WHITWELL: WEST YORKSHIRE MOSSES. 175 
There is also a variety rupestris which occurs on stones, rocks, and quarries, 
and is nearly twice as large. Frequent in North Oxon, and must be also in 
Craven. 
The var. estiva is rare, occurring in shady moist places, and hence ripening 
a month later. This is smaller than the common form. 
I am loth to suppose that I have been mistaken about these things all this 4 
rh but still am not unwilling to learn. If, then, it is not mzra/is, there 
wes the question—What is it? 
“Bat i in truth this is ‘ wrote sarkasticul,’ and I believe you may safely call your 
moss by that name. 
Your Brachyth. rivulare is, 1 think, correct, but much too far decayed to be 
worth anything. Here is a better specimen to compare. 
Iam glad 7. revo/uta pleased you, and now send 7. convoluta to match it. 
Yours very truly, 
H. Boswk i. 
Mr. Boswell sent me authenticated Zortula rigidula Dicks., and 
I do not wonder (my moss knowledge being so slight) at any 
confusion between the two species. 
The next letter has pleasant personal references to ourselves, 
and also gives my authority for the record of Bxyum ( Webera) 
albicans in the ‘Flora of West Yorkshire,’ for the Aire valley locality 
of Skipton Woods. The specimens, it should be mentioned, were
