SMALL-GROWING FERNS. 



27 



forming this class is contained in the genus Pellcea (Platyloma of commerce), 

 the representatives of which have pretty fronds, mostly of a glaucous hue, 

 handsomely shaped, borne on thin, wiry stalks, varying in colour from a 

 dark prune to shining black. Although a few of the stronger-growing kinds 

 among these are natives of Australia, the majority of them come from North 

 America, as do also most of the Cheilanthes and Nothochlamas of small 

 dimensions. It is obvious that, besides being highly interesting themselves, 

 the Ferns forming this section possess over many other stronger-growing 

 kinds an advantage which should not be overlooked, inasmuch as a greater 

 number of them can be accommodated in a given space; and the fact that 

 they do not require any more special attention than larger kinds should be 

 conducive to their more general cultivation, wherever a suitable place can be 

 made for them. 



A list is appended in which the best and most distinct species and
