Art. LXI.—Contributions to the Botany of Otago.
[Read before the Otago Institute, 17th January, 1878.]
With the exception of three or four species mentioned to indicate an extension of their range of distribution, the following plants have not been enumerated in any previous contribution to our knowledge of the flora of Otago.* Most of them were observed during hasty visits to portions of the district in the winter of 1874 and the summer of 1876–7, both under circumstances which prevented my paying more than cursory attention to purely botanical subjects. A few species are mentioned on the authority of the “Handbook of the New Zealand Flora,” and others on the authority of
[Footnote] * For a Sketch of the Botany of Otago, by J. Buchanan, see Trans. N.Z. Inst., I., p. 22. On Plants collected near Invercargill, by J. S. Webb, V., p. 360. Notes on Otago Plants, by G. M. Thomson, IX., p. 538.

specimens communicated by Mr. D. Petrie and Mr. G. M. Thomson, to whom I have great pleasure in expressing my thanks.
The chief interest of the following list consists in the corrected views it affords of the relative proportion of Glumiferœ, especially of the cyperaceous section, to other phænogams in the south; the Gramineœ are increased one-fourth and the Cyperaceœ nearly doubled as compared with Mr. Buchanan's Catalogue, in which the latter form less than one-twentieth of the entire number of flowering plants, a striking contrast to the ordinary proportion in the North Island which is one-tenth. The present list shows that the actual proportion in Otago is one-thirteenth, and that the small disparity which really exists is chiefly due to the deficiency in Cladium and Schœnus, which, although abundant in the north, are represented in Otago by a single species of the former and two of the latter. On the other hand all the New Zealand Carices are found in Otago with the exception of C. chlorantha, Br., C. colensoi, Hook. f., and C. stellulata, Good.; the last two will certainly be found within the district, but the first is restricted to the North Island where it is very local.
I hope to consider the chief points of interest in the distribution of Otago plants in a future paper.
It is a subject for regret that we know so little of the flora of Stewart Island and the Snares, which exhibit features of great importance. Little as we know of both, the flora of Stewart Island shows a connection between the peculiar plants of the south-west coast of Otago on one side, and those of the Chatham Islands on the other—while that of the Snares shows a connection with the Auckland Islands and the Chathams, apparently more close than that with the nearest portion of the main land. I venture to suggest to the members of the Otago Institute the propriety of making arrangements for the systematic investigation of the flora and fauna of these little known portions of their district.

Euphrasia repens, Hook. f. Bluff Island—Handbook.
Plantago spathulata, Hook. f. Near Invercargill—J. S. Webb!
brownii, Rapin. Mountains above Lake Harris. The Otago plant is nearly glabrous, and in several respects approaches the Auckland Island form, figured on table 43 “Flora Antarctica,” I., more closely than specimens from any other locality.
Chenopodium detestans, Kirk. Cultivated land near the outlet of Lake Wanaka.
Atriplex patula, L. Abundant on disturbed silt, Cape Whybrow.
Salsola kali, L. Ida Valley—D. Petrie! The Otago plant is less robust than the Australian form naturalized on the banks of the Waitemata, and, from its occurrence in company with Chenopodium pusillum in this remarkable inland locality, must be considered indigenous. Both plants are usually littoral, but are found in inland localities marking the site of ancient sea margins or exhausted brine springs.
Rumex neglectus, T. Kirk. West Coast of Otago—J. Buchanan! Bluff Harbour—T.K.
Pimelea virgata, Vahl. A remarkable form, white, with a dense covering of silky hairs on the leaves, is plentiful on the Cardrona range.

Exocarpus bidwillii, Hook. f. Bed of the Waitaki—Handbook.
Fagus cliffortioides, Hook. f. Valley of the Dart. The spray of this species more closely resembles that of the European beech, F. sylvatica, than the other New Zealand species.
Libocedrus bidwillii, Hook. f. Near Dunedin, etc. This is doubtless the L. doniana of Mr. Buchanan's Catalogue of Otago Plants.
Dacrydium bidwillii, Hook. f.
West Coast of Otago—Dr. Hector!
Chiloglottis cornuta, Hook. f. The Bluff Hill.
Prasophyllum pumilum, Hook. f. Several imperfect specimens collected on the Bluff Hill appear identical with this species.

Potamogeton oblongus, Vir. Near Invercargill—J. S. Webb.
P. pectinatus, L. Waihola Lake.
Astelia grandis, Hook. f. This is in part the A. nervosa of Mr. Buchanan's Catalogue.
[A. banksii, A. Cunn. Plants in the Dunedin Botanic Garden are said to have been found on “cliffs, near Dunedin,” but the alleged habitat is extremely improbable and requires examination.]
Juncus lamprocarpus, Ehr. Plentiful about Invercargill; Bluff.
β. Ditches near Kew railway station.
Schœnus axillaris, Hook f. The Bluff Hill.
Eleocharis sphacelata, Br. Bluff Island—Lyall, “Handbook.” This habitat requires confirmation; the nearest authenticated habitat is in the Taupo country—fully 600 miles distant.
acuta, Br., var. platylepis. E. gracilis of Mr. Buchanan's list, and of Fl. N.Z., not of Brown.
gracillima, Hook. f. Bluff Harbour, etc.

breviculmis, Br. The Bluff Hill.
neesiana, Endl. Catlin River.
dissita, Soland. Catlin River.
Microlœna stipoides, Br. In a single locality near Oamaru—perhaps a recent introduction. It is, however, certainly native to Westland.
avenacea, Hook. f. Lake Wakatipu.
Apera arundinacea, Hook. f. Water of Leith, etc.
Agrostis canina, L., var. subulata. Lake Wanaka, etc.
billardieri, Br. Cape Whybrow.

Poa imbecilla, Forst. Balclutha, etc.
Festuca littoralis, Br. Near Cape Whybrow.

2. This species is only known from Forster's original specimen in the British Museum.
Lindsaya viridis, Col. West Coast—J. Buchanan.
Lomaria dura, Moore. West Coast Sounds—J. D. Enys! Catlin River—D. Purdie and P. Thompson! Bluff Hill—T. Kirk. In situations exposed to the spray of the sea.
Lycopodium laterale, Brown. Stewart Island—Mrs. Pearson!
Panax lessonii, DC. Said to occur on the west coast of Otago, but it is to be feared that some mistake has been made. The plant appears to be confined to the Auckland district.
Pimelea urvilleana, A. Rich. Mentioned in Mr. Buchanan's list, but I greatly fear that some other species has been mistaken for it.
Potamogeton heterophyllus, Schreber. Included in the lists of Mr. Buchanan and Dr. Lindsay, but must be expunged as it is not a New Zealand plant. Young states of the so-called “P. natans” which developes copious submerged leaves have been mistaken for it throughout the colony.
Dichelachne stipoides, Hook. f. Included in Mr. Buchanan's list, but the precise locality forgotten. It is a northern plant finding its southern boundary at the East Cape, and is, at best, of extremely improbable occurrence in any part of the South Island.
Lomaria pumila, Raoul. Mr. Buchanan informs me that he mistook a small form of L. membranacea, Colenso, for this species. It is, however, not unlikely to occur on the west coast.
The following species may be expected to occur in the district, and should be carefully sought for:—
Olearia forsteri, Hook. f. Gahnia hectori, T. Kirk.
