SCOTTISH RUBI 171 



these in the county of Hereford alone), with a general 

 average of 40. The average of forms as yet recorded with 

 certainty from Scottish counties is but little above i i, while 

 the highest number (for West Perth and Mid Perth) is only 

 32. Several vice-counties are almost unrepresented. Omit- 

 ting those counties in which fruticose Rubi are known to be 

 scarce, Mr. Rogers states that (besides R. idceus, which 

 has been found in all the vice-counties) of forms accurately 

 and clearly determined, Peebles and Haddington yield i 

 each, Selkirk and Edinburgh 3 each, Roxburgh 4, Lanark 

 and Forfar 6 each, Berwick 7, Dumfries, Fife, and Elgin 8 

 each, while the records for most of the other counties are 

 evidently very defective. 



Owing to the numerous changes in nomenclature result- 

 ing from recent researches in the genus, the older floras and 

 lists cannot now be relied on except for R. idtzus, R. 

 saxatilis, and R. chamcemorus, and possibly for R. corylifolius 

 in the collective sense. " Rubus suberectus " and " R. 

 rhamnifolius " of these lists may each represent any one of 

 several forms now distinguished from each other. Even the 

 lists of " Topographical Botany," ed. 2, cannot be implicitly 

 followed. Yet I have thought it may help towards a more 

 accurate and full investigation of the Rubi in Scotland if 

 what is already on record for each vice-county and for each 

 form is brought together and placed at the service of those 

 interested in the Flora of Scotland. In what follows I 

 have endeavoured to do so, drawing the information from 

 numerous sources, and indicating briefly for most forms 

 the name of the observer, and where the record may be 

 found. Most of these indications are given in full when 

 first mentioned, and abbreviated in later references. 



Some works and papers refer to several vice-counties or 

 to the whole country, and are frequently referred to. These 

 are H. C. Watson's " New Botanist's Guide " (issued for Scot- 

 land in 1837), his "Topographical Botany," ed. 2, 1883, 

 a list by Mr. Rogers in the "Journal of Botany" in 1895, 

 his "Handbook of British Rubi," published in 1900, in 

 which the earlier records were revised and corrected, and 

 a paper by him " On the Distribution of Rubi in Great 

 Britain," in the "Journal of Botany" (April 1902), and the
