ISOETES AMESII: A CORRECTION. 



Through failure to see proof of Gilbert's list of ferns and 

 allies of New York in the October Bulletin, there has arisen 

 an unfortunate confusion of names. This species is given as a 

 straight synonym of /. riparia Canadensis Eng. (now /. 

 Canadensis (Eng.) A. A. E.). It should have read Canadensis 

 in part," it being segregated from Engelmann's specimens at 

 first referred to that species. Subsequent study proved Amesii 

 not to be safely separable from the polymorphic /. saccharata, and 

 in Rhodora for November, 1903,1 described it as /. saccharata var. 

 Amesii. This description appeared before the October Bulletin 

 and would be the correct name by priority. — A. A. Eaton, Ames

EQUISETUM V ARIEG AT UM IN CONNECTICUT. 



In the Bulletin (Vol. XI, No. 2), in an article on "Bquisetum 

 scirpoides in Connecticut," I made the statement that E. variega- 

 tum had been reported from that State, but that probably Scir- 

 poides had been mistaken for it. I have since received a speci- 

 men of variegatum from Mr. C. H. Bissell, which he collected on 

 the banks of the Housatonic river at Cornwall, Conn. Mr. Bissell 

 informs me that this species also has been collected at Canaan, 

 and he thinks it probable that it will be found in other places 

 along the Housatonic. — A. Vincent Qstnun, Amherst, Mass.
