166 HEXANDRIA— MONOGYNIA. Juncus. 



rected. Nor have I any doubt of the propriety of distinguishing 

 the following, though they have been confounded by Linnaeus in 

 his herbarium, by Dickson in his H.Sicc.fasc. 13. 14, by Haller, 

 in their synonyms at least, and hitherto perhaps by all botanists. 

 Gmelin's figure, Fl. Sib. t. 17. f. 2, cited by Wahlenberg for his 

 bottniciis, is so very bad as to be unintelligible, nor can I quite 

 satisfy myself respecting this last-mentioned species, by a single 

 Nuremberg specimen from Dr. Panzer, which is all 1 have seen. 

 The very suitable name of compressus is authorized by an early 

 work of Jacquin, his Enumeratio, or Catalogue of the plants 

 about Vienna, published in 1762, with observations upon the 

 rarer species at the end. Willdenow has misled Mr. Bicheno 

 to quote this publication by another title, Jacq. Obs., under 

 J. trijidus, which may cause a mistake, Jacquin's Observationes 

 being a very different and more common book.

Stem simple, leafy. Leaves linear, channelled. Panicle 

 cymose, terminal, longer than the bractea. Capsule ob- 

 ovate, the length of the rather obtuse calyx.

In salt marshes, and muddy places towards the sea, abundantly. 



Differs from the last in the darker colour of the whole plant, but 

 especially of the Jlowers and capsule. The stem is more leafy, 

 and in the upper part rather triangular than compressed. Leaves 

 more rigid, and externally striated. Panicle less compound, not 

 overtopped by the bractea, but often rising considerably above 

 it. Pair of bracteas under each flower of a shining brown, not 

 white or greenish. Calyx-leaves all oblong, and nearly equal in 

 breadth, as well as in length, with an obtuse, concave, or in- 

 curved point, all of a chocolate brown, with a broad, tumid, 

 green, striated, 3-ribbed keel, and closing round the capsule, 

 which hardly ever extends beyond them, and is brown, obovate, 

 triangular, bluntish with a small point, altogether less tumid 

 than the foregoing. 



Mr. E. Forster found a dwarf variety of J. coenosus, about 3 inches 

 high, on the coast of Glamorganshire. 



The appropriation of the synonyms of these two species is a matter 

 of great difficulty, and after having studied the original authors 

 with some care, I must submit them to the correction of future 

 critics. All my Swiss specimens, from various quarters, consi-
