XCII. GRAMINEAS. 
Isachne australis.— Opunake (Taranaki), Kirk! The 
most southern locality known to me. 
Stipa setacea.—I have received numerous specimens of 
this from various localities on the east coast of the South 
Island, from Marlborough to Otago. It is evidently spreading 
rapidly, and no doubt can be entertained of its exotic origin. 
Dichelachne sciurea.— Vicinity of Westport, Townson ! 
Danthonia oreophila.—Source of Nigger Creek, Canter- 
bury Alps, Dr. Cockayne. 
Arundo conspicua.—Add to the synonyms Agrostis Les- 
soniana, Steud. Nom. u. 41, and A. procera, A. Rich. Fl. Nouv. 
Zél. 125. 
Poa litorosa.—In a communication made to the New Zea- 
land Institute in October, 1905, but not yet printed, Mr. 
Petrie has pointed out that the Festuca scoparia of Hooker's 
Handbook, which answers to the Poa litorosa of this work, 
is really composed of two species—one the original Festuca 
scoparia of the ‘‘ Flora Antarctica,’ which is apparently con- 
fined to the outlying islands to the south of New Zealand ; the 
other a very different plant, occurring on the rocky coasts of 
southern Otago and Stewart Island, as well as on the Auck- 
land Islands, and for which he proposes the name Poa Aston. 
The two plants may be thus characterized :— 
3. P. Astoni, Petrie in Trans. N.Z. Inst. xxxviii. (1906) 
ined.—Culms densely tufted, 12-ldin. high. Leaves equalling 
or exceeding the culms, very narrow, linear-filiform, gradually 
narrowed into an almost pungent point, closely involute, 
striate, glabrous; sheaths long, compressed, striate; ligules 
broadly triangular, acute. Panicle 2-24}in. long, ovate or 
ovate-oblong, rather dense ; branches short, simple or divided. 
Spikelets compressed, ovate-oblong, $in. long, 5—6-flowered. 
Two outer glumes about half as long as the spikelet, subequal, 
broadly lanceolate, acuminate, glabrous, 3-nerved. Flowering 
glumes ovate-lanceolate, acuminate, keeled, strongly 5-nerved, 
usually with a tuft of crisped hairs on the callus and lower 
part of the keel, but frequently without. Palea linear-oblong, 
bidentate, ciliate-scabrid on the keels.—Festuca scoparia, 
Hook. f. Handb. N.Z. Fl. 341 (in part, but not of Fl. Antarct. 
i. 98); Buch. N.Z. Grasses, t. 505A. 
SoutH Isntanp: Rocky cliffs on the coast-line of Otago and Stewart 
Island, not uncommon. AUCKLAND IsuAnDs: 7. Kirk !
