106 HEXAMD. MONOG. 



Whole plant very v\gk\, G inches to afoot high. Leaves Hwh-recvrved, 

 about halt" as long as the scape. Bracteas lanceolate, membrana- 

 ceous. Leaflets of the perianth ovato-lanceolate, sliining broAvn, 

 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 acuminato-aristate. PVilld.

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 flower.s) , and by the acu- 

 minato-aristate ^jf/w/;^/;. It is a very distinct species, and well 

 figured in Sturm's excellent little Flora of Germany. 



8. J. triglnmis [three -Jlowered Rush), leaves linear-subulate 

 compressed, heads terminal erect of about 3 flowers sessile 

 longer than the membranaceous involucre, leaflets of the pe^ 

 riauth obtuse longer than the elliptical capsule. Light/, p. 1 86.

Hab. Highland mountains, very common, especially the m.ore ele- 

 vated, in bpggv places. Ft. July, Aug. 7/ . 



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

 stem, but truly radical. Involucres two, broadly ova^e, patent, deep 

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



9. J. biglumis {two-pnvered 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.
