This rare species seems to be represented by specimens collected by Mary 
Strong Clemens in Lake Lanao, Mindanao, No. 215, February, 1906, s. n., 
April, 1906. The specimens are sterile, however, and accordingly the iden- 
tification is not absolutely certain. Mr. A. W. Bennett agrees with the 
above identification of the material.
