On mountain slopes and summits, North Carolina, espe-

Experience with the genus Hyperzcum in both the field and 
the herbarium, has convinced me that several of its groups are 
still quite imperfectly understood. One of these groups is 
that represented by Hypericum prolificum and H. densz- 
fiorum. When compared with one another these two species 
are sharply defined, but specimens from the southern Alle- 
ghenies have been accumulating in our herbaria which, 
although placed in one or the other of the above mentioned 
species by some authors, must be rigidly excluded in order 
to preserve natural limitations. The specimens referred to 
represent a species which seems to be peculiar to the higher 
peaks of both the Blue Ridge and Alleghenies proper where 
I have observed it on several mountain summits. It was 
collected before the middle of the present century, but mature 
fruit was not seen until Mr. A. M. Huger secured it on 
Grandfather Mountain during the summer of 1896. 
flypericum glomeratum may be separated from Hypericum 
prolificum by the small size of all its organs, especially the 
smaller corollas, and by the terminal inflorescence. Both of 
these characters suggest Hypericum densiforum, but the or- 
gans of this species are still smaller, the corolla being only 
one-half as large and in place of the open cymes the inflo- 
rescence is characteristically congested. 
The following specimens should be placed here:
