SOME NEW OR NOTEWORTHY SPECIES REPORTED FOR 
OHIO IN RECENT BOTANICAL LITERATURE. 
Otto E. Jen'nixgs. 
Having in mind the considerable extent of the current 
botanical literature relating to the flora of the northeastern 
United States one is justified, perhaps, in assuming that verv 
few of the botanical readers of the Naturalist have access to 
more than a small part of such literature as might occasionally 
contain references to the flora of Ohio. For this reason it has 
seemed desirable to call attention to some new or otherwise 
interesting species which have more or less recently been accred- 
ited to Ohio, in order that Ohio botanists may be placed on the 
look-out for such species and further desirable information thus 
be brought to light concerning their distribution and occurrence.' 
1. Eriophorum viridi-carinatum (Engelm.) Fernald. 
Mr. Fernald distinguishes this species from E. polystachyon 
L., with which it appears to have been variously included by 
many American botanists, as follows: 
“Midrib of the scale prominent only below the membranaceous 
tip; leaves triangular-channeled above the middle; the upper sheaths 
dark-girdled at the summit.'' E. polystachyon L. 
“Midrib of the scale prominent, extending to the tip; leaves flat, 
except at the very tip; the sheaths and bracts not dark-girdled.'' 
E. viridi-carinatum (Engelm.) Fernald. 
For the range of his new species Mr. Fernald gives “ Bogs and 
wet meadows, Newfoundland to Saskatchewan and British 
Columbia, south to Connecticut, New York, Ohio, Michigan, 
Wisconsin, and said to follow the mountains to Georgia.” 
Among the many specimens designated as typical there is one, 
without a definite locality, for Ohio, ‘‘Ohio (Sullivant).” It is 
highly probable that other specimens of this speeies are to be 
found in Ohio collections. 
In his interesting article on Certain Polygonaceous Genera,- 
Prof. Greene says: ‘‘A diligent study of much material from 
almost all parts of the United States, occurring in the herbaria 
under the name of Polygonum Muhlenbergii, more recently 
denominated P. emersum, has shown that this also is an aggre- 
gate of species, some of them strongly marked, others less so. 
They differ one from another markedly as to leaf outline and 
also as to the attitude of the foliage, the leaves in some spreading
