The summer and winter states of many aquatics are widely different. 

 I observed that when water was drawn from the reservoirs into 

 either of the locks, the force of the current detached small sprigs of 

 the Anacharis, which were carried through the slime into the lock, 

 and thence into the body of the canal, so that in all probability other 

 localities exist in the canal itself, as well as in reservoirs belonging 

 to it. 



The circumstance of this locality being connected with that at Fox- 

 ton Locks, will strengthen the opinion of those botanists who regard 

 the Anacharis as an introduced plant. I think there can be little 

 doubt that one locality was supplied from the other ; as apparantly 

 only female plants are found in each, but how it was originally natu- 

 turalized in either of these artificial situations I can scarcely conjec- 

 ture. Altogether, I think all the recorded localities in this country 

 seem rather to prove it an introduced plant than a true native.

Notes on the Flora of Dumfriesshire. By William Stevens, Esq. 



The accompanying observations on the rarer portion of the Dum- 

 friesshire Flora, have been made on various occasions during the last 

 twelvemonth's residence in that county. I do not, of course, pretend 

 to give a complete list of all the rarities which may occur in the dis- 

 trict, the species here enumerated being only such as have come un- 

 der my own actual observation; but such as they are, they may contain 

 some little not unworthy the notice of those who feel interested in the 

 distribution of our native Flora. I have given them in the form of an 

 arranged list of species, so that any remarks upon the general features 

 of the county would be superfluous, but it will be seen that in a bo- 

 tanical point of view it is by no means uninteresting. 



Ranunculus Lenormandi. This is of frequent occurrence in pools 

 and ditches about Thornhill ; particularly abundant in a ditch by the 

 road-side near the ruins of Carlaverock Castle, on the Solway coast, 

 also in the neighbourhood of Moffat. 



Tlialictrum alpinum. Plentiful in a rocky ravine near the Saddle- 

 back, and upon other hills in its vicinity. 



Subularia aquatica. Loch Skew, intermixed with Littorella lacus- 

 tris, which latter is by far more abundant.
