492 SHORT NOTES. 



was a strong, liassocky plant, with the gUimes of a much darker 

 brown than I have ever seen in C. imlpina, but resembling it in 

 general appaarance. Owing to the early time of year at which 

 both gatherings were made, no fruit was present ; they were, in 

 fact, hardly in full flower. — Edward S. Marshall. 



PoTENTiLLA NORVEGicA L. — In two or three localities near to, and 

 on the Middlesex side of, the Thames, between Staines and Lale- 

 ham, I have observed this plant for some years past; but at the end 

 of August, in the present year, I have found it also on the Surrey 

 side of the river, growing sparingly on fallow laud near Tliorpe Lee, 

 Egham. Mr. G. Claridge Druce, to whom I sent specimens, states 

 that he has collected this species in Berks and in Bucks. — E. 

 Ferguson Shepherd. 



Euphrasia gracilis Fries. — On Sept. 13th, during the present 

 autumn, whilst looking over the vegetation covering a portion of 

 the northern limits of Chobham Common, N.W. Surrey, my atten- 

 tion was attracted by the appearance of a Euphrasia, characterized 

 by its minutely delicate details of inflorescence and bracts, which 

 was quite new to me. My forwarding freshly-gathered specimens 

 of this to Messrs. F. Townsend and G. C. Druce resulted in both 

 these gentlemen readily concurring as to identity with the above- 

 named species. — E. Ferguson Shepherd. 



NiTELLA opaca IN WORCESTERSHIRE. — Mr. James Groves has 

 kindly looked at and determined as above a plant I gathered at 

 Newland, near Malvern, on July 20th. It was growing in con- 

 siderable quantity in a small meadow pond. It is, I believe, new 

 to the county. — Kichard F. Towndrow. 



The Mosses of the Upper Dovey. — The following mosses, col- 

 lected in the watershed of the Upper Dovey durnig the twelve
