Mr. Geo. E. Davenport has recently issued a table showing the distribution of ferns in the United States. The number of species so far described is 155.

In distribution New York is the banner State, 52 species being found within its territory; Pennsylvania has 42; Vermont, 45; Michigan has 47; and Florida, by the help of tropical forms, 46. Only 2 species are found in Nevada, and 4 in Wyoming, 4 in the Indian Territory, 3 in Idaho, and but 9 in Iowa. Little Rhode Island has 34. Vermont has the greatest number of species as compared with territory, and may, on this account, lay claim to be the great fern State. Asplenium Trichomanes and Pteris aquilina have the widest distribution, being found, the former in 35, and the latter in 39 States. Polypodium vulgare has been found in 33 Stales. Adiantum pedatum occurs in 35 States. The rarest fern is Schizaea pusilla, in New Jersey. - Independent.
