North Island.—Near Auckland, T. Kirk, T.F.C.; Thames Valley, Upper 
Waikato and Waipa, T.F.C.; Hawke's Bay and Ruahine Range, Colenso 
(Handbook); Waimarama, Hawke's Bay, H. Tryon! Wellington, rare, 
South Island.—Wangapeka Valley, Buller Valley, and other localities in 
Nelson Province, T.F.C.; Canterbury, Armstrong (Trans. N.Z. Inst. xii., 
344); Otago, Lake Wanaka, Outram, and Strath Taieri, D. Petrie! Deep 
Stream, G. M. Thomson! Dart Valley, T. Kirk. Altitudinal range from 
sea-level to over 3,000 feet. 
Var. radicata.—Smaller, 2-4 inches high. Culms short or almost want- 
ing, so that the spikelets are nearly radical, and much overtopped by the 
leaves ; leaves wiry, involute, filiform ; perigynia prominently nerved, nar- 
rowed into a long tapering serrate beak. Lakes Tekapo and Pukaki, 
Canterbury, altitude 2,500 feet, T.F.C. 
The species, which is also common in many parts of Australia and Tas- 
mania, can be easily distinguished from the following by its grassy habit, 
pale-coloured spikelets, and beaked perigynia. It varies greatly in height— 
some of my Nelson specimens are over eighteen inches, and Mr. Kirk 
informs me that he has gathered equally luxuriant ones in the Wellington 
District. On the other hand, specimens from the Upper Waikato are much 
depauperated. 
The variety to which I have applied the name radicata is a very distinct 
looking plant, but as at present it is only known from one district I hesitate 
to describe it as a new species. It differs markedly from the type in the 
very short culms, involute filiform leaves, and longer beak to the perigynia ; 
but the Australian variety major has perigynia very similar in shape, and 
the length of the culms is a variable character in most of the species. Pos- 
sibly some of its characters may be due to the dry and arid climate of the 
district in which it was collected.

North Island.—Probably not uncommon on the dry grassy plains in the 
interior. Upper Thames and Patetere, 7.F.C.; Patangata, Hawke’s Bay,

South Island.—Oommon throughout in hilly and grassy districts, ascend- 
ing to 4,500 feet. Sinclair and Haast (Handbook); Travers (Handbook) ; 
Buchanan! Armstrong! D. Petrie! G. M. Thomson! T.F.C. 
A distinct and well-marked species, apparently confined to New Zealand.
