Falcatum

J. Smith. Fig. 1199. Holly Fern. Pinna; glossy, ovate, falcate; the lower rounded or obliquely truncate at the base, 4-6 in. long, 1-2 in. wide. Japan, India. - The large thick glossy foliage makes it an excellent fern for decorations. One of the species used in fern-dishes and one of the few species which can be made to thrive under ordinary house conditions. Plants from the temperate parts of Japan will do well out-of-doors in the northeastern states if given slight winter protection. For another illustration, see article on ferns. C. Butterfieldii, Hort., is a form of this species differing in having the pinnae deeply serrate. C. Roch-fordianum, Hort., recently advertised, is a variety of C. falcatum with fimbriated leaflets Superficially these two forms resemble C. caryotideum somewhat, but the species are entirely distinct. It has begun to replace the original form in the dealers' stocks.
