124 TRANSACTIONS OF THE [Sess. lxxxi 



mosses collected in an excursion between Manuel and 

 Linlithgow : but as precise localities are not given, and as 

 the excursion evidently covered ground both in Stirling- 

 shire and Linlithgowshire, this list has not been quoted 

 here. Some of Messrs. Bell and Sadler's specimens are, 

 however, in the Herbarium, Royal Botanic Garden, Edin- 

 burgh, and will be found quoted as from that source. The 

 Census Catalogue of British Mosses (1907) enumerates 

 166 species and varieties as occurring in V.C. 84. The 

 sources of these records appear to have been the afore- 

 mentioned works, Edinburgh Herbarium, and unpublished 

 lists by Mr. W. Evans and Mr. J. M' Andrew. Mr. Evans 

 and Mr. M'Andrew have kindly placed a great deal of their 

 data at my disposal, and the definite localities for their 

 contributions to the Census Cat. have been given here 

 whenever known. No definite locality or reliable authority 

 has been found for some of the Census Cat. records ; 

 these have been included here and ascribed to the Census 

 Cat. Li a paper in Scot. Bot. Rev., vol. i (1912), p. 202, 

 Mr. M'Andrew contributed 24 additions to the Census 

 Cat. list for V.C. 84. These have been quoted here with, 

 in some cases, amended descriptions of localities as supplied 

 to me by Mr. M'Andrew. 



The following list enumerates 216 species and varieties 

 as compared with 190 recorded in the Census Cat. and 

 Mr. M'Andrew's published list of additions. Doubtless 

 additions will still be made : the Sphagna, for example, 

 have been very imperfectly worked, and several fairly 

 common mosses are still unknown from this county. 



My own investigations in the county were pursued until 

 the outbreak of war, in conjunction with Mr. S. E. Brock. 

 The latter's absence on military service has prevented 

 more recent co-operation, but a considerable amount of the 

 material used here was gathered in our joint field-work. 

 I am indebted to the Regius Keeper for enabling me to 

 examine certain specimens in the Herbarium, Royal Botanic 

 Garden, Edinburgh ; to Mr. Evans and Mr. M'Andrew For 

 much kind help and information ; to Mr. R. H. Meldrum 

 and Mr. D. A. Jones for verifying many of my specimens; 

 and to Mr. J. A. Wheldon for naming or confirming several 

 Spltagna and Hypna (Ifar/ddid).
