Notes on Individual Species

Campylopus bicolor (Hornsch.) Hook. f. This species, first gathered locally in Kaikorai Valley in 1879, is interesting, “from having many leaves of type form, obtuse and hairless, others with distinct hair, and others tapering without hair” (Sainsbury).

Campylopus clavatus (R. Br.) H. f. and W. To this species Sainsbury attributes Campylopus insititius, and possibly Thysanomitrium leptodus. I have retained the separate records for these species in the meantime.

Dicranum pumilum Mitt. Since Hector first collected this moss in 1863 on “dry ground, Otago,” it had not been subsequently seen till Allison recently gathered it on rocks near the Waipori powerhouse.

Dicranoloma robustum (H. f. & W.) Par. Numerous intermediate forms between this and var. setosum have been gathered on the summit of Maungatua by Simpson and the writer.

Eurhynchium praelongum Hobk. This moss is extremely abundant in Bethume's Gully and other Dunedin localities and fruits freely. It is an indigenous moss that has invaded plantations and lawns and in some places become the dominant moss. Possibly in some cases it may have been introduced.

Hennediella macrophylla (R. Br. ter.) Par. Numerous recent gatherings of Hennediella by Allison and the writer have made it clear that only one variable species is involved. This opinion of Sainsbury is shared by Allison and myself. Even the genus is scarcely to be distinguished from Pottia.

Hypnodendron arcuatum (Hedw.) Mitt. The writer recently obtained on a stream-bank near the summit of Swampy Hill, Dunedin, an aquatic form of this moss bearing small tufts of radicles on the stems. It is the absence of radicles that distinguishes this genus from Mniodendron.

Hypopterygium novae-seelandiae var. nudicaule Dix. In his Studies in the Bryology of New Zealand, Dixon, on p. 295, reports having received specimens from three localities all in the North Island. Two of these localities, however, are in the Dunedin Subdistrict in the South Island—viz., Blueskin, Waitati (wrongly spelt Waititi), and Purakanui (spelt Papakami), in which localities Berggren collected this moss in 1874.

Neckera brownii Dixon. Until recently this moss was known only from Banks Peninsula and one other unspecified locality. In 1949 Allison recorded it from the Dunedin area; but prior to this the writer had gathered it on Otago Peninsula, at Bluff, at Invercargill, and on Stewart Island. He has since obtained it from Waipori Gorge, Blue Mountains (Tapanui), Riverton, and Tuatapere. It would appear to have its centre of New Zealand distribution in the South Otago Botanical District in common with such other moss species as Goniobryum subbasilare, Isopterygium limatum, or Rhizogonium pennatum.

Neckera laevigata H. f. & W. On p. 463 of the Handbook of the N.Z. Flora, Hooker records this species as having been collected at Queensland Bush by my grandfather. The correct name of the locality is Green Island Bush, where for a time my grandfather resided.

Orthorrhynchium elegans (H. f. & W.) Reichdt. Sainsbury (Bryologist XLI, No. 1, p. 18), discussing Vegetative Reproduction in Some New Zealand Mosses, states that he has only once seen this moss with the deciduous habit. Both in the Dunedin area and in other parts of Otago and Southland, as well as at Butterfly Creek, near Wellington, the writer has observed stems with deciduous leaves. Commonly the young leaves near the tip and the lowermost leaves alone remain on the stems. The plants were fully as robust as other plants. Indeed, a majority of the plants in each area studied displayed the deciduous habit.

Pleuridium arnoldii (R. Br. ter.) Par. Petrie first obtained this diminutive moss on Swampy Hill, near Dunedin. Allison and the writer have recently noted it both on Flagstaff and on Swampy Hill, while I have also gathered it on Maungatua at 2,600 feet altitude.

Psilopilum bellii Broth. William Bell first obtained this moss at Pine Hill and on Mt. Cargill, but diligent search by subsequent botanists failed to locate it till the present year, when Allison detected it near the Leith Saddle.

Sciadocladus spp. Hitherto it has not been known whether only one or both species of Sciadocladus was present in the local moss flora. This was because fruiting plants were not known and the gametophytes are indistinguishable. The discovery of fruiting plants of S. menziesii collected by Petrie on Mt. Cargill, and of S. kerrii, collected by Allison on Swampy Hill, however, makes the position clear; but whether all records are attributed to the correct species in the absence of sporophytes seems open to question.

Sciaromium bellii Broth. There is general agreement with the opinion of Sainsbury that the moss so named is only an aquatic form of the sub-aquatic moss Campylium relaxum now named Cratoneuropsis relaxa. There have been several recent local gatherings of the aquatic form, but Sciaromium is now deleted from the New Zealand flora.

Seligeria cardotii. A moss gathered by me near Waipori may be this species, but better material is needed for accurate determination. The species has not been included in the list of species.

Sphagnum spp. S. cymbophylloides, S. dielsianum, S. magellanicum, S. otagoense, and S. sub-bicolor all present in this district have now been merged by Le Roy Andrews as forms of S. leionotum. Similarly the following members of the Cuspidata section—viz., S. irritans, S. kirkii, S. linguaefolium, and S. subcuspidatum, noted locally—are included as forms of S. falcatulum. These and S. antarcticum are the only local Sphagna.

Tortula submutica Broth. Sainsbury has pointed out that this species must be dropped as the Anderson's Bay plant is T. phaea.
