I am still doubtful whether the Auckland and Campbell Islands plant, originally 
described by Hooker as Bromus antarcticus, has been rightly merged by him with the 
North Island D. bromoides. It is much larger and stouter, with larger spikelets con- 
taining more numerous florets, and often forms tussocks 3-4 ft. high, attaining a size 
almost equal to that of D. Aaoulii, whereas the typical bromoides is rarely more than 
18 in. high. If further investigation should prove it to be distinct, there seems to be 
no reason why Hooker’s name of D. antarctica (Hl. Nov. Zel. i, 302) should not be 
reapplied to it, for although he also included the plant now known as D. Cunninghamu 
it was as a separate variety, the Auckland Islands plant being evidently treated as the 
type of the species. 
4. D. Raoulii Steud. Syn. Pl. Glum. (1855) 246.—Densely tufted, 
forming large brownish-green tussocks 2-5 ft. high. Culms stout or slender, 
smooth, often branched at the base. Leaves numerous, longer or shorter 
than the culms, variable in width at the base, gradually narrowed into 
long filiform points, strongly involute and rush-like when dry, coriaceous, 
smooth and polished on the back, ribbed on the inner face; margins 
smooth, glabrous or pilose just above the ligules; sheaths brownish, much 
broader than the blade, often lax and scarious towards the base, coriaceous 
above, glabrous or sparsely pubescent; ligules reduced to a transverse 
band of short dense hairs. Panicle variable in size, 4-18in. long, lax; 
branches few or many, divided, slender, filiform, smooth and glabrous ; 
pedicels long, often silky towards the tips. Spikelets 4-?in. long without 
the awns, 4-10-flowered. Two empty glumes unequal, from 4-2 the length 
of the spikelet, ovate-lanceolate, the lower 3-nerved, the upper 5-nerved, 
the lateral nerves usually short. Flowering glumes with long silky hairs 
at the base and on the margins for } their length or more, often also 
fringed on the lower part of the back, deeply bifid at the tip, the divisions 
usually produced into short scabrid awns, 7—-9-nerved ; central awn long, 
3-y10., straight or recurved, flattened and usually twisted at the base. 
Palea rather shorter than the glume, 2-nerved, silky on the nerves.—Buch.
