56 ANNALS OF SCOTTISH NATURAL HISTORY 



(Jordan), Aberdeenshire and Shetland, form 2, Friesiamis (Jordan), 

 Shetland (Beeby). Specimens should be provided with rootleaves 

 and rootstock, as these afford the best characters for determining the 

 forms. The beak of the carpel should also be shown. 



The Moss Exchange Club Reports for 1899 and 1900 form 

 a pamphlet of 63 pages. Upwards of 5300 specimens of Mosses 

 and Hepatics were sent by members for distribution during 

 these years, and as far as practicable, these were submitted to 

 specialists to secure accuracy of nomenclature. The reports 

 enumerate the species distributed, with, in many cases, critical 

 notes by the specialists. These, along with the localities of the 

 plants, render the reports valuable to students of British Mosses. 

 Many of the records are from Scotland. Among the notes Mr. 

 H. N. Dixon states that specimens from Ben More in Perthshire 

 and other Highland localities, formerly distributed as Webera 

 annotina, have been recently determined by Dr. Hagen to be 

 W. commutata, Schimper.
