Fig. 84. 4.7. f. Jameszi (pinna). Fig. 85. A. f. А Kalon (pinna). 
Jamesn (Fig. 84).—A very fine, flat, crested form raised by Mr. 
James from his corymbiferum. 
Karon (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. АП plants we have seen have a slight tendency 
to revert, sometimes entire fronds, but more usually parts of 
pinne only, to a plumose form, presumably the parental form, 
which, from the fact that Kalothrix, when sown, yields true progeny
