 setaceous rigid grooved, panicle terminal elongated compound, 

 capsules elliptical-ovate very obtuse about as long as or scarcely-

E. Med. — In moist pastures immediately below the Wilderness, 1844. On 

 several parts of Bleak down, abundantly. Pastures about Rookley farm.

Plant extremely rigid, smooth and shining, growing for the most part in round 

 tufts, and conspicuous from the bright green of its short, very stiff and narrow 

 leaves. Root densely tufted and creeping with stout, short, and in my specimens 

 mostly downy fibres. Stems erect, from about 6 — 12 inches, rounded or some- 

 times much compressed, furrowed or obscurely angular, not jointed, invested at 

 the base with one or two leaves with close sheaths, which however, like the rest, 

 are really from the root-crown ; there is, however, though rarely, a true cauline 

 leaf about the middle of the stem. Leaves almost entirely radical, singularly stiff 

 and wiry, fascicled and forming dense, circular, radiating tufts, usually about half 

 as long as the stem, spreading or partly erect, more or less recurved, bright green, 

 linear, semiterete or rather deeply depresso-caniculate, acute, with blackish tips 

 and reddish white, striated and shining bases. Panicle terminal, elongated, but 

 litlle compounded, of two principal, erect, very unequal branches, with a common 

 sheathing, reddish brown, taper-pointed, often leafi/ bract at their base, besides an 

 inner obtuse or bifid and smaller one opposite to and concealed by the former ; the 

 branch continued directly from the stem, usually much longer than the oblique or 

 lateral and more compounded one, the bracteal arrangement repeated at each 

 bifurcation, but the upper bracts are similar lo the floral, and without leafy points. 

 Floivers rather large, appearing clustered, with a pair of close ovate scariose bracts 

 under each, and a third immediately below these at the origin of the very short 

 pedicels. Segments of the perianth nearly equal, lanceolate, not very acute, con- 

 cave, dark livid brown, with broad, grayish, membranous edges. Stamens much 

 shorter than the perianth. Capsule about 2 lines in length, pale brownish or 

 grayish, smooth and shining, scarcely quite equalling the calyx, ovoid-elliptical, 

 very obtuse, tipped with the base of the style. Seeds very small and numerous, 

 dark brown, of an irregular prismatic shape, oblong or subreniform, rounded or 

 somewhat angular and pointed at one end, gibbous at the back, closely and finely 

 punctato-striate, covered apparently, when viewed under a high magnifier, with a 

 thick transparent pellicle. 



*»*** Stems leafy. Leaves plane or grooved above, not distinctly jointed. 



11. J. compressus, Jacq. Round-fruited Rush. "Stem erect 

 more or less compressed, leaves linear- setaceous grooved, panicle 

 terminal compound subcymose, capsules roundish-ovate or oval 

 mucronate equal to or longer than the oval-oblong obtuse incurved 

 sepals." — Br. Fl.

 ovate shortly mucronate capsule." — Br. Fl. J. bulbosus, F. B. t.9M. Host.
