length of culms, 1 line wide at base, sub ^ line wide above, 

 largely striate, tips subacute, whitish, callous, pale-green, 

 subglaucescent, scaberulous dotted between striae below, 

 closely revolute, finely hairy, largely sheathing, orifice of 

 sheath very hairy within. Raceme small, rather narrow, 

 lin.-l-|in. long, minutely scaberulous, bearing 5-7 upright 

 pedunculate spikelets ; at base a long leaf-like sheathing 

 bract, tip truncate with erect ciliae ; peduncles 1 line lon§ 

 scaberulous and slightly hairy, with a long linear scarious 

 bracteole at base. Spikelets not crowded, obovate, suberect, 

 4 lines long, containing 3-5 florets, with a small linear mem- 

 branous bracteole at base ; glumes and awns pale-green dashed 

 with purple ; outer empty glume 3 lines long, ovate, 10-nerved, 

 nerves bright-green, prominent, each forming a double line, 

 margin ample membranous, shining, white, tip obtuse its 

 margin scaberulous ; second empty glume margins scabrid, 

 tip jagged ; white hairs around base. Flowering - glume 

 deeply 2-fid, lateral awns very long, longer than glume and 

 nearly as long as central awn ; central awn long, flat, dark- 

 brown, shining and twisted below; awns scabrid, erect; two 

 bundles of long hairs on lateral margins of glume", hairs rigid, 

 unequal, scaberulous, acute. Palea subobovate, margins 

 sparingly hairy ; tip bifid, rigid-ciliolate. Ovary obovate, 

 brown, tip bi-cornuted to base of styles ; stigmas slightly

Hab. Dry hills, altitude l,000ft.-3,000ft., Hawkston, 

 County of Hawke's Bay : Mr. Thomas Hallctt ; 1894-95. 



Obs. I. The affinities of this species are with D. racemosa, 

 R. Br., and D. poiicUlata {Arunclo i)enicillata, Labill., PI. 

 Nov. HolL, i., 26, tab. 34), but differing in several characters. 

 Specimens received were obttiined after flowering. 



II. Mr Hallett kindly informs me that this grass makes a 

 close sward, but every plant only grows in its own simple 

 tuft. Cattle and sheep are very fond of it, and crop it closely. 

 It grows well during winter, and is about equal to most other 

 grasses during summer for grazing purposes ; and even while 

 being closely grazed it perfects seed, owing to its habit of 

 sending out many of its culms horizontally. A valuable grass 

 on unploughable hills.
