comparing the three species. With the better material of S. 

 Georgianus now at hand I can add somewhat to the original de- 

 scription. The stem is usually a meter tall, and bears as many as 

 eight or ten leaves. The character of the sheaths of the leaves 

 seems to be variable and of little value. Its affinities seem to be 

 rather more with S. atrovirens than with S. polyphyllus. 



SCIRPUS SYLVATICUS L. 



A few large specimens of this species were collected in a small 

 brook at the northern base of Stone Mountain, at about 950 ft. 

 altitude, July 10 (no. 205), accompanied by Polygonum seta- 

 ceum Baldw. (no. 206). This is its southern limit, as far as known. 

 The locality is so near the perpendicular face of the mountain that 

 it is probably shaded most of the time, and its temperature must be 

 considerably lower than the average of the surrounding country.

 I collected this species in a sandy cornfield in the southeastern 

 part of Sumter county, about two miles from the Flint River, Sep- 

 tember 10 (no. 622), and in similar situations in Douglas, Sep- 

 tember 22 (no. 691). It has been known hitherto only from the 

 original station, Eustis, Fla., where Mr. Nash discovered it in 

 J 894. It is a common weed in Douglas, and has long been 

 known to the inhabitants there by the name of " water-grass." On 

 asking the origin of this curious name I was told that it is derived 

 from the fact that the plant is especially abundant after a wet 



summer.
