FERNS FOR WINTER. 



Some ferns grow much better in ferneries than 

 others and it is well to have this in mind when select- 

 ing ferns for that purpose. Of all our native ferns 

 there are probably none that respond so readily to this 

 method of growing as the common polypody and the 

 beech and oak ferns. They often grow so luxuriantly 

 that the older fronds have to be cut away to make 

 room for the new growth. Plant these by all means. 

 The curious little walking leaf is always an object of 

 interest and one of the best ferns for indoor culture. 

 Of the spleenworts, the ebony and maidenhair spleen- 

 worts are very fine and grow rapidly. The circular 

 tufts of the latter are just the thing for miniature 

 rockeries. Small plants of Nephrodium cristatuni, 

 nmrginalc, spinulostcm and acrostichoidcs can be 

 recommended and the two species of Cystopteris 

 should not be forgotten. The common maidenhair 

 ultimately sends up an abundance of fronds but 

 requires some time to get started. Many species of 

 our common ferns grow too tall and rank for the 

 fernery unless it happens to be a large one 

 but if one can secure a tiny specimen of some of 

 these they are very pretty. None show a greater con- 

 trast than the broad fronds of Onoclca scusibilis 

 among the much divided foliage of other species.
