80 TRANSACTIONS OF THE [fEB. 22, 



24. Scirpiis inaritinius, L. 



So'rpiif! maritimus, L. Sp. PL, 51 (1753). 



In swamps. Manitoba to Ne])ra8ka, Texas, and Mexico; west 

 to the Pacific Coast. Also in Europe, Asia, Africa, and Anstralia. 



The plant of the northwest coa.st, as illustrated by the specimens 

 from Puget Sound (Wilkes's Exp.), Umpqua River (Howell), and 

 Vancouver Island (Macouu), appears to be identical with the Euro- 

 pean, but I have seen no ripe fruit of it. Many of those from the 

 interior of the continent, such as Watson's 1214, from Humboldt 

 Sink, JS'evada; Wright's 19G2 and 1942, from New Mexico; and 

 others ranging from Nebraska to Sonora, differ in having very light- 

 colored glumes, and have a compressed nut, much like that of the 

 following species. These may form a distinct species. The Euro- 

 pean specimens which I have examined have a trigonous nut.
