NOTES FROM THE OHIO STATE HERBARIUM. I. 



H. A. Gleason. 



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 

 niutiluni 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 ptiblication of a note 

 calling attention to the characters by which it is separated from 

 Hypericum mutilum, which in general appearance it closely 

 resembles. 



The two species are distinguished most easily b_\' 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 largest. 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 bv .G mm. 



Hypericum boreale also occurs still farther west in Wells 

 County, Indiana, where it was first collected bv Mr. Charles C. 

 Deam, of Bluffton. It is found there abundantly in peat bogs, in 

 company with Triadenum virginicum (L.) Raf., Sarracenia pur- 

 purea L., Campamda aparinoides Pursh, and other characteristic 

 bog plants. Defiance County, Ohio, is not far from the Indiana 

 station. The specimens from Geauga County were growing in a 

 bog also, as is shown by the plants of Sphagnum moss clinging 

 to their roots. It probably occurs in most of the peat bogs 

 throughout the state. 



Camelixa 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.
