The species indicated in the previous lists are the less fre- 

 quent ones only of the mountain ; eleven of them have been 

 added to the British flora within the last four years, viz, : — 



*SphagQum Miilleri. *Mnium spinosum. 



teres. ^tTimmia norvegica. 



Girgensohnii. ^t Leskia nervosa. 



Campylopus corapactus. *Hypnum sulcatum, Sck. 



Bryum latifolium. ^ Bambergeri. 



*Tortula fragilis. 



And of these, seven (marked *) , together with the following 

 (whose discovery dates further back), viz. 



Myurella apiculata, Hypnum cirrhosum, 

 Hypnum plicatum, Oakesii, 



have, at the present date, no other known station in Britain 

 than Ben Lawers. 



The only notable Perthshire alpine species which appears 

 to be absent is Hypnum hamulosum, Bry. Eur. [H. hamulo- 

 sum /S. micranthum, Wils. Bry. Brit.), which exists in great 

 profusion towards the summit of Craig Challeach, near 

 Killin. 



Ben Lawers produces certainly i8o species (and pro- 

 bably many more), i. e. one-third of the whole known in 

 Britain. If the damp woods, rocks, and walls near the 

 bank of Loch Tay are taken into account, there is a great
