MAN'S INFLUENCE ON INDIGENOUS FLORA OF ABERDEEN 179 



in a copy of Hudson's " Flora Anglica " ; and subsequently 

 purchased at a sale his copy of Lightfoot's " Flora Scotica," 

 with additional notes by him. Some of these notes give 

 evidence of the occurrence of plants in localities from which 

 they have long disappeared. He died in 1 8 1 o, aged 43. 

 His successor in the chair of Natural History was of very 

 different and inferior type ; but the investigation of the 

 plants of Aberdeen was continued by one of those taught 

 by Beattie, Dr. William Knight, who, though Professor of 

 Natural Philosophy in Marischal College, taught Botany 

 there, as lecturer, for a number of years. He published 

 little, but he left a great amount of manuscript on many 

 subjects. Among other notes are lists of plants observed in 

 various localities in and near Aberdeen, during excursions 

 of his classes and at other times. 



In 1836 appeared the first published work on the flora 

 of the North of Scotland, "The Northern Flora," Pt. I., 

 by Dr. Alexander Murray, including about a third of the 

 flowering plants. It is most careful and suggestive, con- 

 taining many personal observations, but the author's early 

 death prevented the completion of the work. The " Flora 

 Abredonensis " by Dr. George Dickie, in 1838, gave a list of 

 the higher plants of Aberdeen and of a district of about I 5 

 miles radius around; and it was followed in 1853 by "A 

 Catalogue of the Flowering Plants and Ferns growing in 

 the neighbourhood of Aberdeen, by Paul H. Macgillivray, 

 son of the well-known Professor William Macgillivray, who 

 had taught botany in Marischal College for some years 

 before his death in 1852, and had collected the plants of 

 the district. Dr. Dickie in 1860, just after his appointment 

 to the newly founded chair of Botany in the University of 

 Aberdeen, issued his " Botanist's Guide to the Counties of 

 Aberdeen, Banff, and Kincardine." 



In these various lists a number of localities within 

 Aberdeen are named under both native and alien species 

 where the plants do not (and often could not) now exist ; 

 but this applies chiefly to the rarer or more local plants ; 

 and the information they contain has been supplemented by . 

 the use of collections made prior to 1850 which have come 

 into my possession, or which I have been permitted to examine.
