This northern jilant with short spikelets and firm green scales 

 seems in its extreme form very distinct from the typical Cyperus fili- 

 culmis of the South, but some specimens occur with few flowers but 

 yellow-tinged thinnish scales, others with numerous flowers and firm 

 scales. 



Eleocharis capitata (L.) R. Br., var. dispar (E. J. Hill), n. 

 comb. E. dispar, E. J. Hill, Bot. Gaz. vii. 3 (1882). 



This local plant of Lake County, Indiana, has of late been treated 

 as identical with the tropical and subtropical E. capitata, Avhich occurs 

 along the Gulf of Mexico and in Florida and extends northward along 

 the coastal plain to Maryland. In its essential characters the material 

 from northern Indiana cannot be separated from the southern plant; 

 but E. capitata has whitish-brown scales and jet-black achenes, while 

 E. dispar has the scales purple-brown and the achenes purple-black. 

 These color characters hold in the twelve Indiana specimens before me 

 and on this account the plant seems worthy recognition as an extreme 

 extralimital variation from the tropical and subtropical type. 



Eleocharis nitida, n. sp. Perennial from a slender rootstock: 

 culms capillary, 4-angled, striate, 2 to 8 cm. high: tips of the upper 

 sheaths whitish: spikelet oblong-ovoid, acutish, 2.5 to 4.5 mm. long, 

 1.5 to 2.5 mm. thick, 8 2()-flowered: scales elliptic-oblong, with 

 rounded tips, ])urplish-brown, with greenish ribs and very narrow 

 scarious margins, the lowermost 1 to 1.2 mm. long: achenes whitish- 

 straw-color, narrowly olxnoid, sharply trigonous, very mniutely 

 (under a lens) roughened, 0.7 to 1 mm. long; the very narrow crown- 

 like tubercle with a short point in the middle. — Quebec, sj^ringy
