280 TRANSACTIONS AND PROOERDINGS OF THE [Sess. lxvii. 



buted a list of additions to the county records of Scottish 

 plants, compiled from the published notes of numerous 

 botanists, English as well as Scotch ; and among these 

 additional records a good many relate to south-east 

 Scotland. The flora of the county of Stirling has been 

 very carefully investigated by Colonel Stirling and Mr. R. 

 Kidston since the issue of the second edition of " Topo- 

 graphical Botany," and the additions discovered by them 

 have been published in the " Transactions of the Stirling 

 Natural History Society." As part of the county is in the 

 Clyde basin, some of the records from it may not refer 

 to the Forth valley, but these are not many. 



The flora of Perthshire in the Forth basin (West Perth 

 of " Top. Botany ") is among the better known in Scotland, 

 thanks to Dr. F. B. White's " Flora of Perthshire " (1898), 

 and to subsequent papers on Ritbi by Rev. W. Moyle 

 Rogers, and on Rosa by Mr. W, Barclay. 



The basin of the Tweed has been the scene of much 

 careful work, and its flora in Scotland has been made 

 known by J. V. Thompson's " Catalogue of Plants growing 

 in the vicinity of Berwick-upon-Tweed" (1807), by Dr. 

 George Johnston's "Flora of Berwick-on-Tweed" (1829-31), 

 and "Natural History of the Eastern Borders" (1853), 

 and in the excellent publications of the Berwickshire 

 Naturalists' Club, and in other scientific journals, as well 

 as in the works of H. C. Watson already referred to. 



In view of the length of time during which investigation 

 of the flora of the basins of the Forth and the Tweed has 

 been in progress, of the number of collections that have 

 been made, especially around Edinburgh, of the high and 

 well-deserved reputation of the botanists that have taken 

 part in the work, and of the numerous published books 

 and memoirs recording the results of their labours, it might 

 well seem that there can be little remaining uninvestigated 

 in either district, and that it is presumption in one that 

 has done so little field work as I in south-east Scotland to 

 criticise the labours of others. But the preparation of the 

 census of Scottish plants made me aware of the gaps in the 

 records for the several counties, and showed that it would 

 not be possible to prepare a flora for any county in the 

 country that could give a true and complete view of it at
