DUNDEE NATURALISTS' ASSOCIATION. 



Monday, Dec. 6th, 1847. — Mr. George Lawson, President, in the 

 chair. 



Mr. Jackson presented for examination specimens of the following 

 plants that had been sent him for the Association, by Mr. Alexander 

 Croall, and some interesting notes by Mr. Croall on the various species 

 were read. 



Pinguicula alpina, L. From the Moors of Rose-haugh, in Ross- 

 shire. From Mr. Croall's note accompanying the specimen, it would 

 appear that this very rare and interesting plant is on the point of ex- 

 termination, in consequence of the progress of cultivation in the district 

 where it grows. 



Bartramidula Wilsoni, Bruch & Schimper. From the head of 

 Glen Dole, Clova, Forfarshire (see Phytol. ii. 1017). 



Gymnostomum Donianum, Sua. From Cawdor burn, Nairnshire. 



Placodium plumbeum, Ach. From trees in Cawdor wood, Nairn- 

 shire. 



Mr. Lawson exhibited specimens of Cyphella muscigena, Fr. (de- 

 termined by the Rev. M. J. Berkeley), from the Den of Mains, and 

 Mr. Ogilvie produced several lichens from the same locality.
