. Our ferns in their haunts; a guide to all the native species. Ferns. THE HE polypodies belong to the largest of the fern families. There are nearly four hundred species in the world, mostly in the Tropics. Only five species extend into northeastern America, and three o f these are considered by many botanists to belong to a closely allied genus which they name Phegop- teris. This name, it may be said, was once the name of a section of the genus Phegopteris DryopUris. Polypodijtlll and tllOSC wllO call our plants species of Phegopteris, simply consider this section worthy of gene

Polypodijtlll and tllOSC wllO call our plants species of Phegopteris, simply consider this section worthy of generic rank. As in the true poly- podies, the fruit dots are without indusia of any kind but the phegopterids differ in having the fruit on the backs of the veins while in the Polypodiiims they are op the ends. In Polypodiiivi, too, the stipes are jointed to the rootstock, while in P/iegopterts, in most oi ourcommon ferns, they are not. Phegopteris is also very closely al- lied to the wood fern genus, differing principally in the lack of an indusium. In habit, also, the species are rpuch like the wood ferns and it is probable that they will.
