In the very unequal treatment by Diels in Die Naturlichen Pflanzenfarailien (Engler-Prantl), some 120 genera are recognized. A somewhat similar difference prevails in regard to tbemumber of species. The Synopsus Filicum of Hooker and Baker(1874), supplemented by Baker's New Perns (1892), recognizes some 2,700 species. It is the too common tendency in this work (1) to fail to rec- ognize many valid species which have been described by German and French botanists, and (2) to mass under one name very diverse sroups of species from distant i|uarters of the world— Jit- from 8 tu 10 species not infre- quently appearing as a single so-called "variable ; the number represented by thes^ omissions tne species recently described, the num- of Perns will approximate 4,000, and possibly exceed hat number. New forms are constantly coming in from he less explored parts of the world, and within the a,st few years several new species have been described rom the United States, including some from the bet- ter known portions. Of this number some 200 species are in occasional cultivation in America, but the spe- cies that form the bulk of the Fern trade do not exceed two dozen. In Europe several hundred species have long been in cultivation. Most of the species thrive best in the insular regions of the trop- ics, the island of Jamaica alone furnishing 500 species and Java nearly 600. About 105 species are native in the United States, representing some 35 genera; our native species are so widely dis- tributed that not more than from 25 to 50 will be found with- i
