847 Isachne australis. — Opunake (Taranaki), Kirk! The most southern locahty known to me.

858 Stipa setacea. — I have received numei'ous 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.

874 Dichelachne sciurea. — Vicinity of Westport, Tmvnson !

888 Danthonia oreophila. — Source of Nigger Creek, Canter- bury Alps, Dr. Cockayne.

894 Arundo conspicua. — Add to the synonyms Agrostis Les- soniana, Steud. Norn. ii. 41, and A. procera, A. Eich. Fl. Nouv. Zel. 125.

902 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 scojxtria ot the "¥ova, Antarctica," which is apparently confined 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 Astoni. The two plants may be thus characterized : —

3. P. Astoni, Petrie in Trans. N.Z. Inst, xxxviii. (1906) ined. — Culms densely tufted, 12-15 in. 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 2-2|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) ; Btich. N.Z. Grasses, t. 55a.
