Cash : On Cinclidium stygium.

We take the liberty to enclose a few specimens which we are not just 

 satisfied about. No. 1 is what we had named Grimmia ovata at the time 

 we made our list. We found it only in small quantities, and the fruit 

 was very young. We have found it in a better state since. We think it 

 does not agree with your specimens of G. ovata ; perhaps it is the G. 

 Doniana. [Mr. Wilson makes a note that it is this latter species.] We 

 hope you will forgive us disappointing your expectations. No. 2 is that 

 which we had named Pterogonium gracile, but we find that it does not 

 agree with your specimens of that plant. We have never seen it in fruit, 

 but we think the leaves — at least some of them — are two-nerved at the 

 base. [Mr. Wilson's note is that this moss is Hyp. catenulatnm ; some 

 of the leaves were two-nerved.] No. 3 we have thought was Trichosto- 

 mum microearpum, [Mr. Wilson writes " Not so "] but the capsules 

 appear rather cylindrical in shape. No. 5 we have thought was Didy- 

 modon flexifolium [which Mr. Wilson confirms], but we have not seen it 

 in fruit. No. 6 is what we have called Didymodon rigidulum — [perhaps 

 an aquatic variety — W.], but you will see that the capsules are cylindrical. 

 No. 8 we think may be Hyp. albicans — ['* Probably "], but we have not 

 seen it in fruit. No. 9 is what we have named Hyp. murale — [H. con- 

 fertum], but we think that the leaves are serrated. 



" Perhaps you will think that we are taking too much liberty in pre- 

 senting these specimens in their present condition, but we trust that you 

 will excuse us, as we have no other person to apply to for information on 

 this subject ; and should we ever be able to render you any service in 

 procuring for you any plants in our vicinity, we shall ever feel happy to 

 do so.

"John Haistworth. 

 " William Greenwood. 

 " John Nowell." 



In a P.S. the writers ask for exact directions to Weissia tricJiodes 

 {Brachyodm ti'ichodes), near Littleborough. 



I do not know what became of Hanworth and Greenwood, but 

 Nowell continued to correspond with Wilson, and in a letter dated 

 October, 1838, he wrote : — "I have the pleasure to inform you that 

 this summer I have had a botanical ramble to Malham and Ingle- 

 borough. I found Cinclidium dygium in considerable plenty in the 

 station on Malham Moor \ but unfortunately the finest of the fruit had 

 been eaten off by something, so that I did not get very many specimens 

 in fruit ; but I got a good supply in a barren state. I find the S.yp. 

 rugulosum in two or three places in the neighbourhood of Malham, but 

 not in plenty. I found Weissia pmilla [Seligeria pusilla) on shady 

 rocks in Gordale, and also on Ingleborough, but very sparingly. The 

 following I found in Ingleborough : — Tdraplodon mnioides (very rare),
