106 MEXAND. MONOG. 



Whole plant very rigid, G inches to a foot high. .Le^fcs sub-rconrved, 

 about half as long as the scape. Bractcas lanceolate, membrana- 

 ceous. Leaflets of the perianth ovato-lanceolate, shining brown, 

 with a pale line down the middle, and scariose at the edges. Cap- 

 sule, as in almost all the genus, tipped with a short mucro, the re- 

 mains of the style ; palish brown. 



7. J. cap' 'talus (capitate Rush), leaves filiform (soft.) plane or 

 grooved above, heads of flowers sessile terminal shorter than the 

 bractea, leaflets of the perianth acurninato-aristate. Wiltd.

HAB. The highest parts of Ben Lawers, G. Don. It does not appear, 

 however, on the continent, to be at all an alpine species. 



Whole plant only from 2 4 inches high, flaccid. Leaves entirely ra- 

 dical, about half its length, erect. Heads rather large, of from 3 6 

 flowers, sessile, occasionally proliferous, admirably distinguished by 

 the setaceous inclined bractea, with its sheathing membranaceous 

 base (which is larger than the heads of flowers), and by the acu- 

 minato-aristate perianth. It is a very distinct species, and well 

 figured in Sturm's excellent little Flora of Germany. 



8. J. triglumis (three -flowered Rtish), leaves linear-subulate 

 compressed, heads terminal erect of about 3 flowers sessile 

 longer than the membranaceous involucre, leaflets of the pe- 

 rianth obtuse longer than the elliptical capsule. Lightf. p. 1 86.

HAB. Highland movmtains, very common, especially the more ele- 

 vated, in boggy places. Fl. July, Aug. 1J.. 



Four to six inches high. Leaves short, with sheathing bases around the 

 stem, but .truly radical. Involucres two, broadly ovate, patent, deep 

 brown, as well as the leaflets of the perianth, with paler edges. 



9. J. bightmis (two-^flowered Rush), leaves linear-subulate com- 

 pressed, heads terminal a little leaning of 2 flowers one of them 

 pedicellate shorter than the foliaceous involucre, leaves of the 

 perianth obtuse longer than the turbinate emarginate capsule.

Generally smaller than the last ; most distinct in the brae teas and
