Vll 



country, where it has always been confounded with the still 

 more abundant Poterium Sanguisorba. I am not competent 

 to decide on its specific distinctness from that familiar plant, 

 but am willing to put faith in the opinion of those who have 

 thus decreed. 



Tencrium Botrys has again been found at Boxhill, and MessrA 

 Borrer and G. S. Gibson pronounce it a true native (PhytoP 

 iii. 707). 



Bromus arvensis, for which other species have been so often mis- 

 taken, has been found introduced in corn-fields in the same 

 locality, and by the same energetic botanists. 



New localities have been reported for the following rare, or perhaps, 

 more correctly speaking, little-known species. 



Filago spatulala has been found by Mr. Varenne (iii. 385) at In- 

 worth, in Essex. 



Udora canadensis has occurred in a number of localities almost 

 sufficient to induce the conclusion that this plant has been 

 hitherto most negligently overlooked. The first of these lo- 

 calities, in the Lene, near Nottingham, is recorded by Miss 

 Kirby (iii. 387), who remarks that Mr. Mitchell's attention 

 was attracted to the circumstance from seeing pieces of the 

 plant scattered about the meadows after a flood. Mr. Kirk 

 (iii. 389) has found it in great abundance at Watford Locks, 

 in Northamptonshire. Dr. Johnston found it (iii. 541) at the 

 lake at Dunge Castle, so far back as 1842, and again in 

 abundance in 1848, in the Whitadder or its tributaries : 1 

 believe these localities are in Berwickshire. And last, Mr. 

 Brown (iii. 647) informs us that it forms large submerged 

 masses in the Trent. Fashion, and perhaps the love of no- 

 velty, have changed the name of this plant from Udora cana- 

 densis to Anacharis Alsinastrum. Is there sufficient botanical 

 ground for the change ? Dr. Johnston says (1. c.) " I have 

 specimens of Udora canadensis from Dr. P. W. Maclagan, 

 gathered in Detroit River, July, 1848, and they exactly re- 

 semble our Whitadder plant, as found at the Newmills sta- 

 tion :" other excellent botanists express the same opinion.
