 piece of work ; fifteen species in the following genera are figured :

Congress of Bota7iists— An IntcrnatianaL J. C. A. (Bot Gaz. 

 XV. 1 19-121). 



A suggestion that an attempt be made for an International 

 Congress in connection with the World's Fair. The Congress 

 might be held at the place of meeting of the A. A. A. S. or else- 

 where, according to local attractions. A number of foreicrn bota- 



nists arc pretty sure to be in America at that time, and if a 

 special occasion were made, doubtless others would attend. The 

 suggestion seems to us a timely one.

Croivfoot—The Yellow Water. Chas. E. Bessey. (Amer. Nat. 

 xxiv. 475). 



Alluding to Professor Greene's recent restoration of the name 

 R. lacustris, Beck and Tracy, to this plant, and to the fact pointed 

 out by that investigator that its duration appears to be unknown, 

 Dr. Bessey states that it probably grows about a year. This is 

 hardly its habit on Staten Island, where it certainly appears to 

 be perennial. The especial evidence that I have of this, is the 

 case of a small pond where it grew abundantly some years ago, 

 but bloomed only once In six years, and of another where I ob- 

 served the green and growing plant in March ot the present sea- 

 son. The plant which goes for var. terrestris may, however, be 

 an annual. There is opportunity for some nice observation here.
