A Reference List of New Zealand Marine Algae. By Robt.M.LaingB.Sc., F.N.Z. Inst. [Read before the Philosophical Institute of Canterbury, 4th November, 1925; received by Editor, 12th December, 1925; issued separately, 17th November, 1926.] Introductory Remarks. Our knowledge of New Zealand seaweeds commenced with Cook's first voyage. The specimens collected by Sir Joseph Banks and Dr. Solander in 1769-70 were handed over to Dawson Turner and described by him in his Fuci sive Plantarum Fucorum Generi a Botanicis Ascriptarum, vol. 1, of which was published in 1808; and the final vol. 4 in 1819. The whole work is dedicated to the Right Honourable Sir Joseph Banks; and the first species is Fucus Banksii [i.e. Hormosira Banksii (Turn.) Decaisne]. These four volumes constitute the first English work of importance dealing with the seaweeds in general. Fucus Banksii however was not here described from New Zealand, but from New Holland, collected by Menzies and Brown, of Captain Vancouver's expedition in 1791 and presumably handed over to Sir Joseph Banks. There are however some fifteen species ascribed to New Zealand amongst those collected by Banks and Solander. Of Fucus Banksii Turner writes, “For my specimens of this most extraordinary Fucus, I am indebted to the Right Honourable Sir Joseph Banks by whose name I have called it, in memory of the kindness which he has always shewn to me, and of the exceeding liberality with which he has assisted me in the present publication.” The figure accompanying the description is that of an extremely mutilated but still recognisable specimen of Hormosira. Amongst the plants from New Zealand in this monumental work, the two most striking are probably Fucus maschalocarpus, and F. phyllanthus; these are now placed under the genus Carpophyllum. In the advertisement Turner concludes thus, “The author … feels a satisfaction in taking leave of his readers with the consciousness of having laid before them a set of figures, upon the accuracy of which they may rely, and which, as representations of things that are, will, through every change of human opinions, retain an undiminished value, while they may serve, in the hands of some more able, and more fortunate successor, as the ground work of that which he had hoped to accomplish himself.” Turner's claim is not extravagant, and is justified by the fact that for more than a century his volumes have remained the final court of appeal, for the specific names of many seaweeds. The next voyage of discovery to be mentioned is that of the French exploring corvette “Coquille,” 1822-24, under Captain Duperry, with Dumont D'Urville as one of his officers. More important however is the voyage of the “Astrolabe” (the “Coquille,” re-named) under Captain Dumont D'Urville. The botanist of this expedition as of the previous was A. Lesson, whose name is perpetuated in the remarkable genus of seaweeds known as Lessonia. The botanical results of this expedition contributed by Lesson and Richards were

published in 1832, and contain 29 species of New Zealand seaweed, of these however 8 were collected by Banks, one by the Forsters of Cook's second expedition, and one by Andrews, so that our knowledge of the seaweeds grew but slowly. The most important discoveries of Lesson and Richard, were the seaweeds placed by them in the genus Marginaria; this still remains one of the most characteristic of the distinctively New Zealand genera. In 1837-40 D'Urville (now admiral) paid a third visit to New Zealand in command of the “Astrolabe” and Zélée and collected largely at Port Ross in the Auckland Islands. The seaweeds are described by Montagne in the Voyage au Pôle Sud, Bot. Crypt. 1845. There are some fifty species enumerated, with excellent illustrations and drawings. In addition to the Auckland Island specimens, a number were obtained from the Bay of Islands and Akaroa. A few months later Sir James Ross in command of the “Erebus” and “Terror” also explored the Auckland and Campbell groups. With him were Dr. J. D. Hooker (afterwards Sir Joseph Hooker) and Dr. Lyall. The seaweeds are described in the first volume of the Flora Antarctica (1845) and shew a large increase in number of species and in accuracy of description, and indeed the Flora Antarctica constitutes a landmark on the road to our present knowledge of the New Zealand marine Algae. The Flora Novae-Zelandieae appeared in 1853-55, and in 1864 Hooker's Handbook of the New Zealand Flora was published, containing short descriptions of all the seaweeds known from these islands up to date. It still remains the only work in England in which the student can obtain a general account of the local species. In it are described some 317 species, Clorophyceae 40; Rhodophyceae 219; Phaeophyceae 58. The work is by Hooker's collaborator, W. H. Harvey, who himself had never visited New Zealand. Considering the circumstances under which it was completed, it may be considered a remarkable achievement, though it is often far from reliable. It includes many Australian species, and some of the descriptions—even for the day in which they were written—do not reach a high standard of accuracy. This makes it impossible for one without type-species to identify a considerable number of Harvey's plants. In the late sixties Baron F. von Mueller sent to Dr. Agardh of Lund a number of specimens of seaweeds collected by Mr. H. H. Travers in the Chathams; a list of these appears in Trans. N.Z. Inst. 6 (1874) 208-210. A fuller account had been published at Stockholm under the date 11th May, 1870; this is particularly valuable for the discriminations of the various species of Cystophora and is the first account of the species from the Chathams. In 1877, Prof. Agardh published a complete list of the New Zealand seaweeds, under the title De Algis Novae Zelandiae marinis. This is based on the collections of Dr. S. Berggren made during the years 1874-75, and is an immense improvement upon Harvey's list, though it includes only 277 species. Agardh excluded about seventy-two species included in the Handbook, and only a few of these have since been restored. Harvey had died before the publication of the Handbook of the New Zealand Flora, and doubtless had the Algae therein been revised by him, the work would have been considerably improved.

In Trans. N.Z. Inst. 32 (1900), I published a “Revised List of the New Zealand Seaweeds Part 1.” This contained the Chlorophyceae and Phaeophyceae. Part 2 of this paper (Florideae) was published in 1902, and an Appendix in 1905, including in all some 419 species. Since that date much work has been done on the seaweeds in general, and a certain amount on the New Zealand species. In 1901, Falkenberg subjected the family Rhodomelaceae to a critical examination, which resulted in a very large number of generic changes. I was unfortunately unable to include these in my previous list of Florideae, consequently the present list of this family bears a very different appearance from my earlier one. Dr. M. Foslie, whose early death is much to be deplored, added largely to our meagre list of Corallines, from specimens received from Dr. Setchell, who had collected some on a visit to New Zealand, and who had also received a few from myself, largely collected at Lyall Bay, Wellington. Of great importance is the Alghe di Australia, Tasmania e Nuova Zelanda (1923) by G. B. De Toni and Achille Forti. This contains the results of collections by the Rev. Doctor Guiseppe Capra in 1908-1909. Dr. Capra visited the Bluff, Port Chalmers, and Lyttelton, and made considerable collections of seaweeds at these places. The work is remarkable for its extensive Bibliography, and for the fact that it is the most up-to-date account we have of the New Zealand species therein described. These number about seventy-five and there are at least twelve new records. Many other investigators have done some work on the New Zealand Algae in recent years. Perhaps I should particularly mention Dr. Cotton of the Cryptogamic Department of the British Museum at Kew. He described the seaweeds collected by Mr. W. R. B. Oliver at the Kermadecs, and has also provided a list of the Chatham Islands Algae. My own list of the Auckland and Campbell Island species was published in The Subantarctic Islands of New Zealand (1909). Though Dr. Skottsberg has not visited New Zealand, his work on the species of southernmost American and the adjacent antarctic lands is very valuable for the New Zealand student. For further details the Bibliography appended to this list should be consulted. Unfortunately in Agardh's De Alg. N.Z. mar. no attempt has been made to refer the species to the original author, and this is true of most of my own lists. Now any New Zealand student who wishes to work at the seaweeds, would first of all have to prepare for himself a list properly dated and authenticated, and for this purpose he would have neither the literature nor the clues to this literature. I have therefore in this paper endeavoured to provide him with a standard reference list, which contains the date, and the name of the authority for each species. Fortunately we have most of the necessary literature in Christchurch, and I have been able to keep sufficiently in touch with algological work, to be sure that not very much of importance has escaped observation. The work of the early voyagers and scientists is to be found in the various Christchurch libraries; and I have in my own library a considerable collection of algological writings, including C. Agardh's Systema Algarum, Turner's Fuci, Kuetzing's Species Algarum, Harvey's Phycologia Australis,

and all the necessary works of J. Agardh. I have included in the Bibliography to this list only works consulted by me, and this will enable the student to ascertain the works on the subject actually existing in New Zealand. Unfortunately, too, we do not possess a set of De Toni's Sylloge Algarum (its present price is more than £100). With it much of the labour involved in completing this paper would have been avoided. Still it is probably no bad thing that I have had to go to original sources in preparing this list. Doubtless some of the literature I should have had was not available; but it is not likely to have been very extensive. I particularly regret, however, that I did not have Dr. Cotton's “Marine Algae from North of New Zealand and the Kermadecs.”* Through the kindness of Dr. Cotton, I have since obtained a copy. This no doubt would have provided some extra species for the list, but I hope to obtain it subsequently. For the classification of the Chlorophyceae, Dr. West's Algae vol. 1 (1916) Cambridge Univ. Press, has chiefly been depended upon; and for the genera outside the green algae, I have largely followed Engler and Prantl's Pflanzenfamilien (1897) Teil. 1, Abteilung 2. Dr. Oltmann's Morphologie und Biologie der Algen (ed. 2) has come to hand too late to be used. Though this reference list is intended to be inclusive rather than critical, no species has been retained that has not passed a close examination by one or more good authorities, and a considerable number have been rejected because it seemed unlikely that they would be re-identified. It is of course possible that some of these will have to be reinstated. Nevertheless the list still contains over five hundred species. The New Zealand Myxophyceae have not been collected, and remain practically unknown. The few that have been noted appear for the sake of completenes in the list. The Bacillariceae have been completely omitted, as I have not studied them. Doubtless, too, there are a considerable number of the smaller brown seaweeds to be collected and described; and there are also many more parasitic species to be found, particularly amongst the Florideae. The list of Corallines has been much increased, but much remains to be done. Many of the reds are still insufficiently defined. In some genera at least the number of species will have to be reduced. Fragments of the same species, shewing in some cases polymorphic differences, have been described as different species. This is true at least in the genera Gigartina, Plocamium, Nitophyllum, and probably in other groups. Algolgists who themselves have not collected the specimens are readily deceived by differences of form due to environment. Plants growing in deep water, still water, in winter, near low tide mark, often being very different in appearance from the same species growing in shallow water, rough water, in summer, or above low tide. This has undoubtedly led to some duplication of the species, particularly in the larger genera, where the describer has not been the collector. In genera like Ulva and Enteromorpha there is still considerable uncertainty as to the limits of the species, even where they are best known; and it is little wonder therefore that there is still much to be done here amongst many of the commoner New Zealand species before their specific rank can be definitely decided. I have endeavoured to make this paper as compact and brief as possible, and have therefore omitted nearly all synonymous names

and details of distribution. I have only given such synonyms as are necessary to connect this list with those immediately preceding it, and I have given only such details of distribution as have not been given in previous papers. For fuller synonymy and for the internal distribution of the species, reference will therefore have to be made to earlier writings. The region included in the paper, lies between the Kermadecs and the Campbell Island and includes the outlying Chatham Islands. An endemic species is therefore one not known outside that area. If only one portion of the area is mentioned then the species is known only within that part. Thus a species marked Chathams (Endemic) is only known from the Chatham Islands. New Zealand means that the species is found in the North or South Island of New Zealand or in both, but not necessarily in the outlying groups. A word or two in conclusion may be said on the commercial value of the seaweeds. There is little doubt but that the vegetable harvests of the sea will become more and more valuable. The Maori used a few species of seaweed as a food, the Japanese cultivate certain species. Different kinds have considerable medicinal value, real or imputed. The use of seaweed has been suggested as a cure for goitre so prevalent in New Zealand. It is already an ingredient in various cough cures. Along our coasts in many places some of the larger fucoids (Macrocystis, but not D'Urvillea) are employed as valuable manures. Other more or less problematical uses have been suggested —e.g. for the manufacture of fuel-spirit and the production of a kind of gelatine. Whatever may be done in the future, we should at least as soon as possible endeavour to obtain some knowledge of the extent and variety of the seaweed-fields along our coasts. Class Myxophyceae.

Setchell (The Scinaia Assemblage p. 96.) doubts the existence of this species in N.Z. “It seems questionable therefore, whether there exists any species of cylindrical unconstricted Scinaia on the Australian or N.Z. Coasts.” The matter must be left in abeyance until there is further opportunity to re-examine the N.Z. specimens. Setchell considers that our plant is probably only a form of Gloiophlaea scinaioides J. Ag. S. furcellata is widely distributed.
