Some Notes on Juncus 
By K. M, WIEGAND 
Since the publiction of a previous paper on Juncus cenuds and its 
allies in the Buttetin for October, 1900, a large amount of addi- 
tional material has been studied, making some slight changes neces- 
sary in the treatment of the group. 
The range of /. dichotomus is extended westward along the Gulf 
coast to Texas. Alabama (Chas. Mohr); Mississippi (S. 4. 7; racy); 
Texas (Nealley, Thurlow, Wurzlow). 
At the time of the previous publication /. secundus seemed con- 
fined to the Atlantic coastal plain, and /. interior to the Ohio and 
Mississippi Valleys and the Great Plains. Two specimens from 
the Mississippi Valley have appeared, however, which can in no 
way be distinguished from /. secundus, and not without consider- 
able hesitation I am compelled to admit the occurrence of this 
species west of the Alleghanies. The specimens are : Missouri . 
(Desoto, H. £. Hasse, 1887), Ilinois (Vasey in Nat. Herb.). A 
plant from Lookout Mt. (Eggert) seems also to belong to this 
species. 
The range of /. occulentalis | is extended northward to Vancouver 
Island. 
Specimens of /. confusus have now been studied from the fol- 
lowing states and provinces: Alberta, Assiniboia, Washington 
(Spokane), Oregon (Warner Range), Idaho, Montana, Wyoming, 
Colorado. 
J. Georgianus Coville has been found also in North Carolina 
on Dennis Mt. (Sma//). 
Juncus Dudleyi Wiegand extends at least as far northwestward 
as Washington (Pullman, £. R. Lake, no. 175). 
Juncus interior occurs in the following states and territories : 
Illinois, Kansas, Indian Territory, Colorado, Wyoming, New Mex- 
ico and Arizona. 
Juncus Arizonicus curtiflorus Wiegand appears not to be dis- 
tinct from /. zterior. The material at hand when the description was-
