Hypericum boreale (Britton) Bicknell. In 1891 N. L. 
Britton* made brief mention of this interesting St. John’s-wort, 
regarding it as a variety of Hypericum canadense L. In 1895 
E. P. Bicknell discussed its relationships in a comprehensive 
paper in the same journalt, in which he raised the plant to spe- 
cific rank and showed that its affinities were with Hypericum 
mutilum L. rather than with Hypericum canadense. He credits 
it with a range from Maine and Nova Scotia westward through 
Canada and south in the mountains into Pennsylvania and New 
Jersey. 
Two plants collected by O. E. Jennings at Geauga Lake, 
August 22, 1903, and one sheet from Defiance County in the 
State Herbarium under Hypericum mutilum are referable to this 
.species. Its occurrence in two so widely separated counties ^ug- 
gests that it may be found to have a wide distribution over cen- 
tral and northern Ohio, and warrant the publication of a note 
calling attention to the characters by which it is separated from 
H ypericuni mutilum, which in general appearance it closely 
resembles. 
The two species are distinguished most easily by the character 
of the bracts, which in Hypericum mutilum are awl-shaped, and 
1-2 mm. long. In Hypericum boreale they are foliaceous, elliptic, 
three-nerved, and from 2-6 millimeters long, the lower being the 
the large.st. Also in Hypericum mutilum the mature capsules are 
ovoid, about 3 mm. long; the seeds oblong, about .2 bv .4 mm., 
while in Hypericum boreale the capsule is ovoid-oblong, 4 mm. 
long; the seeds oblong, .2 by .6 mm. 
Hypericum boreale also occurs still farther west in Wells 
County, Indiana, where it was first collected by Mr. Charles C. 
Deam, of Bluffton. It is found there almndantlv in peat bogs, in 
company with Triadenuni virginicum (L.) Raf., Sarracenia pur- 
purea L., Campanula aparinoides Pursh, and other characteristic 
bog plants. Defiance County, Ohio, is not far from the Indiana 
station. The specimens from Geauga Countv were growing in a 
bog also, as is shown by the plants of Sphagnum moss clinging 
to their roots. It probably occum in most of the peat bogs 
throughout the state. 
Camelina microcarpa Andrz. was collected for the second 
time in Ohio by Prof. W. A. Kellerman at Columbus. It was 
found in great abundance by a roadside near the city. The only 
other known station is at Painesville, Lake Countv.
