aware that it is a generally diffused, and, consequently, 

 an often described species. 

 In Scotland it is, I believe, 

 not uncommon; but I state 

 this with doubt, as, trusting to 

 procure specimens of E. poly- 

 stachyon, a plant supposed 

 very common (and with which 

 I also had confounded E. pu- 

 bescens), whenever 1 chose, 

 for my herbarium, I have 

 delayed from day to day, and 

 year to year, and can only, at 

 this moment, boast of a few 

 miserable morceaux ; some of 

 which, however, are E. pubescens. In England it has been 

 found on Wallington Moors by Mr. Trevyllian, and indicated 

 by him there under the name of E. gracile. From the neigh- 

 bourhood of Paris I have not yet received it, but I possess it 

 from Switzerland, under the name of E. latifolium ; and, from 

 the description (pedunculis scabris) given by Schrader and all 

 foreign botanists, including Roemer and Schultes, as well as 

 Sprengel's Systema Vegetabilium, that Swiss specimen appears 

 rightly named ; whence we must transfer the synonym of the 

 English Flora to E. pubescens, or rather we must adopt for 

 the species the name of E. latifolium, and reduce under it the 

 E. pubescens of Smith. From Canada I have also received a 

 specimen, under the name of E. angustifolium Pursh ,• but, as 

 I have at present no opportunity of examining the specimen 

 of that author, I dare not cite that as a synonym. 



With regard to E. gracile, it is always described with, and 

 ought to be readily distinguished by, the triangular leaves. I 

 have not, however, been so fortunate hitherto as to receive 

 from any correspondent abroad the plant which foreign au- 

 thors have described under that name, or its synonym E. tri- 

 quetrum ; but in the British specimens which I have examined, 

 found by Mr. G. Don on Ben Lawers, the leaves are de- 

 cidedly, particularly the radical ones, plane at the base, and 

 only triangular in their upper half; and, from the whole habit, 

 I feel inclined to refer it to E. latifolium (E. pubescens Sm,), 



It is, however, but justice to Dr. Smith, here to state that 

 I have seen neither Mr. Bruce's nor Mr. Holmes's specimens, 

 and that even the plant which I have received from Mr. Baird, 

 and which accords tolerably well with Smith's specific cha- 

 racter (he says the peduncles are downy; in my specimen they 

 are rather covered with close set, somewhat rigid, setulse, or
