SOME NEW OR NOTEWORTHY SPECIES REPORTED FOR 

 OHIO IN RECENT BOTANICAL LITERATURE. 



Otto E. Jennings. 



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 occasionallv 

 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 summits 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
