Horsetail was named for its bristly appearance. The genus name Equisetum is derived from the Latin words equus, meaning horse, and seta, meaning bristle. Other names for horsetail include shave-grass, bottle-brush, and paddock-pipes.
Another gymnosperm phylum is Gnetophyta. This phylum only has three genera: Welwitschia, Gnetum, and Ephedra. Welwitschia mirabilius, the only species in its genus, is a very weird looking plant. It looks like a big pile of leaves that were dumped on the ground. It is only occurs in the Namib Desert in Africa.
