BOTANICAL SOCIETY OF EDINBURGH. 



Dec. 10, 1846. — Professor Balfour, President, in the Chair. 



A letter was read from M. Lange and other Danish botanists, 

 offering to supply Scandinavian specimens in exchange for British, 

 and transmitting a catalogue of the Danish Flora, with the regulations 

 of the Scandinavian Association for the exchange of botanical speci- 

 mens. In the list there are 1285 Phanerogamous species enume- 

 rated, 263 of which are not found in Britain ; and thirty-nine species 

 of Ferns, of which six are not British. 



The following communications were read : — 



1. Dr. Balfour read an account of a botanical trip w r hich he had 

 made with some of his pupils to Clova, Glen Isla, and Braemar, in 

 August last. Dr. Balfour alluded in an especial manner to the Al- 

 pine Flora of the British Isles, the Scandinavian type of Prof. E. 

 Forbes, and illustrated it by a complete series of specimens, arranged 

 according to the natural system on pasteboard, so as to be seen at 

 one view. He noticed Prof. Forbes's theory as to the mode in which 

 the plants migrated at the glacial epoch. He also alluded to the 

 geological nature of the district visited, which is the richest in Bri- 

 tain as regards Alpine species, and the character of the Flora on the 

 different kinds of primary rocks, especially granite and mica-slate. 

 Specimens of the rarer species collected during the excursion were 

 exhibited, among which the following are interesting as having been 

 found in new localities, or rediscovered in old ones : — Carex rupes- 

 tris, abundant in Glen Dole, the specimens being unusually large ; 

 Poa Balfourii, near the falls of the Whitewater, and also in Glen 

 Isla and on Lochnagar; Poa ccesia, in Glen Isla; Poa laxa, and the 

 variety flexuosa of Parnell, Lochnagar and Glen Dole ; Luzula arcu- 

 ata, Lochnagar ; Saxifraga rivularis, in several new stations on Loch- 

 nagar, some specimens six inches long ; Gentiana nivalis in a new 

 spot in Glen Isla, specimens varying from ^th of an inch to six 

 inches in length ; Ranunculus acris, var. pumilus, Wahl., Lochnagar ; 

 Phleum alpinum, rocks near Loch Brandy ; Carex vaginata, abundant 

 on Ben na Muick Dhui ; Carex curta, var. alpicola, more correctly 

 C.Persoonii, near the summit of Lochnagar; Woodsia hyperborea, rocks 

 in Glen Phee ; Hieracium nigrescens, Ben na Muick Dhui ; and H. 

 inuloides in Glen Clova. 



Dr. Fleming expressed doubts as to the correctness of Prof. Forbes's 

 theory regarding the migration of the Scandinavian Flora, and no-
