same sheet. I passed the plant over in my Preliminary List of 
North American Species of Cyperus, (BULLETIN, xiii. 205-216), 
having only the original specimen to go by, and accepting Dr. 
Torrey’s later view. But recently I have had numerous speci- 
mens from the Northwest and other regions, which maintain the 
characters of the original, and satisfactorily establish the species 
as a good one. 
My attention has been especially called to it by Mr. John M. 
Holzinger, Assistant Botanist to the U. S. Department of Agri- 
culture, who last year sent me abundant specimens collected by 
Dr. E. A. Mearns, U.S. A., at Camp Douglas, Wisconsin. I 
did not then recognize in these Torrey’s species, and was disposed 
to regard the plant as undescribed. Mr. Holzinger has again 
sent me more and very fine specimens of Dr. Mearns’ collection 
of 1891, and thus by impressing on me the characters of the plant, 
caused me to make a careful examination of the group to which 
it belongs. 
The species is nearest C. Schwenits 22, but readily distinguish- 
able from that plant by its globose, dense heads, smooth culms, 
shorter and broader truncate or apiculate scales, and shorter 
nut. I have it now from the following localities: Lake of the 
Isles, N. W, Terr., (Houghton No. 73); Camp Douglass, Wisc., 
(Mearns No. 28); St. Croix River, Minn., (Holzinger); Cheboy- 
gan Co., Mich., (C. F. Wheeler); Wichita, Kans., (Carleton); 
Columbia River, Sand Island, Oregon, (Thos. Howell); Kuskuski 
River, (Wilkes Exp.); Wareham, Mass., (Ex. Herb. L. H. 
Bailey); Lake George, N. Y., (Wm. H. Leggett). It thus ranges 
all across the continent. I referred the Oregon specimens col- 
lected by Geyer, which I saw in Herb. Gray to this species in 
my Preliminary List, but was uncertain about them. They 
probably belong here. 
The plant which I described in my “Reem List (p. 208) 
as C. Schweinitsii, var. debilis, which extends from Colorado 
(Redfield) to Chihuahua, is most likely another distinct species. 
Rynchospora scutellata, Griesb. Cat. Pl. Cub. 246 (1866). 
This species, founded on Charles Wright’s No. 3406 from 
Western Cuba, was collected by the late Mr. H. W. Ravenel on 
damp prairies near Indianola, Texas, May 3d, 1869, (No. 160),
