24. Scirpus maritimus, L. 
Scirpus maritimus, L. Sp. Pl., 51 (1753). 
In swamps. Manitoba to Nebraska, Texas, and Mexico; west 
to the Pacific Coast. Also in Europe, Asia, Africa, and Australia. 
The plant of the northwest coast, as illustrated by the specimens 
from Puget Sound (Wilkes’s Exp.), Umpqua River (Howell), and 
Vancouver Island (Macoun), 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, Nevada; Wright’s 1962 and 1942, from New Mexico; and 
others ranging from Nebraska to Sonora, differ in havi ing very light- 
colored elumes, 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.
