or fascicles, and densely crowded near the tips of the primary rays; glumes 
10-15 on each side, broadly lanceolate, acute; stigmas 3; nut iriquetrous. 
At once distinguished from C. ustulatus by its flaecid slender leaves and 
rounded heads. The spikelets are sessile, but assume a pedicellate appear- 
ance from the falling away of the lower glumes. 
North Island—Hutt Valley ; especially plentiful by the Waiwetu River.

Isolepis " globosa," J. Buchanan ; Trans. N.Z. Inst., IIL., p. 211. 
The spikelet varies greatly in size and form, from 3-3 of an inch in 
length, and from ovoid to linear; small states cannot be distinguished from 
ordinary I. prolifer, Br. ; for, although Mr. Buchanan gives the smooth nut 
as a differential character, I have never seen New Zealand specimens of 
I. prolifer with dotted nuts. I am uncertain as to the propriety of con- 
sidering one or two of the series of forms included under I. prolifer as 
distinct plants, or as varieties of one protean species—the present amongst

Allied to C. glomerata, Br., but distinguished by its drooping habit, open 
panicle, and small florets. 
North Island—Lakes in the Lower Waikato; Tikitapu Lake, Taupo. 
Gahnia rigida, Kirk; Trans. N.Z. Inst., IX., p. 551.

Gahnia hectori, Kirk ; Trans. N.Z. Inst., IX., p. 551. 
A very distinct species, allied to G. procera, Forst. 
North and South Islands—As far south as Okarita. 
Carex chlorantha, Brown; Prodromus, 242. ; 
A small rather stout species, culms 3-6 inches high, rigid; leaves 
shorter than the culms; spike compact, oblong, of 5-8 oval androgynous 
spikelets, bract short; male flowers below, crowded ; stamens 3; glumes 
ovate-acuminate, utricle pyriform, margins serrulate ; stigmas 2. 
North Island—Waitemata.
