Dr. Suitu’s Remarks on Hypericum calycinum. .. 967 
of Bauhin, described in his Prodromus, p. 130, from Burser's 
specimen, and therefore to be ascertained by the herbarium of 
the latter at Upsal.. On turning to Linneus’s own copy of Bau- 
hin, I found a mark indicating that he had made this inquiry, 
and the result is recorded in an unpublished manuscript note in 
the first edition of his. Species Plantarum to the following effect: 
* The true Linnean Hypericum Ascyron is the same with that of 
Burser. Its stem is perfectly straight and altogether herbaceous. 
If therefore the plant of Wheeler be shrubby and inclining, it is 
certainly another species.” 
In consequence of. this discovery of Linnaeus, the synonym of 
Wheeler is not given under H. Ascyron in the second edition of 
Sp. Pl., though that of Morison is still retained, Linneus not 
having perceived that Morison figures Wheeler’s plant, while the 
latter part of his description only belongs to it, the former being 
transcribed from Bauhin’s Prodromus. Such faults are common in 
writers who work on the plan of Morison, and he errs also in men- 
tioning Mount Olympus as the place where Sir George Wheeler 
gathered his plant. But though Linnzeus rejected Wheeler's 
synonym for his H. Ascyron, he has not either referred it to any 
other old species, nor described it afresh as a new one, at least 
in the Sp. Plantarum. In his Mantissa indeed, p. 106, he has de- 
scribed the species in question by the new name of Hypericum 
calycinum, but without any synonym; and he had now so totally 
forgotten his former note, and the reference to Wheeler's Journey, 
that he gives North America, with a doubt, as the native coun- 
try of his calycinum. ‘This was a mere guess, devoid of all founda- 
tion. The specimens of this species in his herbarium appear to be 
garden ones ; so does the original authentic one of his H. Ascyron, 
though to the latter he has pinned a plant raised by Gronovius 
from Pennsylvanian seed, which is H. pyramidatum of Hort. Kew.
