Peren. July, August. 
Root creeping, black.. Stem from one to two feet high, striated,

inċurved summit; sheathed at the base with large, brown, 
shining scales. Panicle lateral, bursting about one-third the

lyx-leaflets striated, very acuminate ; three inner leaflets shorter.

However easily distinguished this plant may be on’ examination, - 
it is uncertain whether it was known to Linnæus, although a pro- 
duction of Sweden, or he has included it in his J. inflexus, which 
no botanist since his time has understood. Willdenow has suf- 
fered the latter species to remain in his edition of the Species 
Plantarum, and adds from his own observation this remark: 
** Culmi suprema pars non est teres, sed folii ad instar compres- 
sus*." Sibthorp, who seems to have taken the J. glaucus up 
from Ehrhart (Gram. 85.), first introduced the trivial name into 
the British Flora, It may be known even at a distance from the 
soft Rushes, by its rigid stem, of a glaucous hue, and scanty pa- 
nicle; and, on a closer view, by its pointed capsule. Wahlen- 
burg (Flor. Lapp. p. 79.) says of those specimens he found in 
Lapland, that the flowers were larger than those figured in En- 
glish Botany. 
* The authors of the Flore Francaise; vol. v. have expressed their opinion that the 
J. inflexus of their third volume is nothing more than J, glaucus; adding at the same time, 
that the real J, inflexus, Linn, has but three stamina,
