade that is sister to all other "Selaginellas", so any definitive subdivision of the species into separate genera leaves two taxa in "Selaginella", with the hundreds of other species in new or resurrected genera.

"Selaginella" occurs mostly in the tropical regions of the world, with a handful of species to be found in the arctic-alpine zones of both hemispheres.
