Psilotum is a genus of fern-like vascular plants. It is one of two genera in the family Psilotaceae commonly known as whisk ferns

• They lack true roots and leaves are very reduced, the stems being the organs containing photosynthetic and conducting tissue.

• There are only two species in Psilotum and a hybrid between the two. They have stems with many branches and a synangium with three lobes rather than two.
