or fascicles, and densely crowded near the tips of the primary rays ; glumes 

 10-15 on each side, hroadly lauceolate, acute ; stigmas 3 ; nut triquetrous. 



At once distinguished from C. ust.}(latns by its flaccid 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.

 North Island — Cape Colville. 



Isolepis "g'obosa/' J. Buchanan ; Trans. N.Z. Inst., III., p. 211. 



The spikelet varies greatly in size and form, from ^-| 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 

 /. 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 

 them. 



North Island — About Wellington. 



Isolepis fluitans, Br. ; Scirpusjinitans, L., Kirk, Trans. N.Z. Inst., III., p. 166.

 South Island— The Bluff Hill (a doubtful identification.) 



Cladium Irattoni, Kirk; Trans. N.Z. Inst., IX., p. 551. 



Allied to C. glomcrata, 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.

 Okarita. 



Gahnia liectori, Kirk; Trans. N.Z. Inst., IX., p. 551. 

 A vei-y distinct species, allied to G. procera, Forst. 

 North and South Islands — As far south as Okarila. 



Carex chlorantha, Brown ; Prodromus, 242. 



A small rat'ier 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 — Waltemata.
