" Capsule not at all angular, but rounded-elliptical with a furrowed 

 beak." W.Wilson. 



14. J. compressus, Jacq. (ground- fruited Rush); stem erect com- 

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

 pound subcymose generally shorter than the bracteas, capsules 

 roundish ovate longer than the obtuse incurved leaflets of the 

 perianth. Bich. in Tr. of Linn. Sac. v. xii. p. 307. — /3. panicle 

 nearly simple few-flowered longer than the bracteas. Hook. 

 Scot. I. p. 107 — J. Bothnicus, IVahl. — J. ccenosits, Bich. in Linn.

Wet marsh}- places, common. — /S. In salt marshes. Fl. Aug. If. — 

 Having now seen various specimens both of the J. ccenosus of ]Mr 

 Bicheno and J. Bothnicus of Wahlenberg, I feel confirmed in my 

 opinion expressed in FL Scotica, that they are but varieties of J. 

 cotnpi-essus. 



15. J. tenuis, Willd. (slender spreading Rush); stem above 

 shortly dichotomous panicled, leaves linear-setaceous grooved, 

 flowers solitary approximate mostly sessile, capsules nearly sphse- 

 rical shorter than the very acuminated leaflets of the perianth.

Moist mountains of Clova, D. Bon. Fl. July. If. — This rare British 

 plant seems abundant in America, and I possess specimens likewise from 

 various parts of Euroj)e. It is allied to J. bufonius, yet really distinct. 

 Radical leaves several ; stem bare of leaves np to the division near the 

 top, where is one leaf immediately beneath the foliaceous bracteas. In 

 the axils of the forks are 2 or 3 large, nearly sqssWq Jiowers, and 2 or 3 

 unilateral ones on the branches. The capsule is very different from 

 that of the following species. 



16. J. bufonius, L. (Toad Rush); stem dichotomous above 

 panicled, leaves filiform setaceous grooved, flowers solitary uni- 

 lateral mostly sessile, capsules elliptical ovate much shorter than 

 the very acuminated leaflets of the perianth. E. Bot. t. 802. 



Frequent in moist, or watery places, especially such as have been 

 overflowed in winter. Fl. Aug. 0. — 4 — 6 inches high. Leaves few, 

 slender, only one on the stem, generally near the middle. The divi- 

 sions, or ramifications of the stem, as they are called, belong more pro- 

 perly, I think, to the panicle, at the base of which are foliaceous brac- 

 teas. Whole plant very pale-coloured. Flowers green, with white mem- 

 branous margins to the leaflets oi the perianth.

17. J. squarrosiis, L. (Heath Rush); leaves setaceous (rigid) 

 grooved, panicle terminal elongated compound, capsules ellipti- 

 cal ovate. E. Bot. t. 933. 



Moory and heathy ground, abundant. Fl. June, July. If. — Whole 

 plant exceedingly rigid, 6 inches to a foot high. Leaves subsecund, 

 about half as long as the scape. Bracteas lanceolate, membranaceous. 

 Leaflets of the perianth ovato-lanceolate, glossy brown with a pale line 

 down the middle, scariose at the edges. Capsule, as in almost all this 

 genus, tipped with a short mucro, the remains of the style, palish-browu-
