From my gathering-s. 



auritum Moore. My specimens not so decided as some 

 gathered in Devonshire in 1886. Taken in several localities, 

 the four best (No.) 63 S.S.E., 107 S.S.W., 131 and 139 both 

 N.N.W., and from different localities quite a mile apart. 



bifidum Moore. Gathered once on a high bank under bushes, 

 May and June 1884, S.S.E., and there are several small 

 forms which seem as if tending towards cristatum, but are 

 not really that. Some fine specimens in Duddon Woods, 

 S.W. Cumberland, not gathered. 



crenatum Moore. This form not quite typical, found on a 

 wall, facing W., 154; and after two years of cultivation 

 ran into a poor serratum. The summer of 1887 (in which 

 I was much from home) killed it. 



cornutum Moore. Found on same wall as last and same 

 aspect. 154 B. I have grown the variety ever since 1885, 

 and it is fairly constant, sometimes exhibiting a tendency 

 towards crenatum and dentatum. Mr. Baker, to whom 

 a plant was sent, said it was the cornutum Moore, but 

 some of the variety men of to-day may not call it so. First 

 found, I believe, at Arnside by Crossfield in 1865. 



cristatum (? Perry ). The late John Ball, of Grange (the great 

 friend of Anthony Mason) gave me a small plant of this in 

 1893, and told me it had been gathered near Grange. 



dentatum Monkman. (154 A.) Same wall and aspect as 

 crenatum^ and again not quite typical. Length of frond, 

 including stipes, 1 in., breadth 4% in. 



? foliosum Wollaston. I think 140 (same wall and aspect) 

 may be referred to this, although I have not seen a properly 

 vouched specimen of foliosum. Length, stipes 3 ' 4 in., 

 frond c) 7 4 in., breadth 5 in. 



With these four crenatum , cornutum, dentatum, and 

 ? foliosum — is a form resembling very poor
