366 ORTHOTRICHUM ANOMALUM. [December, 



" I expect however that the Scottish 0. anomalum will be found 

 to correspond generally with your specimens from Aberdour. I 

 have the same thing, I believe, from the Abbey Craig, near Stir- 

 ling, gathered by the late Dr. Lyle, but in a state much past 

 maturity/' — W. Wilson, in litt. ad J. B. W. 



" The pedicel in O. anomalum, H. and T., is twice as long, and 

 twisted.— W. Wr

" My dear Sir, — I have received both your letters, which 

 have, I assure you, afforded me the most lively pleasure and 

 gratification. Immediately after the receipt of your first com- 

 munication, I applied myself at once to the study and careful 

 examination of all the Orthotricha anomala (so called) in my 

 herbarium. In this task I was engaged during the whole of 

 last week, and at the expiration of that time had not entirely 

 completed my researches. This investigation has however led 

 to results the most important and interesting for the Bryolo- 

 gical Flora of Europe. In addition to your species, (the one from 

 Aberdour,) which is evidently distinct from that of Bry. Eur. and 

 which is in fact the one most widely distributed over the Conti- 

 nent of Europe, I have established the existence of two new spe- 

 cies, both of which are peculiar to Norway. I have also most 

 rigorously and carefully determined O. Pylaism from authentic 

 specimens sent to me by De la Pylaie himself, and have moreover 

 established its essential difference as a species from O. Breutelii 

 of Hoppe, with which Miiller had united it, and which is truly a 

 good species, as is also O. Barthii of Liudblom (?). We have then 

 now, as you will see, no less than six distinct species in the section 

 including 0. anomalum, instead of one ! I amperfectly satisfied 

 that these six species are all to be met with in Europe, and have 

 no doubt of their validity. In the next parcel of Mosses which 

 I hope soon to have the pleasure of sending you, I will enclose 

 specimens for you, illustrative of each. As to the O. anoma- 

 lum of British authors, I have also found in my collection some 

 examples of it, gathered on the Continent, more particularly in 

 the south of Europe and near Strasburg ; but in them the peri- 

 stome is not so regularly developed as in the English examples
