broad. Achenium oblong, triquetrous, shorter than the flat linear serrate racheola, which is green, ferruginous at the 
tip.—Allied to C. caduca, Boott, of Fuegia, which differs in having two stigmas, compressed perigynia, a lenticular 
achenium, and shorter lower scales. —PLATE LXIII. C. Fig. 1, spike with the lower scale removed; 2, perigy-

Has. Northern Islands; Ruahine mountains, and marshes on the East Coast, Colenso. 
A very slender species, with smooth filiform culms 6-9 inches long, and very narrow leaves. Bracts unequal, 
the lowest often 2-4 inches long. Spikelets one to three, crowded, pale, broadly ovate.— This is also a native of 
Australia and of Tasmania.

Has. Northern Island; dry grassy plains in the interior, Colenso. 
Similar to C. inversa, but a more wiry plant, with larger, more coriaceous, brown spikelets, and shining chesnut 
oval perigynia, that have no beak, and indistinct nerves. Culms 3-9 inches long, angles obtuse, often flexuose, 
smooth or rough above. Leaves involute, shorter than the culm, wiry. Bracts one or two, the lower nearly 1 inch 
long. Spikelets turgid, 3-4 lines long, 13-2 broad. —PLATE LXIII. B. Fig. 1, spikelet; 2, perigynium ; 3, ache-

5. Carex stellulata, Good.; spiculis 3-4 androgynis basi masculis paucifloris alternis nudis suprema

ovata acuta longioribus, stigmatibus 2. Boott, MSS. Engl. Bot. t. 806. 
Has. Northern Island; in bogs at Lake Taupo, Colenso. (Native of England.) 
A very common British plant, a native of boggy places throughout temperate Europe, Asia, and North America. 
Culms a span to a foot high, very slender, with short brown spikelets, forming an interrupted ovate spike 4-1 inch 
long, which appears squarrose from the spreading perigynia. Spikelets few-flowered, without bracts. 
** Spikelets with male flowers at the top. 
6. Carex teretiuscula, Good.; spica oblonga subpollicari nuda v. bracteata e spiculis androgynis 
apice masculis paucis ovatis sessilibus contiguis composita, perigyniis ovatis conico-rostratis bidentatis su- 
perne alatis serratis plano-convexis dorso nervatis squamam acutam subzequantibus, stigmatibus 2. Boott, 
MSS. Engl. Bot. t. 1065. 
Has. Northern Island; in bogs at Hawke’s Bay, Colenso. (Native of England.) 
This, like C. stellulata, is also a common plant of the north temperate zone, but has only been found in New 
Zealand in the southern hemisphere. Culms very slender, a span to 2 feet high, bearing a terminal, rather dense, 
linear oblong spike, of a few crowded spikelets, whose perigynia spread as in C. stellulata. 
7. Carex secta, Boott; spica androgyna apice mascula elongata seepe subsesquipedali decomposita
