The affinity of this species, among its European allies, is with 
C. prcecocc , Jacq., and with the Eastern C. breviculmis, Br., and 
C. Ckinensis, etc. Whether the O. depressa, Link and Schk., is 
referable to this species or not, we have no materials for a satis¬ 
factory opinion. The plant figured by Schk. is probably the 
same as that of Willdenow, which Kunth refers to C. alpestris, 
All. {Q. Halleriam, Asso). The specimen is young, with aristate 
male and female squamse, 2 radical spiculse apice masculse, and the 
culm without any lateral one. Link describes his plant as having 
superior axillary spiculse and one radical one, thus differing from 
the figure of Schk. and the description of Willdenow. Still it 
is more than probable that the plant, which they called by Link’s 
name, was from his collection, and at the time Kunth wrote there 
was no European species known beyond C. alpestris, to which it 
was likely to be referred. The aristate squamse and the andro¬ 
gynous radical spiculse lead me to believe that it is the same as 
the plant of Jordan. The specimens which my late friend Dr. 
Charles Lemann sent me in 1841, from Gibraltar, I had referred 
to C. clepressa, Link, but in the uncertainty about that plant I 
merely quote it as a doubtful synonym. The specimens figured 
are those of Durieu, from Algiers.

triquetrum, ovale, stipitatum, fuscum. Racheola squamsefor- 
mis, apice serrata, extra os perigynii protusa, rarius adest. 
I have not seen this species south of New York. It is not in¬ 
cluded in the ‘Flora Cestrica’ of Darlington, nor do Elliott or Chap¬ 
man notice it. I have only observed the racheola in the Arctic spe¬ 
cimens brought hy Sir John Richardson. Muhlenberg and Torrey 
say it has rarely 2 stigmas. I have not observed this variation.

I have not found this species in any of the later collections, and 
am indebted to Professor Tuckerman for the specimens figured, 
which he received from Kunze. It differs from Himalayan plants 
in all its spikes being androgynous, its nerved perigynium and 
filiform leaves.
