the culms, the lowermost reduced to appressed sheaths, upper 6-12 in. 
long, 4-4 in. broad, coriaceous, fiat or involute, margins and midrib slightly 
scaberulous ; sheaths very long, closely appressed, finely ciliate along the 
margins; ligules short, truncate. Panicles very large and lax, nodding, 
1-24 ft. long; rhachis very slender, glabrous; branches in distant whorls 
of 5-8, capillary, again compound, spreading, finely scaberulous, 3-6 in. 
long. Spikelets minute, ;4,-}in. long, greenish-purple. Two outer glumes 
almost equal, lanceolate, acuminate, membranous, scaberulous along the 
keel, lower 1-nerved, upper 3-nerved ; 3rd or flowering glume much shorter, 
sessile on a short glabrous callus, rigid, convolute, pubescent towards the 
tip; awn slender, scabrid, deciduous, about 4in. long. Palea linear- 
oblong, 2-nerved. Stamen 1.—Cheesem. Man. N.Z. Fl. (1906) 857. Apera

A very handsome species. It is closely allied to S. verticillata Nees (Streptachne 
ramosissima Trin.), an Australian species which is often grown in gardens, and which 
has established itself in several localities, but which differs in the rather larger spikelets 
with a much longer persistent awn, and in having 3 stamens.

2. S. teretifolia Steud. Syn. Pl. Gram. (1855) 128.—Culms densely 
tufted, forming large tussocks, ngid, erect, smooth and polished, quite 
glabrous, 14-3 ft. high. Leaves longer or shorter than the culms, slender, 
smooth, rigid, terete, about 4, in. diam., tips acicular ; sheaths long, margins 
scarious ; ligules membranous, entire. Panicle narrow, strict, erect, 4-9 in. 
long; rhachis smooth; branches few, erect, capillary, and with the pedicels 
glabrous. Spikelets narrow, about #in. long without the awn. ‘Two outer 
glumes subequal, lanceolate, acuminate, finely 3-nerved, membranous, pale 
whitish-green ; 3rd or flowering glume much shorter, ngid and convolute, 
lanceolate, acuminate, densely clothed with long silky hairs, shortly bifid 
at the apex; awn from between the lobes, often over lin. long, curved 
or abruptly bent, minutely pubescent. Palea ? the length of the flowering 
glume, linear, silky, 2-nerved. Stamens 3.—Benth. Fl. Austral. vii (1878)

Norru Istanp: Rocky or sandy places near the sea, from the North Cape to 
the Bay of Plenty and Raglan, 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 9. teretifolia,

culms and much shorter than them, very slender, almost filiform, erect, 
smooth, involute; sheaths closely appressed, smooth; ligules narrow,
