Cheeseman. — Revision of the N.Z. Species of Carex. 43? 



29. C. cheesemanii, Petrie, Trans. N.Z. Inst., xv., 358. 



South Island. — Apparently common in hilly and mountainous districts. 

 Wairau Valley ; Buller Valley ; AVangapeka Valley and other localities in 

 the interior of Nelson, T.F.C. Upper Waimakariri and near Mount Dob- 

 son, Canterbury, T.F.C. Upper Waipori ; Strath Taieri ; Maniototo Plain ; 

 Nevis Valley and other places in Otago : D. Petrie ! G. M. Thomson ! 



This is probably nearest to the preceding species, and although differing in 

 several characters migbt well be regarded as a variety only. The culms are 

 longer and more slender, often considerably exceeding the leaves ; the leaves 

 are flatter and rather narrower, although variable in this respect ; the lower 

 spikelets are usually on long filiform peduncles ; and the glumes and 

 perigynia are rather broader. Like several other New Zealand species it 

 is often a red-brown colour. Large and coarse specimens have some slight 

 outward resemblance to small forms of C. lucida, but in reality differ alto- 

 gether in leaves, glumes, and perigynia. 



30. C. littoralis, Petrie, Trans. N.Z. Inst., xv., 358. 



North Island. — Probably not uncommon in brackish-water marshes. 

 Whangarei Harbour ; Manukau Harbour ; marshes by the Thames and 

 Piako Eivers ; Tauranga Harbour, T.F.C. 



South Island.— Nelson Harbour and marshy places by the shores of 

 Blind Bay, T.F.C; Port Chalmers; Paterson's Inlet (Stewart Island), 

 D. Petrie ! O. M. Thomson ! 



This species appears to be confined to brackish-water swamps. It has 

 been confounded with C. testacea, with which, however, it has little affinity. 

 It is nearer to C. comans, but is easily recognized by its larger size and 

 stouter habit, more closely placed spikelets, and particularly by the more 

 turgid biconvex or trigonous perigynia, not (or very obscurely) serrate above. 



31. C. dissita, Solander, mss. ; Boott in Rook. Jil. Flora Nov. Zeal., i., 

 284; III. Car., i., t. 176 ; Hook, fi I. Handbk. N.Z. Flora, 316. 



North and South Islands.— Abundant in most districts, and ranging from 

 sea-level to 3,500 feet, alt, 



Var. /3, lambertiana. — Much stouter, leaves broader, sometimes over J 

 inch. Spikelets much longer and stouter, sometimes 2^ inches long, erect, 

 short stalked. Glumes more deeply bifid. C. lambertiana, Boott in Hook, 

 fil. Fl. Nov. Zeal., i., 284 ; Handbk. N.Z. Flora, 317. 



North and South Islands. — Apparently not uncommon throughout. I 

 have not myself seen specimens from Otago, but I am informed by Mr. Kirk 

 that it occurs both there and in Stewart Island. 



Var. y. — Culms usually overtopped by the leaves ; spikelets paler, short- 

 stalked, lowest often compound ; glumes with longer awns. 



North Island. — Common in the Auckland Provincial District.
