FERNERIES.

surrounding the fertile. I have occasionally observed fronds of the 

 0. regalis partaking somewhat of a similar character. 



The Cystopteris bulbifera (fig. 883) is thoroughly acclimatized with 

 me. It multiplies by division, by spores, and by little bulbils formed in 

 the axils of the leaves. It is a fern which should be grown in quantity. 



Of the Polypodiums, the P hexagonopterum, a good companion 

 plant to the oak and beech fern, is well acclimatized. The P. Braunii 

 is perfectly hardy. 



The Pteris scaberula (fig. 884) lives in my outdoor exotic fernery, 

 but has not flourished. It grows vigorously when planted out for the 

 summer, and is most elegant. I exhibited a plant treated in this way 

 at one of the meetings of the Horticultural Society, which delighted the 

 lovers of ferns, and which received thp special certificate of the Society. 

 The common Pteris serrulata has survived many years of intense 

 frost, and the P. rotimdifolia (fig 883 a) is far more beautiful out of 

 doors than when grown in confinement, but yet will not stand the 

 severest winters.

Of foreign Lastraeas or Nephrodiums, L. curvata, L. Opaca or 

 L. varia, L. Sieboldii, and L. patens, all stand the severest winters ; and 

 of these L. curvata is particularly vigorous. There is a very fine plant 

 from Japan, L. Standis/tii (fig. 885), which will live out of doors, but 

 perhaps does better in a cold greenhouse. 



The two Woodw:ardia^, W. orientalis and W. radicans, have lived 

 with me many years, nevertheless the fronds have every winter been 

 cut down by frost. I do not doubt that in Devonshire and Cornwall
