light-greoii fruit ; but this dries yellowish, and so loses most of 

 its distinctness. 



Poa Balfouri Parn. var montana (Parn.). What I believe to 

 be this was found in small quantity on the Argyllshire side of Ben 

 Laoigh ; it is being grown in the garden. Prof. Hackel so named 

 a very similar grass from the Perthshire corrie, many years ago. 

 *Glyceria declinata Breb. Not uncommon about Dalmally. 

 Woodsia alpina Gray {hyperborea Br.). Rare on Meall nan 

 Tigearn ; Cystopteris montana Desv. also occurs there in several 

 places. 



SHORT NOTES. 



Erophila virescens Jord. in Scotland, &c. — Last year Mrs. 

 E. S. Gregory, of Cambridge, sent me fresh specimens of this 

 plant from Whinnie Brae, near Galashiels, v.-c. 79. Selkirk, and 

 from the banks of the Tweed, Melrose, v.-c. 80. Roxburgh ; these 

 are the first that I have seen from North Britain. In May of 

 this year I took part in three excursions, conducted by Dr. C. E. 

 Moss and Mr. E. W. Hunnybun, and observed this species about 

 Mildenhall, Icklingham, and Cavenham, v.-c. 25. W. Suffolk ; near 

 Gamlingay, v.-c. 29. Cambridge ; and plentifully near Woodwalton 

 and Ramsey Heights, v.-c. 31. Huntingdon ; so that it is probably 

 frequent in the Eastern Counties. — Edward S. Marshall. 



Alnus glutinosa (See Journ. Bot. 1907, pp. 125, 163). — It 

 would appear that this name has been unnecessarily rejected and 

 A. rotundifolia unnecessarily substituted by several recent nomen- 

 clators, as the following citation of synonyms shows : — 



Betida Alnus var. glutinosa Linn. Sp. PI. 983 (1753). 



Betula glutinosa Linn. Syst. Nat. ed. 10, ii. 1265 (1759). 



Alnus rotundifolia Mill. Abridgement Gard. Diet. 6th ed. (1771). 



Alnus glutinosa Gaertn. De Fruct. ii. 54, t. 90, fig. 2 (1791). 



It is clear that the two citations from the works of Linnaeus 

 refer to the same plant — our common Alder, for the designatory 

 phrase {Alnus rotundifolia glutinosa viridis, from Bauhin's Pinax, 

 p. 428) is the same in both cases. Again, it has been universally 

 admitted that Gaertner delineated this plant ; and, indeed, his 

 descriptions and figure of the fruit and his citations leave no room 

 for doubt. Gaertner uses the earliest trivial name, and puts the 

 plant in its accepted genus. It is clear therefore that his combi- 

 nation, Alnus glutinosa, must stand, and that Miller's must be 

 relegated to synonymy. — C. E. Moss. 



Centunculus minimus in Cornwall. — In the Banksian 

 Herbarium at the British Museum, I have recently found two 

 specimens of Centunculus minimus L., labelled in Banks's hand : 

 " Cornwal. near Penzance, Mr. Lightfoot, 1774, in moist places." 

 This is certainly the earliest record of the plant for the county. 

 Mr. Davey was unaware of the existence of these specimens, as in 

 his recently issued Flora, of Cornwall he cites Courtney, in the 

 Penzance Guide, 1845, as the first recorder of Centunculus in Corn- 

 wall. — A. Bruce Jackson.
