THE GEOGRAPHIC RANGES OF CERTAIN JUNCI 
POIOPHYLLI. 
HARLEY Harris BARTLETT. 
Juncus VaskEvi Engelm. ‘The most recent statement of the range 
of this species (Gray's Manual, Ed. 7) is “northern New Brunswick 
to Saskatchewan, south to central Maine, northern New York, Michi- 
gan, Illinois, Iowa, and Colorado." ‘The two following stations 
“ 
extend this range well to the northward of Bourgeau's station “оп the 
Saskatchewan": — Keewatin; between Echimamash River and 
Oxford House, July, 1880, Robert Bell. (Upon this collection are 
based the records of Juncus tenuis Willd. in Report Geol. Surv. 
Canada, 1879-80, p. 65c and in Macoun, Catalogue of Canadian 
Plants, iv. p. 59). Athabasca; North of Peace River, 5 July, 1903, 
J. M. Macoun 61281 (distributed as Juncus Dudley Wiegand). 
Juncus Duprey Wiegand. ‘The range given for this species in the 
Manual, “Quebec to Saskatchewan and the Rocky Mountains," 
etc., should be extended to include Washington. Juncus Dudleyi was 
recorded from this state by Wiegand in Bull. Torr. Bot. Club, xxx. 
(1903) p. 446, but Piper did not include it in his Flora of Washington. 
I have seen the following specimens: — from various stations in 
Klickitat Co., Suksdorf 1043, 2523, 3232, 3273, 5052, 5053, 6224, & 
6225; Cape Horn, Skamania Co., 19 Aug. 1894, Suksdorf 3594; 
Latah Creek, Spokane Co., 28 June, 1889, Suksdorf 1043. 
JUNCUS INTERIOR Wiegand. Washington should be included in the 
range of this prairie type, on the basis of a specimen from Prosser, 
Yakima Co., Cotton 647 (distributed as Juncus tenuis and cited under 
this name in the Flora of Washington). 
JUNCUS BRACHYPHYLLUS Wiegand. This species is known from 
New Mexico (v. infra), the region of the upper Platte (western Ne- 
braska, northern Colorado, or Wyoming), Idaho, Oregon, and Wash- 
ington. ‘The extension of its range into the two latter states is based 
upon beautiful specimens received for determination from Mr. Suks- 
dorf, and upon other specimens which were unidentified or incorrectly 
identified when received at the Gray Herbarium. These are: — Ore- 
gon: Hood River Valley, Wasco Co., Suksdorf 210 & 215. Washing- 
ton: moist hillsides, Blue Mountains, Columbia Co., Horner
