The Scottish Naturalist. 255 



"* Borago officinalis L. On a rubbish-heap on the Links (August, 



1878, J. T.) ; also in Guide for Methlic and Cullen. 

 Echinospermum Lappula Lehm. In sand-pit near old Aberdeen 



(August, 1878, J. T.) ; probably a casual introduction. 

 Symphytum asperrimum Bieb. Roadside near Echt (September, 



1879, J.T.). 



* S. officinale L. Occasionally near Aberdeen, at St. Cyrus, &c. 



(J. T.); probably introduced by cultivation. 



* Cynoglossum officinale L. Recorded in Guide from several 



places. 



Chenopodiace.e. 



* Beta vulgaris L. Recorded bv Dickie as once found on the 



Inch. 



* Chenopodium Bonus-Henricus L. Not scarce by roadsides and 



near houses throughout the district. Formerly cultivated. 



* Atriplex littoralis L. Recorded by Dickie as formerly on the 



Inch. 



POLYGONACEiE. 



* Polygonum Bistorta L. Is a doubtful native as far as my 



observations go, the localities in which it occurs being such 

 as to leave doubt whether it is not an escape from former 

 cultivation ; it easily establishes itself. 



Urticace^e. 

 None of the species of this Order seem to be true natives of 

 this part of Scotland. Both Urtica dioica and, still more 

 markedly, Urtica urens are closely associated with man, nor do we 

 meet with them away at any distance from signs of past, if no 

 longer actual, human occupancy ; hence they would seem to have 

 been introduced unintentionally by man. 



* Parietaria officinalis L. On several old buildings (Guide), where 



it had been planted. I have it from Inverugie and from 

 Tolquhon Castle. 



Humulus Lupulus L. In hedges in various places — e.g., near 

 Balgownie, at Cults, and elsewhere near Aberdeen ; pro- 

 bably planted almost wherever it occurs. 



Ulmus montana Sm. and U. suberosa Ehrh. Are not infrequent, 

 but are either planted, or the produce of planted trees. 



AMENTIFERjE. 



Castanea vulgaris L. Is not rare — e.g., at Cults, Benholm, &c, 

 but only where planted.
