into lanee- shaped segments. Increases freely by the side 

 underground shoots from the tufted rhizome or root-stock. Mr. 

 A. Stansfield, the nurseryman of Todmorden, has been very 

 successful in the discovery of varieties of this interesting Fern, 

 and about two years ago read a paper before the Botanical 

 Society of Todmorden upon the subject. Since that time we 

 have seen most of the sorts he had found, and they form a 

 very curious and pretty little group, not differing so widely 

 as do those of the Harts-tongue or the Lady Fern but still well 

 worth growing. First, then, we have concinnum (Neat), with 

 narrow fronds about 9 inches long; imbricatum (Overlapping), 

 the fronds short and ovate, with the pinnae " overlapping each 

 other so as to make the frond appear double," as Mr. Stansfield 

 says; crassicaule (Thick-stemmed), another small ovate-fronded 

 form; anomalum (Anomalous), the fronds in this case are fertile 

 above and sterile below ; ramosum (Branched), fronds branched 

 and crested at the points. There are many more varieties 

 which differ more slightly from the normal form or from each 

 other ; but those mentioned are the most distinct, and some 

 of the others we believe will hardly retain their characters 

 under cultivation. 



LOEINSOEIA. 



LOEINSOEIA AEEOLATA (Divided into spaces). This North- 

 American Fern is known also by the name of Woodwardia 

 arcolaia. It has two kinds of fronds ; the fertile ones being 

 much contracted. The barren fronds are broad and divided 

 nearly to the midrib, the divisions lance-shaped and toothed 

 along the margin. They rise to about a foot or 18 inches from 

 the soil, and stand somewhat erect. It has a thickish creeping 

 rhizome. 



ONOCLEA. 



This is a genus of Ferns from North America. There is 

 only one recorded species. The name Onoclea, is derived
