I never saw the Mentha in flower, and my deceased esteemed friend 

 Mr. William Jackson for once informed me that he had never seen it 

 either, although he had often botanized in the Sidlaw district ; but its 

 flowering period (if my memory serves me rightly) is stated in the 

 ' Forfarshire Flora ' of Mr. Gardiner as August, September, October, 

 and it would be useful, as well as interesting, for local naturalists to 

 pay the station a visit during these months, for a series of years, and 

 ascertain how often it does flower. 



I may add that the plant grows abundantly by the wayside ; but 

 nowhere on the undisturbed natural heathy ground around, and this 

 circumstance may form a slight additional objection to its nativity, if 

 the other is sustained.

Notice of a New Locality for Anacharis alsinaslrum, Bab. [Udora, 

 see ante, 387], By Thomas Kirk, Esq. 



A few days ago, being in the neighbourhood of Watford, North- 

 amptonshire, I paid a visit to Watford Locks, on the line of (I believe) 

 the Junction Canal, thinking that as the locality is on the same line 

 of canal as Foxton Locks, the Anacharis might be found in the re- 

 servoirs attached thereto. As soon as I arrived within sight of the 

 reservoirs, I noticed that the further end of the upper one was covered 

 with what at that distance appeared to be a species of Potamogeton, 

 or Myriophyllum, but which on a closer inspection proved to be Ana- 

 charis alsinastrum, Bab. A further search showed it to be abundant 

 in all four of the reservoirs ; in some places being as much as eighteen 

 inches or two feet below the surface of the water, and in others, more 

 particularly in the upper reservoir, floating on the surface, but very 

 abundant in all four. 



Although I searched diligently during the short time I spent at the 

 locality, I could not detect the least vestige of fruit. The stems are 

 two feet or more in length, and the whorls of leaves much farther 

 apart than in a Leicestershire specimen in a state of fructification, 

 which I possess through the kindness of the Rev. A. Bloxain. That 

 gentleman, however, thinks it a similar species. Probably the diffe- 

 rence is only owing to the season in which the specimens were gathered.
