A word upon the authorship of the genus. Linnzus, as his 
manner is, writes “ Myosurus, Dill.” So, also, do Endlicher, Jus- 
sieu (except that he goes further back), De Candolle, Torrey and 
Gray, etc., etc. All¥this Mr. Greene must have overlooked, 
when, in his revision of MZyosurus, he reclaimed this genus for 
Dillenius in a special foot-note, and supposed that he stood 
alone. ‘ The practice of recognizing the genera of Tournefort, 
Dillenius, and the like (when adopted by Linnzus, or subse- 
quently taken up) is general, though not universal. Neverthe- 
less one can understand and appreciate the reasons which gov- 
erned the authors of the last Genera Plantarum, when they de- 
cided not to go back of Linnzus. Yet we prefer to follow a 
fairly established rule—to follow, indeed, the practice of Linnzeus 
himself. , 
I add a key to the species of AZyosurus so far as I now know 
them.
