Two of the above speeies, Marsilca quadrifolia and Azolla carolln- 

 iiuiti, are, the latter certainly and the former in all probability, in- 

 troduced. The Azolla seems to have been first collected in a pond 

 in Forest Park, Springfield, Mass., in 1892, by Mrs. M. L. Owen 

 and in 1896 was reported as spreading. From information kindly 

 furnished us by Dr. W. II. Chapin, it now appears to be extinct. 

 There is no other New England locality for it on record.
