Norru Istanp: Rocky or sandy places near the sea, from the North Cape 
to the Bay of Plenty, abundant. 
Not uncommon in Australia and Tasmania. Hooker quotes Agrostis rigida, 
A. Rich., as a synonym, but Richard’s description does not suit, and his plant 
was gathered in the French Pass, near Nelson, far beyond the southern limit of 
S, teretifolia. 
3. S. setacea, &. Br. Prodr. 174.—Culms tufted, slender, wiry, 
erect, glabrous, 1-2 ft. high. Leaves numerous towards the base 
of the culms and much shorter than them, very slender, almost 
filiform, erect, smooth, involute; sheaths closely appressed, smooth ; 
ligules narrow, membranous. Panicle lax, strict, erect, glabrous, 
4-8 in. long; rhachis smooth; branches whorled, capillary, each 
with 2-5 spikelets ; pedicels minutely scaberulous. Spikelets 4 in. 
long without the awn, pale whitish-green. Two outer glumes 
almost equal, lanceolate, acuminate, very thin and membranous, 
almost hyaline, glabrous; 3rd or flowering glume much shorter, 
rigid, convolute, brownish, densely villous, entire at the tip; awn

A common Australian plant, stretching from Queensland to Tasmania. It 
is probably naturalised only in New Zealand.
