Anthoxanthum erinitum, Forst. Prodr. n. 18. 
Var. intermedia, Hack. MSS.—Rather more slender ; panicle narrower and 
laxer. A passage form into D. scwwrea. 
Nortry anp Sours Isuanps, Stewart IstaAnD, CHATHAM IsLANDS: Plen- 
tiful in dry open situations throughout. Sea-level to 3000 ft. Also abundant 
in Australia and Tasmania. 
2. D. sciurea, Hook. f. Fl. Nov. Zel. i. 294.—Smaller than 
D. crinita and more slender. Culms tuited, 1-2 ft. high, slender, 
quite glabrous. ‘Leaves chiefly at the base of the culms and much 
shorter than them, narrow, flat or convolute, sometimes almost 
setaceous, glabrous or the lower ones pubescent; sheaths smooth ; 
ligules short, broad. Panicle 3-6 in. long, much more lax and open 
than in D. crinita; branches slender, capillary, scabrid. Spikelets 
1 in. long, rarely more. Two duter glumes equal or nearly so, long- 
acuminate, margins hyaline, keel smooth or scabrid ; 3rd or flower- 
ing glume nearly as long, convolute, smooth or slightly scabrous, 
entire or 2-fid at the tip; awn 4—3in. long, flexuous, usually but 
not invariably twisted at the base, inserted on the back of the 
glume close to the tip. Palea narrow-linear, 2-fid—Handb. N.Z.

Var. inequiglumis, Hack. MSS.—Panicle with longer flaccid branches ; 
spikelets more laxly arranged. Two outer glumes unequal, acute but not cus- 
pidate, keel sharply scabrid ; awn of flowering glume almost apical, not twisted 
at the base. 
Nortu Istanp: From the North Cape to Wellington; not so plentiful as 
D. crinita. SourH Istanp: Has been recorded from Marlborough (Buchanan), 
Canterbury (Armstrong), and Greymouth (Kirk), but I have seen no specimens. 
Also in Australia, Tasmania, and Norfolk Island. 
20. DESCHAMPSIA, Beauv. 
Perennial grasses. Leaves narrow, flat or convolute. Spikelets 
rather small, 2-flowered, arranged in lax or contracted panicles ; 
rhachilla disarticulating above the 2 outer glumes, produced between 
the flowering glumes and above the upper flower as a naked or 
hairy bristle, rarely ending in an imperfect flower. Glumes 4; 
2 outer slightly unequal, persistent, empty, keeled, acute, mem- 
branous, shining; 3rd and 4th (or flowering glumes) membranous or
