6. C. elongata, Linn. Elongated Carex. Spikelets numerous, oblong, lax, rather distant, sterile at the base, lowermost bracteated; fruit patent; glumes rotundo-ovate, obtuse, shorter than the fruit; perigynium sessile, oblongo-acuminate, plano-convex, strongly ribbed, margins rough, orifice scarcely bifid; nut linear-oblong, tapering at the base, compressed, obsoletely subtriquetrous, smooth. E. Bot. t. 1920. E. Fl. v. iv. p. 82. Hook. Br. Fl. 4th ed.

Fl. June. 2.

p. 332. Marshy margins of lakes; rare. Colemere mere, below the point where the Ellesmere Canal leaves the direction of the mere; J. E. Bowman, Esq!

Root tufted, with long stout fibres. Stem 18 inches to 2 feet high, triangular, rough above. Leaves verry narrow, linear, acute, striated, rough at the edges and keel below the point. Spikelets 9-10 or more, rusty brown, oblong, narrow, scarcely tumid, crowded above, lax and distant below, the lowermost subtended by a bractea more or less leafy. Glumes rotundo-ovate, more or less obtuse, dark brown with a green keel and whitish membranous edges. Perigynium 7-ribbed on convex side, about 5-ribbed on plane one.

7. C. remota, Linn. Distant-spiked Carex. Spikelets several, small, sessile, sterile at the base, 3 lowermost very distant, subtended by very long leafy bracteas, the lowermost reaching beyond the spike, uppermost spikelets crowded, inconspicuously bracteated; fruit erect; glumes oblong, acute, single-nerved, rather shorter than the fruit; perigynium oblongo-ovate, shortly acuminate, attenuate at the base, plano-convex, ribbed, margins rough, orifice bifid; nut elliptical, compressed, very minutely elevato-punctate. E. Bot. t. 832. E. Fl. v. iv. p. 84. Hook. Br. Fl. 4th ed. p. 332. Moist shady places; not common. Fl. June. 4.

Canal between Shrewsbury and Uffington. Lane leading from Longden to Oaks Hall, near Pontesbury. Morda pool, near Oswestry.

Root tufted, fibrous. Stem 1-2 feet high, slender, smooth and roundish below, triangular and rough above. Leaves very narrow, linear, acute, edges incurved, rough. Spikes flexuose or zigzag. Spikelets numerous, ovate, pale, sessile, 3 lower ones remote, each subtended by a very long narrow leafy bristle-pointed bractea, that of the lowermost spikelet extending beyond the extremity of the stem; upper spikelets small, more or less crowded, with small inconspicuous not leafy bracteas. Glumes broadly oblong, acute, membranous and whitish, the single pellucid nerve terminating below the apex and with a stripe of green on each side, rather shorter than the fruit. Perigynium obscurely 5-ribbed at the base on the plane side; the convex side with a cordlike mass of ribs which proceed downwards from the bifid orifice to a little above the middle, where it diverges into five ribs, which again converge and unite a little above the base.

C. axillaris seems to be chiefly distinguished from remota by the lowermost spikelet being compound and subtended by a long leafy bractea extending beyond the spike, the bracteas of the other spikelets being shorter; whilst in remota the bracteas of the 3 lowermost spikelets which are simple all extend beyond the spike. The character from the number of nerves of the glumes seems variable. In axillaris the perigynium is elliptical, attenuated at both ends, with similar ribbing to that of remota. The form of the nut in both is nearly alike.

tt Spikelets alternate, sterile at their extremity.

8. C. intermedia, Gooden. Soft brown Carex. "Inferior and terminal spikelets fertile, all crowded into an oblong interrupted head, the intermediate ones sterile; fruit acutely margined, longer the glumes; bracteas membranaceous, the lower ones somewhat leafy; stem triangular, leaves plane." Hook. Br. Fl. 4th ed. p. 333. E. Bot. t. 2042. E. Fl. v. iv. p. 86.

Wet meadows; rare. Fl. June. 4.

Meadows under Cronkhill. On the banks of the river Tern. Between Halston and Hardwick; Rev. E. Williams's MSS.

Root deeply creeping. Stems 1-1 foot high, erect, with 3 rough unequal angles. Leaves chiefly in the lower part of the stem, sheathing, scarcely reaching to its summit. Spike oblong, bluntish, of a rusty brown, moderately compressed, lowermost one subtended by an ovate bractea terminating upwards in a setaceous leaflet, the rest with an ovate leafless bractea. Fruit large, not so distinctly winged as gradually flattened towards the margin, beak serrulate upwards, deeply bifid, striated. In all the specimens which I have ever seen of this species the nut has been invariably abortive.

9. C. muricata, Linn. Greater prickly Carex. Spike oblong, dense or interrupted at the base, spikelets compact or approximate; fruit spreading; glumes ovate, submucronate; perigynium tapering at the base or substipitate, ovato-acuminate, plano-convex; margins rough, orifice bifid; nut broadly oblong, plano-convex, minutely granulated.

Hedge-banks near Lower Berwick on the turnpike road-side. Near Berrington. Lane leading from Longden to the Oaks Hall, near Pontesbury. Hedgebanks between Shrewsbury New Race Course and Monkmoor.

Root tufted, fibrous. Herbage of a bright grass-green. Stem erect, 1-2 feet high, slender, triangular, smooth, striated and roughish above. Leaves chiefly in the lower portion of the stem, narrow, linear, acute, rough at the edges and keel. Spikelets 8-10, of a rusty green, upper ones dense, I or 2 of the lower ones only slightly remote. Bractea of the lowest spikelet small setaceous dilated and membranous at the base, those of the upper ones broadly ovate membranous with a long rough mucro, somewhat similar to the glumes. Glumes membranous, single-nerved. Fruit yellow-brown.

In specimens from Llandidno, North Wales, (communicated by Mr. W. Wilson) and from the Pentland Hills, Scotland (sent by Rev. T. B. Bell) the spikelets are approximate and only 6 in number, the perigynium much larger and full one-fourth longer, the beak being much more elongated and acuminated, and the nut broadly ovate obtuse compressed subplano-convex. In size and all other characters they apparently correspond with our Shropshire muricata. Of the Llandidno plant Mr. Wilson remarks: "rather different from any elsewhere seen." The size of the perigynium and form of the nut of the Llandidno specimen are identical with those parts in Vignea muricata. No. 409. Reich. Fl. Germ. Exsicc.! Do not these differences indicate the probability of two distinct species being comprehended in that usually named muricata?
