BRITISH FERNS 



Fig. 84. A .f. f. Jamesii (pinna 



Fig. 85. A.f.f. Kalon (pinna). 



Jamesii (Fig. 84).— A very fine, flat, crested form raised by Mr. 

 James from his corymbifcrum. 



Kalon (Fig. 85). — Another handsome form raised by Mr. James 

 from corymbiferum ; this has the pinnules crested. 



Kalothrix. — One of the loveliest British Ferns ; fronds cut into 

 very slender, almost hair-like, subdivisions of silky lustre, whence 

 the name, which means " beautiful hair." Separately raised by 

 M. M. Howlett and Sim from a plumose form in Oxford Botanic 

 Gardens, but an identical form figures in the Herbarium there as 

 found wild, many years previously, in the Mourne Mountains 

 in Ireland ; a photo of this frond was kindly sent by Dr. Masters 

 to the writer. All plants we have seen have a slight tendency 

 to revert, sometimes entire fronds, but more usually parts of 

 pinnse only, to a plumose form, presumably the parental form, 

 which, from the fact that Kalothrix, when sown, yields true progeny
