Some plants of New York 

 RoBKRT T. Clausen 



Since the publication by Muenscher and Clausen (1934) of 

 some notes on the flora of northern New York, further collecting 

 in various parts of the state has yielded a number of interesting 

 items which are here listed with annotations. These notes may 

 be considered supplemental to those of 1934, also to the Bio- 

 logical Survey Reports by Muenscher (1935, 1936, & 1937) 

 and Mc\'augh (1938). Names of collectors most frequently cited 

 are abbreviated as follows: C, R. T. Clausen; Cu, O. F. Curtis, 

 Jr.; M, W. C. Muenscher; 5, S. J. Smith; T, Harold Trapido; 

 and W, \V. C. Wilson. Unless otherwise noted, all collections 

 are in the herbarium of the Department of Botany, Cornell 

 University.

 1935) from Lake Champlain, Clinton Co.; Harris Lake, Essex 

 Co.; Upper Saranac Lake Outlet, Franklin Co.; Piseco and Cat-

 Pond, Warren County. The writer has examined material from 

 all localities cited by Muenscher except Upper Saranac Lake 

 Outlet. He also has studied the following additional collections: 

 Middle Saranac Lake, Franklin Co., 1929, M, Manning, and

 W. W. Rou'lee; and Three Mile Bay, Oneida Lake, Oswego Co., 

 1927, M 16804. 



As observed by the writer in the Stoner Lakes, plants of 

 /. Tuckermanni appeared much like small specimens of /. 

 echinospora, but had the leaves decidedly recurved. The mega- 

 spores vary from being irregularly reticulated to having jagged 

 crests.
