Bay of Islands and Auckland, Sinclair, etc. Also found in Tasmania and Australia. 
2. D. crinita, Hook, f, FI. N. Z. i. 293. Culms annual, tufted, 1-3 ft. 
high, slender or stout, leafy, glabrous downy or rather scabrid. Leaves flat 
or involute. Panicle elongate, contracted, dense, spike-like, shining ; branches 
almost hidden by the flexuous awns. Spikelet ^ in. long. Empty glumes 
narrow, long-acuminate, exceeding the flowering, which is scabrid, acuminate, 
entire or 2-fid at the tip ; awn capillary, inserted at the back above the 
middle, flexuous, not twisted, 1 in. long. — D. vulgaris and D. Forsteri- 
ana, Trinius ; Muhlenbergia mollicoma, Nees ; Agrostis crinita , Br. ; Apera 
crinita , Palisot ; Antlioxanthum crinitum, Labill. FI. Nov. Iloll. ii. 115.

Northern and Middle Islands : abundant in dry soil, Banks and Solander, etc. Very 
common in Australia and Tasmania. 
3. D. sciurea, Hook. f. FI. N. Z. i. 294. Very similar to D. crinita, 
but smaller, more slender ; panicle much thinner, with fewer spikelets ; 
empty glumes shorter, as long as the flowering; and awn twisted, not four 
times as long as the glume. — FI. Tasm. t. 158 A; I). Sieberiana, Trin. and 
Bup. ; Agrostis sciurea, Br. ; Slip a micrantha , Nees ; Muhlenbergia Sieberiana, 
Trin. 
Northern Island : Bay of Islands and Auckland, Cunningham, etc. I suspect this is 
only a variety of the former; it is also found in Australia and Tasmania. 
12. APERA, Adanson. 
Slender, erect, annual or perennial grasses. Leaves involute. Panicles 
with very long, capillary, whorled branches. — Spikelets minute, 1-flowered. 
Empty glumes 2, nearly equal, membranous, longer than the flowering, which 
is terete, coriaceous, acuminate, quite entire at the tip, ending in a very 
slender, straight, not twisted awn. Pale membranous. Scales 2, membra- 
nous. Stamens 1-3, Grain terete, enclosed in the coriaceous glume, free. 
A small European and North American genus. 
1. A. arundinacea. Hook. f. FI. N. Z. i. 295. t. 67. A tall, erect, 
densely tufted, glabrous, most graceful grass. Culms reed-like, with creep-

ceous, narrow ; margins involute, slightly scabrid ; sheaths long ; ligule short, 
truncate. Panicle erect, 8-1 6 in. long ; pedicels alternate on the long 
whorled branches. Spikelets minute, T y-To hi. long, pale, shining. Empty 
glumes with a scabrid keel ; flowering one sessile on a small glabrous callus, 
thickened and rough at the top ; awn scabrid, deciduous, i in. long. Scales 
linear. Stamen 1. Ovary pedicelled. Grain truncate. 
Northern Island: Cape Turnagain, Colenso ; Akaroa, Raoul. Also found in subtro-
