CCCCLXXI.) 
Hab. In Lapponia, Norvegia, et Finlandia.—In palu- 
dibus subalpinis, Fries. In locis sphagnosis, Andersson. 
Radix stolonifera. Culmus l|-pedalis, acute triqueter, su¬ 
perne nudus, scaber. Folia plana, lineam lata, apice longe 
attenuata, culmo breviora. Bractea basi squamseformis, ssepe 
aristata, spicula infima longior. Spica 6-8 lin. longa, 11-2 
lin. lata. Spiculae parvse, alternse, suprema basi attenuata. 
infima 3 lin. remota. Perigynium 1^ lin. longum, T % lin. 
latum, subbifidum, sinu acuto, pallidum, nervis fuscioribus. 
Inter C. loliaceam et C. tenuifloram media, ab utraque ore 
subbifido distincta. 
A C. tenuiflora differt radice stolonifera; foliis latioribus; 
spiculis alternis, suprema basi attenuata; perigyniis snbbifidis 
(sinu acuto), marginibus superne magis asperulis, nervis te- 
nuibus, coloratis. 
Fries and Andersson say “perigyniis squama obtectisfl which is 
certainly not the case with specimens I have received from Fries, 
and in others from Sonder. It is a character more applicable to 
G. tenuiflora. Andersson contrasts it with G. tenuiflora and O. 
vitilis. I think it is more closely allied to O. loliacea, with which 
it agrees in foliage and inflorescence, but the nerves are more de¬ 
licate and less prominent. I have a specimen of C. loliacea from 
Fries, in which the apex of the perigynium is more acute than 
usual, and occasionally slightly rough; and I suspect that C. ma¬ 
cilenta may prove to be a variety of it. Both plants are compara¬ 
tively rare in our herbaria. I have not seen matured perigynia 
of G. macilenta.

I have not given all the references to this very common Euro¬ 
pean plant, which extends from Lapland throughout Europe, and 
in Asia. In North America I have only seen it from the neigh¬ 
bourhood of Boston, and the specimens figured are from that lo¬ 
cality, differing occasionally from the European ones by the elon¬ 
gation of the peduncles. The species in Europe varies much in 
size, often not more than three inches in dry woods and sandy 
places, and in marshes a foot and a half high.

I have only seen a young specimen of the plant from thePyrenees, 
and must refer to the observations of Gay upon it. I think, with 
the author of the El. Ross, (under C. pulicaris, p. 265), that it is 
not specifically distinct from the Madeira and Azores plant. I 
have a specimen of O', peregrina, Link, from the Berlin Garden, 
identical with these last.. Link quotes “ Wormslciold ad fluvium 
Zayre ” for his species, but Kunth says of it “ patria ignota .” 
G.pulicari , L., affmis. Differt perigyniis longe rostratis, nec 
subventricosis ; foliis explanatis, latioribus ; squamis obtusis; 
culmo altiore. 
The specimens figured are from Madeira.-
