Art. XXXVI.—Some Recent Additions to the Moss-Flora of New Zealand.

[Read before the Philosophical Institute of Canterbury, 20th November, 1898.]

The fourth part of Dr. V. F. Brotherus's work on “New Species of Australian Mosses,” published early this year, contains descriptions of fifteen new species from New Zealand, collected by Mr. William Bell in Otago, Mr. D. Petrie in Auckland, and by myself in Canterbury. I have in this paper given his descriptions of these additions to our moss-flora, together with several other mosses now for the first time recorded from New Zealand.

Eucamptodon petriei, Broth., n. sp.

Dioicus; valde robustus, rigidus, lutescens, nitidus; caulis 6 cm. altus, flexuosus, dichotome ramosus, dense foliosus; folia scariosa, patentia, stricta, valide canaliculato-concava, ovato-lanceolata, obtusa, superiora 7—7.5 mm. longa et c. 2.5 mm. lata, marginibus erectis integerrimis, limbata, limbo angustissimo, hyalino, apicem versus evanido, nervo tenuissimo, paulum ultra medium evanido, interdum obsolete, cellulis elongatis, inter se valde porosis, basilaribus aureis, alaribus permultis, pachydermis, quadratis, fusco-aureis omnibus lævissimis. Cætera ignota.

Patria (No. 641).—Teremakau Valley, Westland; D. Petrie.

“Species pulcherrima, distinctissima cum E. macrocalyce, C Müll., comparanda, sed statura multo robustiore, foliis nervo tenuissimo præditis aliisque notis raptim dignoscenda.

“That moss from Tasmania which my friend A. Geheeb, under the name of Dicnemon moorei, Broth. Geh., mentions in ‘Revue Bryologique,’ 1897, p. 67, I have by a further examination found to be Campylopus kirkii, Mitt., earlier found in New Zealand.”—“New Species of Australian Mosses,” by

Cheilothela.

I am indebted to Mr. A. Gepp, of the British Museum, for the following translation from the original Swedish of Dr. S. O. Landberg's description of his new genus Cheilothela in “Utkast till en naturlig.,” 1878:—

Ditricheæ includes Bryoxiphium, Swartzia, Ditrichum, Pleuridium, and Archidium. To these is how joined this new genus, Cheilothela, with the single species Ch. chloropus (Ceratodon, Brid.), occurring in Italy arid Southern France—

– 428 –

a genus which can in no wise be compared with Ceratodon, by reason of the channelled, and, in the dry state, erect and appressed, leaves, with strong flattened-out and not limited nerve, forming the uppermost acute dagger-like part of the leaf; the small quadrate cells, with both upper and lower ends lip-formed, protruded exactly as in Swartzia, or a multitude of the Bartramiaceæ; perichætial bracts which are never reduced to mere basal-scales, the perfect Trichostomum-like peristome, &c. Similarly it can be little referred to the Tortuleæ, but it is to be considered in the light of a link between Swartzia and Ditrichum.”

“My excellent friend Mr. T. W. Naylor Beckett has sent me, under No. 609, specimens from Tyson's Mill, Otago, which I only with hesitation can refer to the species described above. It is somewhat coarser, and the leaves are projecting, which gives it a different aspect. Nevertheless, when its anatomical structure does not show any difference I dare not yet describe it as a separate species.”—V. F. B., op. cit., p. 101.

In the “Transactions of the New Zealand Institute,” vol. vi., p. 210, the late Mr. J. Buchanan published a paper on the mosses of the Province of Wellington, New Zealand, containing five new species named by. Dr. J. Stirton. Dr. Stirton informed me that he had received the mosses from Mr. Buchanan, but was unable to say in what publication he had described them. On referring the question to Mr. A. Gepp, of the Natural History Department, British Museum, he kindly instituted a search, and sent me the following extracts from the Trans. Nat. Hist. Soc. Glasgow. He added that he had failed to find in any periodical the description of three of them—viz., Hypnum amiatum, Hypnum wellingtoni, and Weissia rufa.

Grimmia buchanani, Stirton.

“Stems loosely tufted; leaves oblong amplexicaul, plane margined, laxly areolated, terminating abruptly in very long, green, nearly entire subulæ, which are composed almost entirely of the prolonged nerves; perichætial leaves longer and narrower at the sheathing bases, otherwise identical; fruitstalk curved; capsule ovate, regular, furrowed when dry, pale; lid conico-rostrate, oblique, more than half the length of the capsule; calyptra dimidiate, covering half the capsule; teeth deep-red at base, curved, bifid into long pale subulate points; inflorescence in all likelihood dioicous; antheridia not detected.”—Dr. J. Stirton, in Pro. Nat. Hist. Soc. Glasgow, vol.ii. (1876), p. 187.

Dr. Stirton sent me this moss with the remark, “Dr. K. Müller refers Grimmia buchanani to another genus.” I at once recognised it as Dicranodontium flexipes, Mitt., and Dr. Brotherus has confirmed my identification. Dr. Stirton does not possess specimens of the other mosses described below.

Since the above was written I have received from Dr. Karl Müller a copy of his Symbolæ ad Bryologiam Australis (Hedwigia, xxxvii., 1898), in which (p. 116) he describes this moss. He considers it a new species, and publishes it under the name Angströmia (Campylopodium) buchanani. He adds, “In Hb. Stirton sub nomine Grimmiæ buchanani ejusdem fuit. Campylopodium capillaceum (H. f. et W. sub Dicrano) insulæ septentrionalis caule dicranoideo fere pollicari uncinate primo visu distinguiter.”

Tortula incurvidens, Stirton.

“Stems gregarious, short; leaves lanceolate, with plane entire margins, crisped when dry, texture dense, opaque above, pellucid and quadrangular at base, nerve strong, indistinct near the apex, which is somewhat cucullate; capsule red, erect, on a thick red seta; peristome arising from a basilar membrane, broad and prominent above the mouth of the capsule, irregular, rough with minute papillæ, and crossed by two or three septa, incurved when dry, converging into a cone when moistened; lid obliquely rostrate, subulate, nearly as long as the capsule; calyptra dimidiate, extending more than half-way down.

“Approaches in several of its characters to Tortula ambigua, but diverges in others.”—Stirton, op. cit., p. 187.

Bryum contortum, Stirton.

“Dioicous, densely cæspitose; stem radiculose; lower leaves small, scattered, upper suddenly enlarged, closely imbricated in a moist state, contorted when dry, ovate-oblong, terminating in long smooth reflexed points formed by the

excurrent nerves, which are red in the substance of the leaves; margin slightly reflexed, not thickened, but composed of two or three rows of narrower cells than those of the rest of the pagina; seta long, stout, red; capsule red, pendulous, narrowly obconical; lid sharply conical, apiculate, deep-red, shining.

“Allied to Br. obconicum.”—Stirton, op. cit., p. 188.

Bryum bulbillosum, Montagne.

“Description of this moss in Müller's Synopsis (ii., p. 301) agrees pretty well with the character of the New Zealand moss, and, in the absence of any more definite indications, it has not been thought advisable to separate them.”—Stirton, op. cit., p. 188.
