30 ANNALS OF SCOTTISH NATURAL HISTORY 



wishing it may obtain more information regarding the bryology 

 of Perthshire. 



The following list is largely taken from a reference 

 manuscript book of what may be called a Moss -Flora of 

 Britain by my father, the late Mr. John Sadler, Edinburgh. 

 I have, however, added many species and localities, which I 

 have found principally in books. Some mosses may be 

 extinct in the localities given, as it is between 20 and 30 

 years since many of them were gathered. Still they will be 

 of historical interest. The whole list must be looked upon 

 as a " contribution " only to the Moss-Flora of Perthshire. 

 There are about 260 species and varieties enumerated in this 

 list, which I have arranged according to Hobkirk's " Synopsis," 

 1873, as probably being the book, after Wilson's " Bryologia 

 Britannica," by which they were determined. There are 

 found on Ben Lawers alone quite 200 species and varieties ; 

 and probably all the rest of Perthshire could not add another 

 hundred to this number. Most of the mosses of Mr. Sadler's 

 large collection are now in the Herbarium of the Royal 

 Botanic Garden, Edinburgh, where they may be consulted.
