Art. XLIV.—Description of two new Species of Carex.
[Read before the Otago Institute, 30th January, 1883.]
Carex littoralis, n. sp.
A Smooth, tufted species, 1 to 2 feet high. Leaves nearly as long as the culms, sheathing towards the base, very narrow, striate, plano-convex in section, almost smooth, pale green.
Culms round, smooth, with long leaf-like bracts shortly sheathing at the base.
Spikelets 4 or 5, uppermost slender, longer, male; lower female with a few male flowers below, stout, ¼ to ½ inch long, sessile or very shortly peduncled, the peduncle being enclosed by the sheathing base of the bract.
Glumes ovate, membranous, dark brown, with lighter three-ribbed midrib, produced into a short tapering awn.
Utricle ovate, turgid, two-ribbed, reddish-brown; beak short, bifid.
Arms of style 3 short.
Hab. Paterson's Inlet, Stewart Island; Otago Harbour. It appears to be confined to tidal swamps, and low-lying ground about the level of high-water mark. I have never seen it inland or in any other situations than such as are indicated above. Mr. Cheeseman, of the Auckland Museum, informs me that he has this plant from various parts of New Zealand, so that it evidently has a wide distribution.
Carex cheesemanii, n. sp.
A very slender, densely tufted, pale, rather harsh species.
Culms 16 inches, or less, rounded, very slender, drooping, elongating greatly during ripening.
Leaves very numerous, shorter than the culms, very narrow, flattened or plano-convex, scabrid, broad at the bases which sheath the lower parts of the culm.
Spikelets usually 6–8, lower distant on slender peduncles, upper approximate and nearly sessile; all short and pale-brown; uppermost male, others male at the base only; bracts very long and slender.
Glumes shorter than the utricles, broad, very membranous, pale-brown at sides, white near the three-nerved midrib which is continued beyond the bifid apex into a long usually scabrid awn.
Utricle turgid, plano-convex, pale-brown, beak short, bifid, toothed or plain.
Arms of the style 3.
Hab. Maniototo Plain 1,000–2,000 feet; Nevis Valley 1,500 feet.
Named in honour of T. F. Cheeseman, Esq., Curator of the Auckland Museum, who has done much to settle the New Zealand species of this genus.
