Hap. Ben Challum, Dr. Stuart {in Bich.). Near the summit of Ben 

 Lawers, Mr. Dickson awA Mr. J. Mackuy. Fion Glen, behind Craig 

 Calliach, Breadalbane, Mr. Borrer. — Always growing in micaceous 

 soil. Fl. July. 1/ . 



This interesting plant is, 1 believe, peculiar to Scotland, and, as far 

 as I know, to the places above mentioned. It is quite unlike any 

 other. Root throwing out runners. CidniS — 10 inches high, erect. 

 Leaves all butone radical, with sheathing membranous bases ; that 

 one is sometimes, but by no means generally, near the summit. 

 Heads of from 3 — 5 acute flowers, of a dark brown colour. Cap- 

 sules almost black. Mr. Bicheno describes the leaves as jointed at 

 the top ; my specimens do not appear so. Juncus Jacqu'ini, with 

 which this has been confounded by some, is totallv difi'erent, being- 

 more allied to /. ^r/^f/w.s-, quite destitute of leaves below, with never 

 more than one head, of remarkably acuminated flowers. The figure 

 in E. Bot., which my friend Mr. Bicheno finds fault v/ith, admirably 

 accords with my specimens of eastuneus, and cannot be assimilated 

 with J. Jacquini. 



11, J. trifidus {three- leaved Rush), sheaths fringed those at the 

 base of the culm leafless, bracteas foliaceous very long grooved, 

 heads of about 3 flowers terminal, culm unifoliate. Lightf. 

 p. 183. /. 9. E. B. t. HS2. Bicli. in Linn. Trans, v. 12. 

 p. 314. 



Hab. Highland mountains, abundant. Fl. July, Aug. 1/ . 



Very unlike any other British Juncus. Roots creeping. Lower sheaths 

 with, at most, a short awn, scarcely to be termed a leaf, and that only 

 in the superior of the radical sheaths. A solitary leaf on the stem 

 generally near the summit, 2 OT 3 inches long, linear-setaceous. 

 Bracteas 2 under each head of 1 or 3 flowers precisely similar to 

 the leaf just described. 



12. J. huibosus {roiind-fruiled Rnsh), culm simple leafy com- 

 pressed, leaves linear-setaceous grooved, panicle terminal com- 

 pound subcyuiose generally shorter than the bractea, capsules 

 rotundato-ovate longer than the obtuse incurved leaflets of the 

 perianth. Lightf. p. 184. E. B. t. 934. Bich. in Linn. Trans. 

 V. 12. p. 307 {J. compressus). 



^. coenosuSy panicle nearly simple few-flowered, longer than the 

 bractea. J. coenosus, Bich. hi Linn. Trans, v. 12. p. 309. 



Hab. Wet marshy pastures, common. /3. Salt marshes, common, 

 D.Don. Fl.Aug. H. 



Eight inches to a foot high. Leaves mostly radical, rather long. I have 

 the J. ccenosus^ from Mr. Bicheno himself, but I cannot find it to 

 differ at all in the capsule from J. bidljosus. Both are perhaps a 

 little narrower at the base than at the summit. 



^ At first I tuok this plant for the ./. IjothnicHs, and I am now by no means 

 sure that the Lapland plant is really distinct, though it has uarrnwcrcapiules.
