44 ANNALS OF SCOTTISH NATURAL HISTORY 



The following are the sources from which the records 

 have been derived 



The Herbarium at the Royal Botanic Gardens, Edin- 

 burgh, which I have had the opportunity of examining at 

 leisure, through the kind courtesy of Prof. I. B. Balfour. 

 This herbarium contains, besides several original specimens 

 of Taylor's of much value, the Greville Herbarium, and 

 specimens from the following Scottish botanists J. Cruick- 

 shank, T. Drummond, W. Gardiner, W. Gourlie, P. Gray, 

 W. Jackson, Rev. J. Kerr, G. J. Lyon, Dr. W. Nichol, 

 J. Sadler, R. M. Stark. 



Prof. Dickie's Herbarium at Aberdeen, which Prof. Trail 

 kindly sent me for examination. 



A duplicate collection of Alex. Croall's hepatics. 



The Herbaria of Charles Howie and of John Sim, 

 Strachan. The latter includes many specimens gathered by 

 the Rev. Dr. Fergusson, Fearn. 



A collection, mostly from Stirlingshire, gathered by the 

 late Col. Stirling and by Mr. R. Kidston, which Mr. M. B. 

 Slater very kindly gave me. 



Specimens, in several instances large collections, from the 

 following correspondents and collectors Messrs. W. H. 

 Beeby, H. N. Dixon, W. Evans, P. Ewing, W. J. Gibson, 

 Dr. T. F. Gilmour, Messrs. Symington Grieve, W. P. Hamil- 

 ton, J. T. Johnstone, D. Kennedy, Rev. D. Lillie, Messrs. J. 

 M'Andrew, J. Macrae, C. M'Intosh, Miss K. B. Macvicar, 

 Messrs. R. H. Meldrum, J. Michie, A. Murray, J. Murray, 

 C. Scott, G. Stabler, W. West, W. Young, and specimens 

 gathered by myself. The share which each has taken will 

 be seen when the account of the distribution is given. 



Of the forty-one vice-counties into which Scotland is 

 divided, there are four from which I have seen less than 

 forty species. These are Wigtown, Roxburgh, Banff, and 

 North Aberdeen, the last being a blank. When considerably 

 more than half the vice-counties have been recorded for a 

 species, the exceptions are given, and are printed in italics, as 

 done by Prof. Trail with phanerogams in his " Topographical 

 Botany." 



The sequence of the genera closely follows that of 

 Schiffner in Engler and Prantl's Pflanzcufaniilien.
