071 the Genus Juncus of Liuncriis. 30f) 



very significant ; for which reason I have adopted it. I think there 

 can be httle doubt of the figures wliich I have quoted belongino' 

 to this species, though that in Eng. Bot. has the capsule badly re- 

 presented, and more like J. bottniciis of Wahlenburg. J. compressus 

 is to be distinguished from J. cccnosus, 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; %vhereas canosus 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 /. Ge- 

 rardi, v. 5. p. 308. 



9' Juncus ccenosus. 

 Juncus culmo simplici folioso, foliis setaceis canaliculatis, cap- 



sulis obovatis obtusis longitudine calycis, panicul4 terminali 



subsimplici bractei longiore. 

 Angl. Mud Rush. 

 Habitat in salsis copiosfe. 

 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. Cahjx-leajiets 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 altosether darker colour of the
