1. Psilotaceae

   Psilotaceae is a family of fern-like plants consisting of two genera, Psilotum and Tmesipteris. The two genera are very different and in the past Tmesipteris has been placed in its own family, Tmesipteridaceae, but most classifications continue to place it in Psilotaceae. The relationships of Psilotaceae have been unclear, in part because the plants lack roots or true leaves, but recent molecular systematic studies suggest a relationship to the fern family Ophioglossaceae. The first genus, Psilotum, consists of small shrubby plants of the dry tropics commonly known as "Whisk ferns". The other genus, Tmesipteris, is an epiphyte found in Australia, New Zealand, and New Caledonia. There has long been controversy about the relationships of the Psilotaceae, with some claiming that they are ferns, and others maintaining that they are descendants of the first vascular plants. Recent evidence from DNA demonstrates a much closer relationship to the ferns, and that they are closely related to the Ophioglossales, in particular. All Psilotaceae share a few characteristics. They are vascular plants and they lack leaves, having instead small outgrowths called enations. The enations are not considered true leaves because there is only a vascular bundle just underneath them, but not inside, as in leaves. Psilotales also do not have true roots. They are anchored by rhizoids. Absorption is aided by symbiotic fungi called mycorrhizae.
