MOSSES OF THE WEST RIDING OF YORK. — 329 
that before long we shall find that form, as I am informed that it is as 
frequent as cymbifolium in other localities where that species is found. 
Fissidens exilis has been found at Todmorden, as ortul 
vinealis, id it is probable that others may yet turn up. Atrichum 
erispum (James) Se nae Wils. MS.) has been found both at 
Saddleworth and Todmorden. 
the new division “of the adunca group of Hypnum we have as 
yet found only the typical form H. aduncum of L. & Dill. (Z. 
exannulatum, Giimb.) ; but I have little doubt that most if not all the 
others will yet be found. The species which has generally been 
> gana, under the name of H. aduncum, L., is really only a small 
form of Kneifft ; ee according to the most recent researches “4 
Dr. Braithwaite, who some months ago examined the original s 
nym, an ri e 
aduncum be retained. This species differs from Knerfii by its much 
more falcate leaves, which are striate, rather strongly nerved nearly 
to the apex, with the basal cells larger a and inflated, and gradually 
distan 
striate, only thinly nerved for about two-thirds their length, with the 
basal angles decurrent excavate, of lax subquadrate cells, those 
above hehe elongate rectangular. The other species of this group 
are H. Sendtnert, Sch., which is var. «. hamatum of H. aduncum of 
ry. Eur., with its var <r Wilsont; H. ape po Lindb. = 
pellucidum, Wils. MS., and 4H. ancy var. tenue, of Bry. Brit., and 
HT, intermedium, Tandeces err Coss chp. 
These forms are all sufficiently distinct to rank as true species, and 
a little study of the various forms will soon enable any bryologist to 
distinguish “a readily.
