The most beautiful and delicate fern is certainly Adiantum pe- 

 datum., with palraately divided fronds. 



J*olypodiuvi vnlgare is useful for coveiing rocks. 



Woodwardia Virginica and W. aiigustifolia are SilsoornRmenta.\. 



The larger species of Aspleniuin, such as angiistifolmyriy thelyp- 

 teruides, and Filix-foeiuina, are quite showy ; of the last named there 

 are numerous varieties in cultivation. 



Woodsia Jlvensis can stand more sun than any other fern that I 

 know. 



C'/stopteris bidbifera has long and arching fronds. 



Dicksonia pxmctilobxda soon forms a mass of delicate light green 

 sweet-scented fronds. 



The half-hardy kinds require to be grown in a cold frame having 

 a northern aspect ; with those we must also class all ferns that are 

 in fact hard}', but owing to their delicacy or small size should be 

 grown with the half-hard}' ones. Plants of this class are Pnly- 

 podium incanum^ P. falcatum, and P. Californicum, Gymnogramnia 

 triangularis., and some species of Nothochlcena, Cheilanthes, Pelloea., 

 and Woodsia; also Allosurus aa-ostichoides, the lovely Adiantum 

 Capillus- Veneris, Scolopendrium vidgare., Asplenium Trichomanes, 

 A. ebenum, A. viride, A. Buta-muraria, A. septentrionale, A. mon- 

 tamim, and the curious Walking Fern Camptosorus rhizophyllus ; 

 with others. 



The greenhouse kinds are very showy and ornamental, but more 

 expensive to keep than the two sections above named. Poh/podium 

 aureum is a noble plant with very large glaucous fronds. P. plamula 

 has neat arching fronds of dark green color. P. Phyllitidis has 

 straight undivided fronds. 



Acrostichum aureum is a stately and showy fern with large and 

 thick fronds. 



Pteris longifoUa and P. Cretica are good well-known plants. 



xidiantum emarginatum and A. pilosum are good atUlitious to our 

 greenhouses. 



Woodwardia radicans has a thick stem and very large fronds. 



Anemia Mexicana and A. adiantifoUa are interesting plants. 



Nephrolepis exaltata is very show}' with its long and narrow 

 fronds. 



If desired, some of the species of Pellaea, Cheilanthes, and 

 Nothochliena may also be grown .successfully in this section. 



The only remaining class is that of 



Gkeenhouse Plants. — Here we may bring together various
