of these; one and the same frond may display all three types of 
cutting ; the spores invariably yield the same inconstant form. 
C. готлозом. Raised by Mr. Clapham ; shows mainly the inter- 
mediate type on somewhat leafier lines. 
C. pLumosum.—Raised by Mr. Barnes; has broader and leafier 
fronds, but finely cut. 
C. TRICHOMANOIDES.— Та this, we believe by constant suppression 
of the normal fronds, an almost constant form has been arrived at 
by Messrs. Backhouse, of York, only showing the finest-cut type 
with very little reversion ; very beautiful. 
CRENATUM (Fig. 203).—Found in several places ; а wide-fronded 
form, the subdivisions being bluntly toothed. 
CRISTATUM (Plate XXV and Appendix No. XLVII).—Found in 
Ireland by Mr. H. S. Perry and others; a very prettily tasselled 
form. 
C. MoRLEYII.--Similar to cristatum, but less markedly tasselled. 
ELEGANTISSIMUM.—See Cornubiense. 
GLOMERATUM.—Found in Dorset by Mr. Mullins; a curious, 
ramose, and subcristate form, no two fronds alike, but no reversion 
to normal. 
GRANDICEPS ForsTER, с. Fox (see Appendix Nos. XLII and 
XLVII).—The finest forms of cristatum, heavy bunch crests, but 
distinct. 
G. PARKER.—Found in Somerset by Mr. Parker ; a splendid form, 
bearing heavy, much-branched heads on almost bare stalks, with 
the tips of the cresting prettily crisped ; the finest crested form 
of all.. 
Hurcutsonu.—Reported as found by Mr. Hutchison in Wales, 
but its history is obscure, and as it is so exact a replica of Cornu- 
biense in all respects, we are inclined to doubt its wild origin. 
LoNGIPINNATUM.—Found by writer at Killarney ; very long and 
narrow pinnae, fronds consequently very wide, six inches and 
more. 
MACROSORUM.—A very fine deltoid form, with very long and 
pinnatifid basal ршиа, the rest serrate, sori extra profuse and 
conspicuous ; found by writer at Minehead. 
MACROSTACHYON.— Found in Ireland by Mr. O'Kelly; fronds 
have wide lateral lobes, and terminate with a very wide and large 
one set on end, forming a broad caudate tip.
