Graminee. | FLORA OF NEW ZEALAND. 299 
Generally a taller plant than D. Billardieri, with many more, much smaller pale-green spikelets. Culms 1-3 
feet high. Leaves flat, broad or narrow, quite smooth or scabrous. Panicle 4-8 inches long, of very numerous, 
whorled, slender branches, that do not generally divide so soon as in the former species. Pedicels very slender. 
Spikelets $-$ inch long. Glumes smooth, except along the keel, twice as long as the flower, and half as long as the 
awn. Lower palea very silky all over, truncate, the teeth produced into short points, awn inserted at the middle. 
Upper palea shorter, blunt or two-toothed.  Sefula generally very small. This plant is the vena filiformis of 
Forster in Herb. Hook., and also of Labillardióre in Herb. Hook. Mr. Brown however refers Labillardidre’s 
plant to his D. Billardieri, with which the figure in Lab. Plant. Nov. Holl. agrees. This appears as common and 
variable a plant in Australia, Tasmania, and New Zealand, as Agrostis canina is in Europe; its synonymy is much 
involved.

A small, wiry, tufted Grass, of a different habit from the preceding.— Culms 6-8 inches high. Leaves very 
harrow, filiform or setaceous, smooth or rough to the touch, wiry, shorter than the culms, Skeaths short. Panicle 
1-2 inches long, narrow, contracted, sparingly branched, of few, erect, pedicelled, pale, shining spikelets 14-2 lines 
long. Glumes acuminate, rather longer than the flower. Lower palea more or less silky, truncate, toothed or 4- 
cuspidate at the tip. Awn inserted at the middle, rather longer than the glumes, curved or bent inwards. Upper 
palea shorter than the lower, with two teeth at the truncate top, longer than pedicel, which has very long, silky 
hairs.— PLATE LXV. B. Fig. 1, spikelet; 2, flower; 3, pistil and scales :—all magnified.
