pilose. Leaves very coriaceous, concave, rigid, 1-2 ft. long, ^ in. broad, 
glabrous or hairy on the upper surface ; sheaths broad ; ligule 0, or a line of 
long hairs. Panicle very open, lax, 8-12 in. long; branches many or few, in 
distant pairs, very slender, 4-8 in. long, pubescent. Spikelets alternate on 
the branches, shortly pedicelled, \ in. long, 2-S-flowered. Empty glumes 
unequal, lanceolate or linear-oblong, lower acute or obtuse ; flowering £ 
in. long, narrow, glabrous, except at the base and sides where covered with

Northern Island : Bay of Islands, shady woods, Keri-Keri river, A. Cunningham ; woods 
near the tops of the Ruahine mountains and Hawke’s Bay, Colenso. Middle Island : up- 
lands near Otago, Lindsay ; lake district, Hector and Buchanan. 
2. D. bromoides, Hook. f. FI. N. Z. i. 303. t. 68 A. Culms and 
leaves as in D. Cunninghamii, but panicle much smaller, oblong or lanceolate, 
4-6 in. long, contracted ; branches 1-2 in. long, erect. Spikelets broader, 
glumes closer, more like those of B. Raoulii. Awn not flattened nor twisted,

3. D. Raoulii, Steud. — B. rigida, Raoul ; — Hook. f. FI. N. Z. i. 303, not 
Steud. Habit and character of B. Cunninghamii, but leaves involute and 
filiform ; spikelets longer, pedicelled, larger, f in. long, broader ; glumes 
larger, both empty ones long acuminate, the flowering closely imbricate, broader, 
and the awn is flattened and twisted in a corkscrew manner at the base. 
Northern Island : from halfway up to the tops of the Ruahine range, and hills on the 
east coast, Colenso. Middle Island: Akaroa, Raoul ; common in the Alps, ascending to 
3000 ft., Sinclair and Haast ; Milford Sound, Lya/l ; Tarndale, Sinclair ; Otago, lake 
district, alt. 2000 ft., Hector and Buchanan. Very like indeed the B. Cunninghamii, in 
some respects, but 1 think quite distinct : it is more near B. robusta of the Victorian alps. 
The leaves in all specimens from all elevations are almost filiform.
