on the Genus Juncus of Linneus. 300 
very significant ; for which reason I have adopted it. I think there 
-can be little doubt of the figures which I have quoted belonging 
to this species, though that in Eng. Bot. has the capsule badly re- 
presented, and more like J. bottnicus of Wahlenburg. J. .compressus 
is to be distinguished from J. cenosus, the next species, by its 
lighter colour, broader and more concave leaves, the capsule be- 
ing longer than the calyx, and the lower bracte longer than the 
panicle. The leafy stem and blunt calyx-leaflets are sufficient 
marks to separate it from the rest of this subdivision. It is ge- 
nerally an inland plant; whereas cenosus is confined to the shore. 
The authors of the Flore Francaise seem to have observed the dif- 
ference of the two plants, and have, I conceive, described the sea- 
shore species under their bulbosus, and the inland one under J. Ge- 
rardi, v. 5. p. 308. : :

Habitat in salsis copiosè. 
Peren. July, August. 
Root creeping, fibrous. Stem from two inches to a foot high, erect, 
leafy, simple, smooth. Leaves setaceous, channelled, slightly 
_ striated. Panicle inclined to a corymb, terminal, erect, few- 
flowered, longer than. the bracte. — Bracte at the. base of the pa- 
| : nicle setaceous.  Calya-leaftets obtuse, dark chocolate-coloured, 
as long as the capsule ; three inner leaflets scariose at the mar- 
gin. Capsules somewhat unilateral, obovate, very obtuse. , 
I rely principally on the shape of the capsule, the proportion 
it bears to the calyx, the more rigid nature of the stem and leaves, 
the length of the bracte, and the altogether darker colour of the
