This variety requires extreme care in cultivation, strong lightbeing fatal to its beauty. When well-grown it is perhaps the mostdelicately beautiful of British Ferns. Some of the happiest resultshave been obtained under treatment suited to filmy ferns, to whichindeed in appearance it bears no slight Athyrium filix-fcemina, vat. kalothrix 284 BRITISH FERNS XI Regale (Barnes)Barnes. (Raised) ft. 6 in. Raised by Mr. Barnes from splendens, and worthy of its name,—the nearest approach to a real crested plumosum,—though it bearsspores ;—in colour a clear golden green,—some of its seedlingspromise to be even better than the parent, if that be possible. There is something in the cresting of Athyriums which seemsdestructive of the true plumose character,—perhaps it is that a Ferncannot think of too much at one time,—however, the fact remainsthat hitherto, in spite of the efforts of all the most skilled manufac-turers, the two characters, in their perfection, have not yet beencombined. J. Wilson, of Bowness, can show seedlings from aplumose Athyrium, in every stage from simple plumosum to perfectcristatum ;—the plumose character being unmistakably visible whenthe plants are but slightly crested, but fading away exactly inproportion
