Arrt. XLIV,— Description of two new Species of Carex. By D. Perrm, M.A. 
[Read before the Otago Institute, 30th January, 1883.] 
: Carez littoralis, n, sp. 
A suoorH, tufted species, 1 to 9 feet high. Leaves nearly as long as the 
culms, sheathing towards the base, very narrow, striate, plano-convex in 
section, almost smooth, pale green, č 
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, 1 to i 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 mid- 
rib, produced into a short tapering awn. 
Utricle ovate, turgid, two-ribbed, reddish-brown ; beak short, bifid. 
Arms of style 8 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. i 
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.
