Notes On Individual Species.
1. Andreaea acutifolia. Mr. Sainsbury points out that if this determination is correct, the plants are exceedingly robust.
2. Blindia tenuifolia. Hitherto this moss has been regarded as comparatively rare in New Zealand, but on the mountains of Stewart Island it is very common (Mt. Anglem, Table Hill, Rakiahua, Thomson Range, etc.). On Table Hill it is exceptionally tall and robust, but Mr. Sainsbury reports similarly robust plants from Sulphur Springs, on Mt. Ruapehu.
3. Blindiopsis immersa. This aquatic moss has been found previously only twice, once at Arthur's Pass and once in the West Otago Sounds. The writer discovered it at Staircase Falls and also collected it on Table Hill, where it was detected by Miss Sheila Traill. The

presence of capsules in good condition enabled Mr. Sainsbury to confirm the generic status of the moss and the gymnostomous character of the capsules. It grows in stations where it must be almost perpetually submerged.
4. Isopterygium limatum. Hitherto regarded as a rare South Island moss, this proves to be one of the commonest epiphytes in Stewart Island. The writer has it from Arthur's Pass, from Woodside Creek in Marlborough, from Dunedin, from Invercargill, and from Bluff, where it grows on rocks and on rimu. It commonly grows as semi-detached brackets or cushions, and once was rooted in soil at the base of a rimu (Dacrydium cupressinum). It fruits copiously.
5. Macromitrium caducipilum. This moss has a distribution similar to that of Isopterygium limatum, being abundant on Stewart Island, at Bluff and Invercargill. Simpson and Thomson gathered it near Milton, and I have it from Dunedin, north of which its occurrence seems to be rare. I have gathered it at Titahi Bay near Wellington on coastal rocks.
6. Neckera brownii. This species was found on a single tree near the whaling station in Paterson Inlet, but it occurs plentifully in the Waihopai Scenic Reserve at Invercargill. I have it also from Otago Peninsula. Banks Peninsula and two North Island stations complete the list of its known occurrances.
7. Sciadocladus menziesii. So luxuriantly does this moss grow that at Glory Cove plants were gathered with as many as eight successive whorls of innovations. Whether these are produced annually is uncertain but probable. Not more than four whorls were noted on the related moss Mniodendron comosum.
8. Weisia viridula. Referring to this moss under the name W. controversa, Robt. Brown said, “It is very doubtful if it has a habitat in the South or Stewart Island.” It has, however, now been observed in Westland, in Canterbury, in Southland, and in Stewart Island.
9. Plagiochila ansata. A hepatic, so identified from Port William by Hooker, is suspected by Mrs. Hodgson (1944, p. 291) of being Jamesoniella colorata. The fact that this latter species alone of the two was gathered by me at Port William supports this view.
10. Lepidozia patentissima. Hepatics collected by me matching that identified by Stephani in Cockayne's collection are said by Mrs. Hodgson to differ from Taylor's type and to belong to an undescribed species.
11. Daltonia novae-zelandiae is a rather rare moss in New Zealand. In Stewart Island it is epiphytic on the deciduous bark of Fuchsia excorticata. Mr. Sainsbury considers it possibly conspecific with D. angustifolia Dz. and Mb.
12. Schlotheimia campbelliana. This moss previously believed to be confined to Campbell Island is common on Stewart Island, where aparently it replaces S. brownii of the main islands.
