State. Localities comparatively few. Common in the southern 

 part, Clutc." While this does not exclude the western part of 

 the State, it leaves the impression that the presence of the fern 

 there was not known to the compiler. Mr. Day gives it in the 

 Buffalo catalogue, but does not indicate localities. This is ex- 

 plained as meaning that the range of a plant is throughout the 

 area considered, one with a radius of fifty miles, taking Buffalo 

 as the center. In the Rochester list it is said to be rare, and 

 three stations are mentioned : "Glen east of Float Bridge," Holley 

 and "The Gulf," Genesee county. Of these I am familiar with 

 the last only, situated in the town of LeRoy. It is a gorge in the 

 corniferous limestone, on which the fern grows associated with 

 Poly podium vulgare and Camptosorus rhizophyllus. I collected 

 the spleenwort here in i860 and again in 1895, «o that it bids fair 

 to persist in this wild but quite frequented gorge. Whether the 

 other stations are on limestone I do not know, but I have found it 

 on a different substratum on "Thomson Ledge." in northern 

 Ohio, a cliff of millstone grit, or sandstone matrix with abundant 

 quartz pebbles. Here it was associated with Polypodium vulgare 

 and Cystopteris fragilis. 



But one more plant of the article requires notice, Equisetum 

 palustre L., a representative of a more northern flora in general. 

 A station is given it in "swamps near Buffalo," on the authority 

 of Judge Clinton. A definite locality is assigned it by Day : 

 "Squaw Island, Niagara river." One station is noted in the 

 Rochester list, "Margin of Genesee river, near Lake Ontario."

A NEW SPECIES OF EQUISETUM. 



By Willard N. Ci«ute. 



While returning from a trip after specimens of Equisetum, 

 recently, I passed a colony of these plants on a hillside in the 

 suburbs of Joliet, 111., and gathered a bundle of the stems for 

 study. At the time I supposed the species was Equisetum hyemale, 

 but upon comparing the stems with specimens of hyemale from 

 several other near-by localities it became very evident that except 

 for fairly close resemblance in the cross section of the stem, they 

 differed greatly from this well-known species. Since the distribu-
