Art. XXXVIII.—On a Collection of Plants from the Solanders.
[Read before the Philosophical Institute of Canterbury, 4th November, 1908.]
The Solanders are two small islands lying in the Tasman Sea, twenty-two miles south of the southward coast of the South Island, and W. ½ S. thirty-five miles from the north-west end of Stewart Island. The largest island, Solander Island, is nearly a mile in length, and rises abruptly from the sea to a height of 1,100 ft. The other island, much smaller, lies a mile to the westward.
On the 22nd October, Captain J. Bollons, of the G.s.s. “Hinemoa,” while searching for a missing vessel, landed on the main island, and, eager as he always is to advance our knowledge of New Zealand natural history, made, together with Mrs. Bollons, a collection of the plants. This he was so kind as to hand over to me, and I hasten to bring before your notice this first collection of plants made on this isolated island.
As seen from the appended list, nineteen species were collected, of which four are ferns. The vegetation is evidently closely allied to that of the outlying islands of the Stewart Island group, on the one hand, and, more distantly, to the coastal scrub of the West Coast Sounds, on the other. Poa foliosa and Senecio Stewartiœ also connect it with the Snares. Neither of these two plants has been found on the South Island, nor has the Senecio been recorded from Stewart Island itself, though it is fairly common, I understand, on the small outlying islands. The Stilbocarpa differs from that of Stewart Island, being much more hairy, of a rather dull green, and the small veins on the back of the leaf are much raised, making it almost lacunose. It increases by means of runners, as does the Stewart Island plant, and consequently differs altogether from the Snares plant, with its massive rhizome and no runners.
A more searching examination than Captain Bollons was able to give will probably show that other plants are present. One would certainly expect Olearia angustifolia, Scirpus aucklandicus, S. cernuus, Gentiana saxosa, one or two species of Hydrocotyle, and probably certain common coastal plants; also, the higher parts of the island not visited should have species not found at a low level.
