 Carex ivakaiipu, n. sp. 



A C£espitose small species, much branched at the base. 



Leaves usually broad, flat, much longer than the culms, slightly scabrid 

 at the margins. Culms much shorter than the leaves, 3-angled, smooth, 

 invested by the sheathing bases of the leaves. Spikelets 4-6, erect, lower 

 shortly peduncled, upper sessile; uppermost male, others male at the top 

 only. Bracts long and leaf-like. Glumes ovate-oblong, brownish, mem- 

 braneous, bifid, with a rather long hispid awn, being a continuation of the 

 strong green nerve. Utricles turgid, biconvex, nerved, shortly bifid at the 

 smooth apex but scarcely produced into a beak. Stigmas 2. 



Hab. — Ben Lomond, near Queenstown, 3-5,000 feet. 



I have a good series of depauperized forms in some of which the spike- 

 lets are reduced in number, and conspicuously in length and stoutness. 



Carex goyeni, n. sp. 



A tufted strong-growing, dark-green, species. Culms stout, 3-angled, 

 almost smooth, a foot high or less. 



Leaves longer than the culms, flat, broad, keeled, scabrid at the margins. 

 Bracts long, leafy, flat. Spikelets 7 to 9, stout, cylindric, erect, 1 inch 

 long or less ; the lower somewhat distant, peduncled ; upper sessile, approxi- 

 mate ; uppermost male in the lower half, female above, others female with 

 a few male flowers at the bottom of the lower spikelets. Glumes nearly as 

 long as the utricles, rounded-ovate, membraneous, brown, shortly awned. 

 Utricles turgid, divaricating, pale, shining, nerveless, with a short bifid 

 beak which is smooth or slightly scabrid at the margins. Styles 2, short. 



Hah. — Head of Lake Wakatipu, 1,100 feet. 



This species is easily distinguished by its robust habit, its broad flat 

 leaves exceeding the culms, its short spikelets, and the absence of any 

 entirely male spikelet. It is named in honour of Mr. P. Goyen, who has 

 been for some time engaged in work calculated to throw considerable light 

 on the alpine flora of the S.W. of Otago.

 Carex longiculviis, n. sp. 

 A tall casspitose species, somewhat similar to Carex trijida, Cavanilles, 

 but more slender lax and tall. 



Leaves shorter than the culms, pale green, -i of an inch broad, usually 

 flat, keeled, smooth save at the margins near the top, the lower part with 

 an expanded sheath ending in a truncated ligule. Culms tall, rounded, 2- 

 3^ feet high. Bracts long, leaf-like. Spikelets 5 or 6, erect, stout; one 

 and sometimes two uppermost male only ; others with a few ruale flowers at
