nical rarities, especially Orchidex, from the vicinity of Mon-— 
treal. These cases were, upon their arrival in autumn 1823, 
placed by our able curator, Mr Murray, in a frame, into 
which the air was freely admitted during the winter and spring, 
and early this summer they have presented such a spectacle of 
rare American orchideous plants in blossom, as, except in their 
native places of growth, there has perhaps hardly ever been 
witnessed. 3 Be lees 
Hitherto Pursu is the only author who has described this 
species of Habenaria, although Nurrauu speaks of it as an 
inhabitant of the Alleghany Mountains, of Pennsylvania, and 
the banks of Lake Erie. The range of this plant’s growth 
extends, therefore, from Virginia to Canada, from which latter 
country I have also received dried specimens of it from MrCiEec- 
HORN and Mr Goutpir. From New York, too, the plant has 
been transmitted to me through the kindness of Dr Torrey, 
and from Boston by F. Boott, Esq. It may surely, therefore, 
be reckoned among the more common species of this family in 
North America: indeed, it is so well known that Pursu states 
the inhabitants to be generally acquainted with it under the 
name of All-heal. 3 
The species most nearly allied to the present individual, is 
the very fine plant which Mr GoupieE discovered in the island 
of Montreal, and which is described under the name of Habe- 
naria macrophylla in Mr GoupIE’s “ Account of new and 
Rare plants detected in Canada during the year 1819,” in the 
6th volume of the Edinburgh Philosophical Journal. 
It is with much surprise I find that my friend Dr Torrey 
of New York, in a letter which he had the goodness to write 
to me upon the subject of Mr Gompir’s paper, considers the 
Ef. macrophylla, of which he judges of course only by the de- 
scription, to be the same with the HZ. orbiculata of Pursu, 
notwithstanding that the differences between these two plants 
are fully and satisfactorily pomted out in the Memoir in ques- 
tion. It will suffice here to mention, that the H. macrophylla 
is twice the size of the present individual in almost all its parts ; 
and that the anther is at each angle at the base, prolonged into 
a projecting horn. 
Should I not succeed in my expectation of obtaining H. ma- 
crophylla in a living state from Canada, I shall undoubtedly 
publish a figure of it from some well preserved specimens in my 
herbarium, which have been given to me by Mr Goupiz.
