A CONTRIBUTION TOWARDS THE MOSS-FLORA 



OF PERTHSHIRE. 



By T. D. SADLER. 



ALTHOUGH much has been written concerning the flora in 

 general of Perthshire, yet very few papers have been specially 

 devoted to its Moss-Flora. Many botanists have given, in 

 accounts of their excursions to various places in Perthshire, 

 the names of the interesting or rarer mosses with which they 

 have met ; and these accounts are to be found in several of 

 our scientific periodicals. 



The first, so far as I know, who wrote on the mosses of 

 Perthshire was William Gardiner, jun., of Dundee. In 1839 

 he wrote a short paper entitled " A Catalogue of Mosses, 

 collected in Forfarshire and Perthshire." In this paper he 

 embodies the results of two muscological excursions which 

 he had made ; and enumerates (including mosses of Forfar- 

 shire not found in Perthshire, at least in his time) 155 species 

 and varieties, belonging to 26 genera. This paper was not, 

 I think, ever published, and the manuscript is now in the 

 Library of the Royal Botanic Garden, Edinburgh, having 

 been presented to the Botanical Society by the author. Its 

 present scientific value is not very great. 



Among subsequent botanists who have given us lists of 

 mosses which they have gathered in this county, may be 

 mentioned Messrs. Holt, Sadler, and Sim, and Drs. Greville, 

 Lauder Lindsay, Stirton, and, last but not least, F. Buchanan 

 White. The publications in which their lists are chiefly to 

 be found are the " Scottish Naturalist," and the " Proceed- 

 ings and Transactions of the Botanical Society of Edinburgh," 

 and of the " Perthshire Society of Natural Science." I give 

 a list of eight of these papers further on ; so that any one
