JUNCUS MONOSTICHUS IN OHIO. 
ALMON N. Roop. 
On Oct. 13th, 1912, while walking across a large pasture field I 
noticed a strange and, to me, new species of Juncus growing among 
the somewhat brown and half dried grasses and sedges. A hasty 
collection of several specimens was made and upon returning home a 
more careful examination convinced me that the plant was Juncus 
monostichus Bartlett. An examination of records showed that if it 
was indeed this species my find was east of any reported range so, in 
order to check any possible error, specimens were sent to Prof. 
Robinson of the Gray Herbarium and to Prof. Schaffner of the Ohio 
State University, both of whom confirmed my identification. 
This plant has not, so far as I can learn, been reported from Ohio. 
It appears distinct from any Juncus with. which I am acquainted and 
the plants would at once attract the attention of a botanist because 
of the peculiar arrangement of the flowers which are erect in a single 
row on the upper side of the branches of inflorescence. These branches 
at this time had curled inward at the tips, presenting an almost scor- 
pioid appearance. 
This latter characteristic would probably not be evident earlier 
in the season but a dry summer and several severe frosts had partially 
turned their color from green to brown and caused the tips of the 
branches to roll inward. 
Though several plants were found in this one spot I did not search 
the surrounding region to see if it was at all prevalent elsewhere but 
think the find is rare for this locality. There was nothing to indicate 
that the plant had been introduced as the station was in a large, 
natural pasture which had never been plowed and not near any evi- 
dent source of plant introduction. 
Growing with it were an abundance of typical Juncus tenuis Willd. 
and occasional plants of a form of Juncus marginatus Rostk. Next 
season I shall try and make a more thorough examination of the 
locality with respect to this species.
