Bulletin of the British Museum (Natural History) Erik Acharius and his influence on English lichenology David J. Galloway Botany series Vol 18 No 2 28 July 1988 The Bulletin of the British Museum (Natural History), instituted in 1949, is issued in four scientific series, Botany, Entomology, Geology (incorporating Mineralogy) and Zoology, and an Historical series. Papers in the Bulletin are primarily the results of research carried out on the unique and ever-growing collections of the Museum, both by the scientific staff of the Museum and by specialists from elsewhere who make use of the Museum's resources. Many of the papers are works of reference that will remain indispensable for years to come. Parts are published at irregular intervals as they become ready, each is complete in itself, available separately, and individually priced. Volumes contain about 300 pages and several volumes may appear within a calendar year. Subscriptions may be placed for one or more of the series on either an Annual or Per Volume basis. Prices vary according to the contents of the individual parts. Orders and enquiries should be sent to: Publications Sales, British Museum (Natural History), Cromwell Road, London SW75BD, England.

At the instigation of Olof Swartz in Stockholm, both Smith and Turner corresponded with Acharius and sent him lichens from Britain, and from British explorations in the Pacific and North America. The influence of Acharius and Swartz on the development of lichenology in England in the early years of the 19th century is here traced through unpublished contemporary correspondence between Acharius and Swartz in Sweden, and Smith and Turner in England. The circumstances surrounding Acharius's important gift of lichens to the Linnean Society of London [now in the herbarium of the British Museum (Natural History)] are described, and a list of the lichens in BM-ACH appended. Introduction The pioneering advances in lichen taxonomy made by Erik Acharius (1757-1819) and recorded in his major published works, Lichenographiae suecicae prodromus (1798), Methodus qua omnes detectos lichenes (1803), Lichenographia universalis (1810), and Synopsis methodica lichenum (1814) were first adopted in England by Dawson Turner (1775-1858) and Sir James Edward Smith (1759-1828). Prior to Acharius's work, the majority of accounts dealing with British lichens (Hudson, 1762, 1778; Withering, 1776; Lightfoot, 1777; Dickson, 1785; Relhan, 1785; Smith, 1790-1814, 1791, 1794; Sibthorp, 1794) followed Linnaeus (1753) in their use of the collective genus Lichen. Laundon's excellent account of William Withering's lichens (Laundon, 1984) gives a good account of British lichenology at this period. In 1803 Acharius broke with Linnaean tradition, and in his Methodus he segregated the old genus Lichen into smaller independent genera, thereby laying the foundations of modern lichen taxonomy (Sernander, 1917; Vitikainen, 1976; Galloway, 1981). Lichen collections examined and annotated by Acharius in the preparation of his major taxonomic works thus have a fundamental importance in many modern taxonomic revisions. Typification and location of Acharian material is discussed by Tibell (1987: 257-259). Acharius, scientifically and geographically isolated in the small Swedish town of Vadstena (Ostergotland), relied mostly on his friend and colleague, Olof Swartz in Stockholm, for the provision of lichen specimens from foreign countries, and it was through Swartz that he first received English lichens from Smith, Turner, Borrer, Harriman, and Winch, as well as lichens Bull. Br. Mus. not. Hist. (Bot.) 18 (2): 149-194 Issued 28 July 1988 150 DAVID J. GALLOWAY collected by Archibald Menzies during his two circumnavigations of 1786-89 and 1791-95 (Galloway & James, 1977; Galloway, 1986; Galloway & Groves, 1987). Olof Swartz (1760 -1818), the leading Swedish botanist of his day, visited England in 1788 on his return from the West Indies (Hooker, 1840; Stearn, 1957; Stafleu, 1971) and, through his fellow countryman Jonas Dryander, he became well acquainted with the Banksian Herbarium and the circle of botanists who routinely used Sir Joseph Banks's great plant collections, scientific contacts which he maintained to his death in 1818. Swartz's correspondence with Menzies began in 1791 after his return to Stockholm (Galloway & James, 1977), and later there followed a protracted correspondence between Swartz, Smith, and Turner on lichenological matters. Subsequently, Swartz encouraged a lichenological correspondence between Acharius, Smith, and Turner, culminating in the election of Acharius to Foreign Membership of the Linnean Society of London and his gift to that Society of a named set of lichens [now in the British Museum (Natural History)] illustrating his taxonomic system first expounded in the Methodus and expanded in Lichenographia universalis. In the present paper, unpublished correspondence between Smith, Turner, and Swartz, and between Acharius, Smith, and Turner, is examined in an attempt to illustrate the impact of Acharius's taxonomic theories on the development of English lichen- ology in the first decade of the 19th century. In addition, the circumstances surrounding the gift of lichens that Acharius made to the Linnean Society are described, also from contemporary correspondence. Notes on sources The Acharius correspondence is held in the University Library, Uppsala, Sweden, and contains three letters from J. E. Smith (G 5a: 77-79) written between 1801 and 1806, and three letters from Dawson Turner (G 5a: 84-86) written in 1806. The Swartz correspondence is held in part in the Gustaf von Brinkmann Collection, Trolle Ljungby Castle, Backaskog, Sweden (copies held in the library of the Royal Swedish Academy of Sciences, Stockholm), and in the Library of the Royal Academy of Sciences, Stockholm, Sweden. In the von Brinkmann collection there are three letters from J. E. Smith (1800-1813), and in the main Swartz collection in the library of the Royal Swedish Academy of Sciences there are nine letters from J. E. Smith (1791-1809), and 18 letters from Dawson Turner (1801-1816). The correspondence of Sir James Edward Smith is held in the Archives of the Linnean Society of London (Dawson, 1934), and contains eight letters from Acharius (1799-1813), and 10 from Swartz (1795-1813). The correspondence of Dawson Turner is held in the library of Trinity College, Cambridge (Dawson, 1961), and contains five letters from Acharius (1804-1813), and 21 letters from Swartz (1802-1818). In the extracts of letters used in this account, spelling is kept as in the original documents. In certain cases an ordering into paragraphs has been made for ease of reading. Editorial comments within quotes from letters are placed in square brackets. Lichenological links between England and Sweden 1791-1804 James Edward Smith, purchaser of the library and collections of Carl von Linne in 1784 and founder of the Linnean Society of London in 1788 (Stearn, 1988; Walker, 1988), first published on lichens in 1791 (Smith, 1791a). As a student in Edinburgh in 1784 he had already lectured on newly discovered lichens in Scotland that were not recorded in Lightfoot's Flora scotica (1777), demonstrating a considerable interest in, and knowledge of this plant group (Galloway, 1979). His correspondence with Swartz began in 1791 in the following manner: 'I am happy that my office in the Linnean Society affords me this opportunity of assuring you of my respect and of expressing at the same time my regret that I was absent from England when you were here. It would have given me the greatest pleasure to have conversed with you on our favourite subject of botany, and to have rendered you any service in my power, especially to have submitted to your inspection those treasures of science which good fortune has thrown in my way, and which I wish to render as useful as I can. My good friend Mr. Afzelius (now in Scotland) has told me that you had expressed a desire of corresponding with me. Nothing will give me more pleasure, as it is the only amends you can make me for not having seen you. I shall be very glad if I may have any ERIK ACHARIUS AND HIS INFLUENCE ON ENGLISH LICHENOLOGY 151 duplicate specimens that may be acceptable to you, and you can doubtless enrich my herbarium very much in return! Permit me however to make one observation, which my natural frankness and love of truth will not allow me to conceal. I could have wished [you] had not said in the preface [to your] Prodromus that you had compared your specimen with the Linnean Herbarium, but rather that you had compared them with those of Sir J. Banks which had been compared with those of Linnaeus. This is a very different thing. As it stands now the world may justly wonder that you have not returned me any thanks, which (allow me to say) I feel conscious I should, if in England, have acted so as to have deserved. The matter may easily be corrected when you publish anything else, and it is better it should be corrected by you than me.' (Smith, 1791ft). In a letter written on 21 May 1792 Smith added: 'I received your letter of 16 July last and, (some time ago) that of November 27. 1 beg your pardon for not answering them sooner, and now I can only give a hasty reply, having been ill, and obliged to go for some time into the country for air. I will not however omit this opportunity of saying I am perfectly satisfied with your explanation on the subject of my last letter, and if you explain the matter as you say, in your next publication it must be quite satisfactory to the public. I shall be happy to merit your future confidence and esteem as much as (I doubt not) you will mine. I would not have you rely too much on specimens named even by Linnaeus himself in his old age. I find he often made mistakes. I trust only to original specimens , which I know by numbers and marks to be what he had before him when he wrote the Species Plantarum. Young Linnaeus's authority is still worse, as he appears to have been oftener wrong than right in naming plants, even when he had the true specimens to compare with.' (Smith, 1792). In May 1794 Smith sent Swartz copies of his papers published in the second volume of the Linnean Society's Transactions and some plants from New Holland (Australia) for Swartz's herbarium. Swartz reciprocated with specimens from his own collections, among them several lichens which drew from Smith the rejoinder: 'I am quite ashamed to find I have not written to you since May llth 1794, but I have many good excuses to give, having last year had very bad health, and having more writing upon my hands than I could well accomplish, I delayed answering your last favour, dated September 10 1795, till I should receive the packet you mention which I now have. I hope also you will have some indulgence for me when I tell you that I am just now married . . . Thank you for the lichens. The discolor agrees perfectly with my saturninus (for I gave Dickson the name and description) except that mine is more villose underneath. Yet I think they are one species. Your Lichen crassus Huds. , is right, and very near my chrysoleucus , yet the latter is more foliaceous, and the scutellae larger and yellower. I shall examine carefully if they be distinct or not. L. hyperboreus I thought, at first sight, the torrefactus of Lightfoot, but it is very distinct, especially the under side. The beautiful L. erosus is also near torrefactus, but I think distinct. L. pellitus is certainly polyrrhizos of Lightfoot, and velleus of Hudson; Linnaeus confounded it with his velleus which it is not. L. griseus is exactly the same as my plant gathered at Ermenonville (see Tour Vol. 1. 104), which I presume to be Vaillant's t. 21.f.l4; but upon the most careful reexamination, I fear it is not the real deustus of Herb. Linn., marked No. 970 of Fl. Suec. ad. 1. which is therefore an original specimen, and which is said to be so common in Uplandia. You I presume know this lichen. The Linnean specimen is in fructification. Can you send me more of it? What you have sent for deustus may be the same, but your specimens are larger and more dilated than the solitary one in H.L. The scutellae are similar. What you have sent for polyrrhizos Dill. , and the English writers (and which you say is sometimes coarsely hairy beneath) is not so, nor can I tell what it is. It is the colour of the true vellus H.L. , and Dill. tab. 82.f.5, but that is very hairy beneath. Can it be that? L. hirsutus Act. Holm, is certainly Dill. fig. 117, as I have seen at Oxford, and I have it in H.L. marked polyrrhizos, but in Ehrhart's writing, consequently no original authority. Yet I know nothing else that can be polyrrhizos Linn. From what I have seen in Switzerland I suspect this and the true velleus may be varieties of each other. I will shew Dickson your Lichen membranaceus when I see him next and tell you what he says. Dr. Acharius appears to be (as you say) a most accurate botanist. Your countrymen are (without any compliment) the most acute of all people. Your observations on my paper on Wulfen's lichens are, I dare say, very just. I shall profit of them when I have an opportunity ... I cannot find the promised Lichen Westringii among those you favoured me with . . . You ask for Lichen exasperatus Lightf. What is it?' (Smith, 1796a). 152 DAVID J. GALLOWAY The discussion between Smith and Swartz on the Swedish lichens sent to London continued six months later: 'I now sit down to answer your letter of June 6 ... Never make any apology for enquiring or asking me for any thing in my power. I wish to be useful to those who really promote science, and shall always be happy to serve you. I send you such a morsel as I could take off from Linnaeus's original little specimens of Bryum vividulum - it is quite different from any of those enclosed in your letter . . . As to Lichen polyrrhizos of our English writers which is Dill. t.30.f.!30, you may be positively assured it is exactly the same as Lichen pellitus of Acharius which you sent me. I have no English specimen at hand to spare, or I would send it to you, but you have no occasion for it. I have one specimen from Scotland in fructification, which is very much convoluted like a Madrepora labarynthiformis (I think it is called), as in the figure in your Acta. I am very sorry I cannot find a bit of Lichen torrefactus to send you now, but I think I have some among my Scotch plants somewhere - when I find it you shall have it. It seems to me much more foliaceous and complicated beneath than L. hyperboreus Acharii, which is quite simple ... I shall be extremely obliged to you at any time for any new or rare Cryptogamia, especially such as are described in your Stockholm Transactions. I long to receive the continuation of that work . . . Your Lichen erosus is very distinct from Lightfoot's torrefactus. Whatever Schrader's may be ... Our Linnean Society flourishes much, as you will see by the list enclosed ... I am going to reside at Norwich where all my relations live, and where I hope to be more master of my time than I can be here. I can be in London at any time in 15 hours, and I shall spend some months there every winter. I shall also continue my lectures at Guy's Hospital . . . Please to observe my name is James Edward, it is printed by mistake John in the Stockholm Trans. I had called this New Holland plant Acharia, but finding Professor Thunberg has one of that name in his Prodromus, I have changed mine to Westringia; Mr. Westring seems by his paper highly deserving. Pray express the title of his dissertation properly in my paper - 1 did not know well how to do it. I am the author of Sowerby's English Botany entirely - and have put my name to the fourth volume - it sells very much . . . Adieu my good friend - let me hear from you soon ... I am preparing a Florula of New South Wales.' (Smith, 1796b). On 18 July 1799 Acharius first wrote (in Latin) to Smith offering him a copy of his Lichenog- raphiae suecicae prodromus for the Linnean Society Library (Figs 1, 2). On 10 February 1800 Smith wrote to Swartz: 'I have not yet received a work of Mr. Acharius on Lichens which he sent long ago by Hamburg I believe ... I have several fasciculi of Sowerby's Fungi to send you when the season of the year will admit. I have been of late a very negligent correspondent to you and many other friends, because I have worked so hard at my Flora Britannica, and have had too much writing on my hands besides other business. My flora is now printed as far as Monoecia (Carex) and I am busy writing the Cryptogamia. You perhaps have not heard of another much greater (though perhaps not more difficult) work I have lately undertaken, the Flora Graeca. All Dr. Sibthorp's collection of specimens and near 1000 very fine drawings are put into my hands by his executors and the University of Oxford. I am to make the descriptions, fix the names, and digest the information contained in his Journal. The work will consist of 10 folio volumes of 100 coloured plates each, in the style of Jacquin's Flora Austriaca, but much better done. There is also to be a Prodromus in 8vo. The drawings are so very fine we can hardly find artists to colour the plates well enough to be compared with them. I received very safe your letter of October 1798 and a valuable parcel of Cryptogamia, particularly useful to me just now . . . I could not have thought before I began, there had been so much to do in the Flora Britannica. ... I wish my Fl. Brit, may not disappoint you. If I had none but such partial and intelligent friends as you to judge it, I should not be so afraid, because you would know the difficulties I had to surmount.' (Smith, 1800a). Upon the arrival in Norwich of Acharius's work on Swedish lichens Smith wrote to Swartz: 'I shall be greatly obliged to you for specimens of your new discoveries - especially in the Cryptogamia. I long for Lichen Dillenianus of Acharius. Will you be so good as to inform Dr. Acharius that I have received his most excellent book, though a long while (almost a year I believe) after his letter, and having of late been much from home, I have had but little time to study his work. I therefore postpone writing to him till I can collect all the queries and remarks I have to offer, as well as make out a list of my desiderata. I shall then communicate to him in form the thanks of the ERIK ACHARIUS AND HIS INFLUENCE ON ENGLISH LICHENOLOGY 153 »' / , '/in i/\ i- f srnf* t*<*rr*/J, .ffir/rti't-J m SYKCICAE AUCTOR u? u i \ r hrrk ,:Vh; ,:,:' A', vv.', •• /tV,/ Jl:.,'i)/»v.-, .!'.•«/ V. -. ./.-,.,y. ,»,'•', . .*'-,,. i- j'.v.v'. /;.-/ „-.-,/ Liucopiac ;l)i\.Bjoni; i Fig. 1 Title page of Lichenographiae suecicae prodromus (Acharius, 1798).

In the meantime beg him to accept of my best thanks, and assurances of sincerest esteem ... I shall take the liberty of having Dr. Acharius proposed as a foreign member of our Linnean Society. Perhaps Mr. Westring too would like to be a member - my compliments to him . ' (Smith , 1800ft) . In reply Swartz wrote to Smith: The honour you would confer upon Mr Acharius and Westring in proposing them as members of the Linnean Society, they certainly would esteem very highly; and I dare say you cannot propose worthier men. Both are, as you know, pupils of Linnaeus and of well know ability.' (Swartz, 1801o). 154 DAVID J. GALLOWAY LICHENOGRAPHIAE • Fig. 2 Acharius's dedication to J. E. Smith on the fly leaf of Lichenographiae . . . Library, Linnean Society of London. In 1800, Dawson Turner, who had become interested in lichens after reading Acharius's Lichenographiae suecicae prodromus sent a letter to Acharius through J. E. Smith, but because of political difficulties existing between Britain and Sweden at that time, normal correspondence between the two countries was not able to be resumed until one year later. Turner began his correspondence with Swartz: 'It is now almost a year since, attracted by Dr Acharius's valuable publication upon the lichens, I ERIK ACHARIUS AND HIS INFLUENCE ON ENGLISH LICHENOLOGY 155 took the liberty of addressing to him a letter, which I entrusted to our mutual friend, Dr Smith, and I am concerned to find that from the compleasant [sic] situation of public affairs between our two kingdoms, he was not able to forward it till a few weeks ago. I also consulted him upon the propriety of troubling you with a letter, and, emboldened by his assurance that you will not consider my so doing as a piece of impertinence, I venture to write to you for the purpose of proposing, if it be not disagreeable to you, occasionally to interchange our sentiments upon Botanical subjects, and supply each other with the vegetable productions of our separate countries. I am well aware that, in making such a proposition, I have very little indeed to offer compared with what I may hope to receive from your liberality; but, being urged by an unbounded zeal for the promotion of our favourite science, and being in correspondence as well with almost all the celebrated British Botanists, as with Dr Schreber, Dr Roth, Dr Schrader, and Dr Esper in Germany, I would fain flatter myself that, like the mouse with the lion in the fable, I may be able occasionally to render you some service. My studies have of late been principally directed to the Musci and Algae, among the latter of which, especially the Fuci, Ulvae, and Confervae, my collection is very extensive, and I shall have infinite pleasure in supplying you with any that may be wanting to your herbarium. Of lichens and mosses I can offer you almost all the British species, but I have hitherto had very little opportunity of acquiring any not natives of this Island, and shall be particularly thankful for whatever specimens you can spare of Swedish or American Lichens, or of the mosses described in your beautiful little publication ... I shall now add no more, except that, if my proposal be not unpleasant to you, and if you will have the goodness to send me a parcel of any, not gathered in Britain, of submerged algae, Lichens, Jungermanniae, or Mosses (no matter how common, for all plants natives of distant countries have slight shades of difference from soil, climate etc) addressed to the care of our friends, Sir Joseph Banks, or Dr Smith, and will at the same time favour me with a letter by post containing a list of your desiderata, and mentioning how I can most effectually serve you, it will give me exceeding pleasure to take every opportunity in my power of having the respect I entertain for so deservedly eminent a naturalist, and the high esteem with which I now have the honour of subscribing myself.' (Turner, 1801). In November 1801, Swartz sent notice to Smith: 'I intend with these lines to inform you that I have just sent of [sic] for England to the care of Sir Joseph Banks and Mr Dryander, two parcels containing the one some specimens of Lichens from Dr Acharius, to which I have put some few, that he could not afford.' (Swartz, In December of the same year Smith wrote (in Latin) to Acharius, sending a collection of lichens, and outlining his own manuscript diagnoses of those he considered new. Among these were five lichens collected by Archibald Menzies from New Year's Harbour, Staten Land, and from British Columbia in 1787 while he was surgeon on Captain Colnett's ship, the Prince of Wales. Smith described Menzies' newly discovered lichens thus: '205 Lichen intestinalis MSS [= Hypogymnia enter omorpha (Ach.)

ERIK ACHARIUS AND HIS INFLUENCE ON ENGLISH LICHENOLOGY 157 (1803), including Smith's incorrect designation of Staten Land as 'Ad Fretum Magellanicum', an error which has been a source of confusion to later authors attempting to typify Acharian taxa with Menzies' specimens (see J0rgensen, 1975; Galloway, 1986). After receiving his first parcel of lichens from Sweden, Smith wrote to Swartz: 'How can I sufficiently thank you, my dear friend, for your favours to me? This week Sir Joseph Banks has sent me your's and Dr. Acharius's most valuable parcels, and although I have as yet not had time to study a quarter of their contents, I will not wait one post day to thank you for them . . . My last letter to you was on the 16th of August last, in answer to yours of February 2, accompanying two fasciculi of Sowerby's Fungi . . . Also a parcel of Lichens for Dr. Acharius, upon which I anxiously wait for his opinion. The packet was entrusted to Dryander to forward to Sweden. I have never heard any thing of the letter or packet of Cryptogamia you sent me by 2 American gentlemen! So much the worse for me! . . . A word or two on Lichens. What you have now sent me as Urceolaria gibbosa I formerly had from you by the name of "L. cinereus versus Linnaei" and you desired me to observe the black margin of the crust, mentioned in Sp. PI. Nevertheless, I presume the cinereus of Acharius, p. 32, is different from his gibbosus, and may be the same as his multipunctatus , which I have taken for the true cinereus in Engl.

I will, as the spring advances, send him a few things that I hope may be acceptable. I wrote him a letter lately full of differentiae specificae of new Lichens (as I supposed), I shall not write again till I have examined his specimens thoroughly. In the meantime I beg you to tell him I find his lepadinus is my inclusus*, Engl. Bot. t. 678, as I guessed. The little morsel he sent marked "L. pallescens versus Linn." is precisely what I have found in Wales, and have sent him (No 7), and which I take from the figure and description in Jacq. Collectanea, to be albo-flavescens of Wulfen. What Acharius sends me as his own pallescens, I think a different species, and more akin (as he says) toparellus and upsaliensis. The true Linnean L. calcareus from the walls of Upsal. , is very near (if not the same) to my tessellatus Engl. Bot. v. 8. t. 533. [Fig. 5] Mine only is rather larger in all its parts. But I shall give them a more careful examination hereafter. My Lichen inquinans, Engl. Bot. v. 12. t. 810. 1 find to be his clavellus, p. 83, but I doubt some of the synonyms, especially Dill. 1. 14. f. 3. His dispersus is exactly the crenulatus of Dickson, which the latter has not well described in his Fasciculi: The 4th fasciculus of Dickson is just published. It contains many new things, but has some inaccuracies, as all such works must have. I am now busy in finally settling the Musci and Lichenes of Flora Britannica, and your specimens are doubly valuable to me ... I will send you and Dr. Acharius something this spring.' (Smith, 1802). Dawson Turner too had received an answer from Swartz and a share in the parcel of lichens posted to Banks. In reply he wrote: 'I received with particular pleasure, and felt myself much honored [sic] by your obliging letter, which, however, I deferred answering till the parcel you were so good as to destine for me arrived, and my patience, never very great, was well nigh quite exhausted, when the kindness of Sir Jos. Banks forwarded it to me a few days ago. You may judge of the eagerness with which I opened it, and I assure you that my expectations were not small, but they were far surpassed by the riches that I found, and I cannot sufficiently thank you for the immense addition that you have made to my herbarium . . . As for British Mosses, I believe I shall be able to send the greater part of your desiderata, but you, who have been in this country, know that these plants are almost exclusively in the hands of Mr Dickson, who dispenses them very sparingly, and gives, to use his own expression, specimens "only just good enough to swear by". As I live in the most level part of England where but few of them are found, this must be my apology, if I should be unable to furnish all you want, or if my specimens should be indifferent. In Lichens I trust I shall prove myself not an unworthy correspondent, and I must by the favour of you, as soon as you have leisure, to send me as many of your Swedish and Indian species, as you can conveniently spare from your more deserving friends.' (Turner, 1802a). Shortly afterwards Turner sent Swartz a first parcel of English lichens noting: '. . . many of the inclosed Lichens are common, but will serve to ascertain what English authors have intended, and, if you do not object, I would propose to you to exchange every species of this * see Bailey & James (1977). 158 DAVID J.

I have marked 6 with numbers, and upon these I beg your opinion.' (Turner, 18026). In his reply to Turner, Swartz wrote: 'Acharius works now upon a general synopsis of the Lichens which will be good . . .' (Swartz, 1802a). A few days later he wrote to Smith: 'Acharius is now working on his new opusculum upon the Lichen tribe. He goes on upon quite a new principle and I think it will do him honour. We have lately had a consulta [sic] in order to settle a number of undetermined points. It will be printed very soon I hope. He rejoiced greatly by getting your last favour.' (Swartz, 18026). Turner had by now begun writing long and informative letters to Swartz about the progress of botany in England, as well as keeping up a lively lichenological dialogue: 'I trust there is not the least doubt of your having received long before this time not only the parcel which I sent thro' the medium of Mr Dryander, but also the copy of my Synopsis, which, on the 31 May, I consigned to the care of our London merchant, who promised to forward it to you by the earliest opportunity. I fully intended to have sent you some more plants at the same time with the book, and also to have thanked you for your friendly letter of the 13 April, but I was called upon for it sooner than I expected, and since then have hardly had a single moment to myself, for in the beginning of June I set out from Yarmouth, proceeding as fast as I could to Ireland, where I stayed 16 days, examining the environs of Dublin, and afterwards returned thro' Angelsea and North Wales, so that I am but just home again. I had expected great botanical treasures in Ireland, and had purposed penetrating into the southern part of that little explored Island, but various events contributed to disappoint me, for my time was short; travelling in Ireland is very tedious; and above all, Dr Scott, Professor of Botany in ERIK ACHARIUS AND HIS INFLUENCE ON ENGLISH LICHENOLOGY 159 Dublin, at whose house I visited, and who was to have accompanied me, was in such indifferent health that he was unable to undertake the journey, and persuaded me to continue in the metropolis. On these accounts this part of my tour was very unproductive in point of natural history, but, from what little I saw in the environs of Dublin, I am convinced that the muscologia of Ireland would, if examined by a botanist as skilful and accurate as you are, bid fair to rival yours of Sweden and Lapland, such continual rain falls in every part of the country, and it is composed of such a series of old woods, rocky mountains, lakes, and dep dells. I gathered at one place several species, among which I expect to find one or two nondescripts, but at present I have not had time to look at any. When I have, you may depend upon it that I will carefully lay by for you whatever is worth your acceptance. The Botanic Garden at Glasnevin, near Dublin, far exceeds in magnificence anything of the kind in Britain. It contains 27 English acres, besides a fine house for the Professor (who has a salary of £300 per annum and an additional £100 for travelling expenses) and 5 hothouses and greenhouses, about 60 feet long, 23 wide, and 25 high. At present however it is only in its infancy, and not well filled, but the gardener, Mr Underwood, is a pupil of the late Mr Curtis', and bids fair to bring it to great perfection. In Wales I was more fortunate in point of botany, but terribly unlucky as to weather, for when I climbed the famous mountain, called Snowdon, the highest in the principality, I was above half the way so immersed in the clouds, that I could see nothing on either side of me. I nevertheless brought home a pretty good collection of many British Alpine plants, and, what was of more consequence, confirmed my acquaintance with Rev. Hugh Davies, and Mr Griffith, so that I shall have no difficulty in hereafter procuring any of the productions of that country. I have written thus much entirely about myself, not only under the hope that the subject will be interesting to you, but to shew that I wish you to do the same in return, and I therefore hope you will regard it as an example, by acquainting me with any excursions you make, or any particulars of the natural history etc of your country . . . I am about to apply myself closely to the Ulvae and Lichens, under the hopes that I may possibly at some future day write a Lichenographia Britannica. My Ulvographia, I trust, will be ready next year, with figures of every known species. Would it be possible for me to obtain the honour of admission into your celebrated Academy? I ask as a stranger and as one who is aware that he has little claim to such a distinction. Pray do not fail to let me hear from you immediately.' (Turner, 1802c). Swartz replied warmly to Turner: 'You have obliged me very much by the communication of the Scientifical News. I am very glad to receive them. We are by far not so productive in this corner. My friend Acharius works upon his Lichenographia, which I dare say will afford [a] good deal of amusing instruction to the reader. It is to be printed soon and contains everything that has come to the knowledge of the indefatigible observer.' (Swartz, 1802J). The same day Swartz wrote also to Smith informing him: 'Acharius works upon his Lichenographia, and I think the printing will begin soon. He has told me to be very anxious to get some information from specimens you may perhaps have promised him. This work will be very good.' (Swartz, 1802d). The following month (October) Swartz sent to Smith a further parcel of lichens with the message: 'some lichens and some other plants . . . you'll find also a pack from our friend Acharius . . . Acharius is sorry that he did not get before winter what you had sent him. Probably it is in London still remaining. His Methodus Lichenum is now printing. A very good work indeed.' (Swartz, 1802e). Meanwhile the parcel of lichens that Dawson Turner had sent to Sweden earlier in the year had not reached its destination, a circumstance Turner regretted in a letter to Swartz: The pleasure, which your obliging letter of the 10th September gave me, was, I am sorry to say, sadly damped by the information that neither the parcel I sent to you through the medium of Mr Dryander on the 12th April, nor the copy of my Synopsis, which I afterwards trusted for you to a London Merchant, had yet reached your hands. The loss of the latter would be of no consequence, as I can immediately replace it, and will do so with great pleasure, if it have not yet found you: about the parcel I must own I feel anxious, for it contained most of my rarest British Fuci, several lichens, among which were some from Dickson himself ... I am therefore fearful that its non arrival may cause you some inconvenience. It contained likewise a letter, proposing you to exchange every 160 DAVID J.

My Ulvographia occupies me, but I still think of a general Fucologia, and a Lichenographia Britannica.' (Turner, 1802d). The publication of Methodus qua omnes detectos lichenes (Acharius, 1803) (Figs 6, 7) was first intimated to Smith by Acharius in a letter dated 28 April 1803 (Acharius, 1803b), and in a letter from Swartz shortly after: ERIK ACHARIUS AND HIS INFLUENCE ON ENGLISH LICHENOLOGY 161 .-. -.. / /- ^.V^-. <~ •* •» *-*•».- ***, ;r/:A /,£_„...,. .

May it have a better fate than the sendings last year which appear to be lost! This new unhappy War I am afraid will occasion new impediments for our literary intercourse. If I am happy to receive anything from you I shall inform you directly as Dr Acharius undoubtedly also will do. His Methodus Lichenum is already printed, and I have at his desire sent you and Sir Joseph Banks a copy within these three weeks by a countryman who may at present be arrived in London. Please to ask for your parcel at Sir Jos. Banks's. The Supplement is still wanting, it is printing actually at Liepzig, and you may probably have it in the Autumn.' (Swartz, 1803a) (Fig. 8). Turner, who was preparing a paper on some new lichens for the Linnean Society's Transactions (Turner, 1803« , 1804a) wrote about this to Swartz: 'What would I not give were you near enough to inspect and correct my manuscript? I have no friend in England who is able to do me such an office, and for want of this, I am but too certain I shall fall into many errors. I presume from your letter that Dr Acharius has already published his Methodus Lichenum, and I hope therefore that before many months our booksellers will have imported it. I shall look forward to the receipt of it with much eagerness, for the Lichens are so very favourite a tribe with me, and I am never without hopes of one day writing myself a Lichenographia after which I shall consider myself "donatum jam sude".' (Turner, 18036). In response to Turner's second parcel of lichens to replace the first that had not reached Sweden, Swartz replied: To my particular satisfaction I found even in the same parcel an excellent heap of Lichens, by which I have got a good deal of instruction. But in order to give you a more adequate opinion about them, I communicated them instantly with my friend Dr Acharius; whose knowledge of this tribe is 162 DAVID J.

He has lately published his new Methodus Lichenum in which he has himself by this communication detected some errors. You may probably desire to enter upon an epistolary interchange with him, as well in behalf of particular specimens, as an account of various elucidations, which he certainly might be able to give. In the mean time he begs to be remembered to you. If you write to him, the letters may be addressed by the way of Hamburg or Gottenburg to - Professor Dr E. Acharius. Wadstena. Sweden.' (Swartz, 18036). ERIK ACHARIUS AND HIS INFLUENCE ON ENGLISH LICHENOLOGY 163 Because of difficulties in the passage of mail between Britain and Sweden, Dawson Turner did not receive Swartz's letter for eight months. Meanwhile he wrote to Swartz: 'I must thank you for endeavouring to get me some lichens from Dr Acharius. I should be glad if you would ask that gentleman whether he ever received a letter I wrote him 3 or 4 years ago, and inclosed in a parcel from Dr Smith. I have often thought it unhandsome that he did not answer it, but, from something I lately heard, I suspect it never reached him . . . I am sorry I am not able to say anything about the opinions you were so good as to give me of the Lichens I sent, as I have not yet been able to get Dr Acharius' Dispositio. I believe there are but two copies in England, one Dr Smith has, which he will lend me as soon as I am ready to use it, another Mr Winch of Newcastle writes me that he has. I hope soon to receive from you a parcel of Lichens, for I am exceedingly fond of the genus; and I doubt not but by the time they arrive my bookseller will have procured me the work. Dr Smith is quite well; his third vol. will be published in a few days, after which he immediately applies to the Flora Graeca. Mr Lambert's splendid monograph of the Genus Pinus has appeared, but I have not yet seen it. I understand a coloured copy costs 40 guineas, which is a most absurd price. Sir Jos. Banks has been very ill with the gout, but I had a letter from him a few days since, in which he says he is better. He is going to adopt a milk diet, from which, if his constitution will support the change, he promises himself great benefit. I hope God will prolong a life, so interesting to all science, and to all the civilised world ... It would give me great oleasure to enter into a literary correspondence with Dr Acharius, which I would thank you to tell him, and give him my address. All is quiet in England, and at this time but little afraid of Invasion. Should the French come, they will find things more prepared to receive them than they expect.' (Turner, 18046). In May 1804 Turner wrote again to Swartz: 'It is such an age since I had the pleasure of receiving a single line from you, that I cannot help feeling myself both surprized and vexed; nor can I avoid entertaining apprehensions lest some illness or unpleasant occurrence should have caused your unusual silence. I trust you have long since received a letter, which I wrote you on the 2nd February, and upon the proper arrival of which I should not entertain the least doubts, had I not by the same mail written to my friend, Mertens, from whom also I have yet received no answer. In case that letter miscarried, pray have the goodness to let me know; for it contained some information on the subject of Mosses, which I wish not to be lost, and which I would send again at some future opportunity: it thanked you too for your offer of introducing me to your friend, Dr Acharius, and said how happy I should be to enjoy the correspondence of so able a Botanist. From the unfortunate interruption to our communication with Germany, occasioned by the stoppage of the Elbe, his Methodus has not yet found its way to our English booksellers, nor have I had any opportunity of examining it, but Dr Smith, who went to London two days ago, has just sent me his copy to keep during his absence, so that I promise myself in a day or two a rich botanical treat . . . The first part of the Flora Graeca may now very soon be expected; and a new work, to be edited by Mr Konig who lives with Sir Joseph Banks, to be called Annals of Botany, and to appear quarterly: it will much resemble Dr Schrader's Journal . . . Can you favour me in your next letter with specimens of Lichen sylvaticus in fruit, sarmentosus with shields, arcticus, muricatus, and divergensl My desiderata from Acharius's Methodus are numberless, but I have many species which he has not included. I hope however, many weeks will not pass before I receive from you a large parcel of your Lichens, especially the crustaceous kinds. I mean to go to Wales in June, and then shall to be able to repay you.' (Turner, 1804c). Shortly afterwards, Swartz was able to assure Turner of Acharius's willingness to correspond with him: 'Dr Acharius will also estimate himself happy of your acquaintance, and would have written long since if not a domestic calamity had befallen him, poor friend he lately lost him a kind wife! I now write to him to salute him on your part. He never got any letters from you. In the copy of his Methodus which you got from Dr Smith the supplement I suppose is still wanting. It was afterwards printed in Liepzig, and could accordingly not be sent at the same time. It contains mostly new species discovered by Wahlenberg.' (Swartz, 1804o). Acharius's Methodus and its reception in England 1804-1806 At the time of publication of the Methodus, Smith and Turner were among the most active lichenologists in England and both, using Swartz as a catalyst, had established a correspondence 164 DAVID J. GALLOWAY with Acharius at Vadstena, regularly sending him specimens. Smith, the more conservative lichenologist of the two (he never completely dissociated himself from the use of the genus Lichen), first received Acharius's book and wrote to its author on 24 April 1804: 'Dr. Swartz tells me you understand English perfectly* and therefore I shall indulge my indolence in writing in my own language, only requesting you to continue to write in Latin if you please. I am in your debt for three very kind letters dated 8 December 1802, 28 April and 12 November 1803 [this last is not preserved in the Smith correspondence in the Linnean Society of London's archives]. I have also received a valuable parcel of lichens and Mosses, as mentioned in your first letter. For all these, as well as for your Methodus Lichenum, which I have eagerly studied, accept my best thanks. I am very sorry my first parcel did not reach you. The times are unfavourable for communication. There were not (however) any South Sea plants in that parcel, only European Lichens - and I am glad you received my second parcel, which was of more consequence. I beg leave to make a few remarks in reply to yours upon my specimens. In the parcel I am now preparing for you I enclose more specimens of Lichen conspurcatus Engl. Bot. t. 964. 1 think they will prove it be of a distinct species of Lecidea. I have traced its scutellae through their whole growth and they are quite distinct from my corpora parasitica. I beg however, you will never pay any regard to my opinion in this or other matters than you find it deserves. Correct me freely when I deserve it. Lichen duplicatus I cannot help thinking very distinct from physodes [Fig. 9]. Mr. Menzies thinks it indeed may be a variety of enteromorpha, of which I now send you a good specimen. Pray observe the scutellae turbinatae . . . I write this letter a day or two before my departure for London and shall take with me a parcel for you containing some New Holland specimens, which I hope will please you and a very few new or curious Lichens, on which I beg your opinion. I shall also send you the 3rd volume of my Flora Britannica. Do you want the first and second? In my 4th volume I shall profit much by your learned S3» PARMELIA.

ERIK ACHARIUS AND HIS INFLUENCE ON ENGLISH LICHENOLOGY 165 remarks on Lichens, but do not blame me if my opinion on speculative points differs sometimes from yours. Neither dare I change names so freely as you have done. I must keep in view those Laws of Linnaeus which are sanctioned by experience and founded in justice. If you and I do not follow his good principles how can we call others to account? The great Hedwig shall never lead me to use the unnecessary word sporangium for capsule. It is easy enough to invent new words. Genius appears best in using old ones properly. I dare not change Umbilicaria for Gyrophora though I should have preferred the latter at first. I beg to observe that Lichen pustulatus is a true Gryophora. I regret that there should be a word in your excellent book that I cannot zealously defend as a friend ought: but I know we cannot all think alike in philosophy any more than in religion . . . I will propose to the Linnean Society to exchange Their Transactions for something you send. The Linnean Society will be very thankful for any manuscript dissertation of yours for their Transactions. Thank you for your kind enquiries - my health is now restored I had a long illness.' (Smith, 1804). Dawson Turner, more highly enthused by Acharius's new work than Smith, wrote to Swartz: 'I have just been fortunate enough to procure for myself a copy of Dr Acharius's Methodus, and have been arranging the greatest part of my Lichens by it. I agree in great measure with his distribution of the genera, and his remarks as to many of the species have very much pleased me. He is however frequently mistaken about the British Lichens, as I shall be happy to convince him, if he will enter into a correspondence with me. You will probably have the goodness to furnish him with my direction, and tell him I shall be much pleased to be favoured with a letter from him, indeed I would write myself but in his present domestic affliction I too justly fear it might be deemed an intrusion. Pray can the papers he has published in your Nov. Acta be procured? Of these I have the 15th, 16th and 17th volumes; all the 18th except the Numbers for July, August and September; and all the 20th except the last number: could you procure me the rest of Dr Acharius's papers, I would repay the expense involved with a great many thanks. I see by his Methodus that I want all your West Indian Lichens, but on the other hand I possess a considerable number that he has not included, and should I, which I still hope, be fortunate enough to obtain Dickson's collection, I shall be rich indeed in new ones. Even if I fail in this expectation, I am sure Sir Jos. Banks will supply me with all that may arrive hereafter. I am ignorant how readily English books find their way to Stockholm; but I trust if any Botanical publications that would interest you, should appear here, and you be at a loss to procure them, you will never hesitate to apply to me, but be assured that the making me useful to you is one of the greatest kindnesses you can confer.' (Turner, 1804d). Swartz, writing to Turner on the same day as the preceding letter, answered a number of Turner's queries: 'Besides some species of mosses there is also a letter from Prof. Acharius, who salutes you most earnestly and wishes your future acquaintance. He certainly can provide you with some that are out of my reach. He works constantly on the further accomplishing of his Methodus - that he sometimes has been mistaken in regard to English species he knows very well, but this he will acknowledge and correct in future. (Swartz, 1804ft). That Acharius had a strong advocate for his taxonomic views in Dawson Turner can be seen from extracts from the latter 's publications dating from this time, and in the following letter to Swartz: 'I cannot tell you how much pleasure I have received from your letter of the 14th December, [not preserved in the Turner correspondence in Trinity College Library, Cambridge] which has just reached my hands, and which I hasten immediately to answer, wishing very much that the correspondence between us should grow far more frequent than it has even hitherto been . . . I particularly lament the detention of Dr Acharius' letter, and wish it had been sent by post, for I am anxious to have a communication with him: especially as I am about to describe several new Lichens for our Linnean Society, and have been particularly attracted to these plants lately. I am very much pleased with the outline of his new Genera, but there are parts I wish altered, and also I regret his having used so much Greek, for we in England we are not scholars enough to comprehend the meaning of his names of them and certainly far from evcpwvoi. At the request of Mr Konig I wrote a hasty critique upon his Methodus for the second number of the Annals of Botany.' (Turner, 1805). Although Konig & Sims (1804) presented a synopsis of the Methodus in their literature review, it was left to Turner (18046) to publish the first considered examination of the work in an English 166 DAVID J. GALLOWAY journal, and a most thoughtful and enlightening account it is. While convinced of the necessity of employing generic units of a more closely defined character than the old collective genus Lichen, Turner was not slow to offer constructive criticism of the taxonomic system devised by Acharius, and some of his remarks may be recorded here: 'In our opinion, which however we give with becoming diffidence, Dr. Acharius has by this new distribution done no small service to this department of botany; but whether all the genera he has adopted will stand the test of future inquiry, and whether all the species will be allowed to retain the places he has assigned to them, we have already expressed our doubts. It is always to be feared that the author of any system may adhere to his own principles so closely as to lose sight of nature, and thereby cause confusion. With regard, however, to the changing of specific names, we cannot consider him altogether blameless; and we wish we could bring him and some other eminent botanists to our opinion, that nothing tends so much to involve the science in chaos, and nothing is so unworthy of a real naturalist. Indeed, it is the common trick of every pretender to science, who has no other means of rendering himself conspicuous. We could wish too, that, in forming new names, the author had availed himself less of his Greek learning. In short, however we may differ in opinion on trifling matters, we here take leave of what we consider the most excellent work we ever read upon the Lichens, and earnestly recommend it to those among our readers whose attention has been directed to this interesting tribe, wishing Dr. Acharius health and leisure, to continue to throw light upon their physiology and history.' (Turner, 18046). Of Turner's review Swartz wrote two years later: '. . . the review of Dr Acharius's Methodus I have communicated to him. He writes to me, that he finds several remarks well-founded, and that he has already in many instances adopted the same ideas. The number of his species is greatly increased since the publication of his Methodus, from the frequent communication of his friends throughout Europe. This will also enable him to render his work more complete in future. He has separated from the Opegraphae (in my opinion very judiciously) several species, which will form a different genus, called as I believe Arthorica [sic]. The genus Baeomyces will also be differently arranged.' (Swartz, 18060). The first descriptions of British lichens using Acharius's new taxonomic arrangement were made by Dawson Turner and, in an interesting preface to his species novae, he commented upon the relevance of Acharius's work to English lichenology in the following manner: '. . . Methodus Lichenum, a work which may in my opinion be regarded as tending most essentially to facilitate the study of this obscure, yet beautiful and interesting tribe of vegetables, as laying the foundation for enabling us to prosecute the investigation of them upon solid principles, and as having thrown more light upon their real nature and physiology, than could reasonably be expected in the present imperfect state of our acquaintance with the subject. The genera established by this able author are already almost universally received among the botanists of neighbouring countries; and it is with peculiar satisfaction that, convinced myself by experience of their excellence as well as of the necessity of employing them, I avail myself of an opportunity of directing towards them the attention of the naturalists of Britain. It is by no means my intention here to enter into an enumeration of the various attempts which had previously been made to subdivide the vast tribe of Lichens, or even to offer any observations upon the Acharian system, further than may be called forth by the particular individuals which I am about to describe. Such enquiries, however interesting to myself, would lead me into a field far too wide for my present object; and, as in describing the plants themselves I shall have occasion to give the definitions of the genera to which they belong, I will merely add, that I trust I shall not be accused of presumption or of an idle itch for innovation, in being the first who ventures to use in Britain a new arrangement of these plants. No one is more deeply impressed with a sense of the necessity of rigidly abstaining from all useless alteration of names, or multiplication of synonymy. Our botanical nomenclature is already so extensive and intricate as to be perplexing to all, even to those most conversant with the subject, and to deter many from joining us in the prosecution of the science; yet considerations of this nature must not be allowed to be carried too far. Every branch of human knowledge requires in proportion to its development an extension of its technical terms, without which its progress would effectually be checked. Had this been denied, the discoveries of Linnaeus or of Hedwig themselves had been nipped in the bud; and I must be allowed to state it as my opinion that many of the alterations ERIK ACHARIUS AND HIS INFLUENCE ON ENGLISH LICHENOLOGY 167 proposed by Dr Acharius in the nomenclature of the Lichens, however troublesome it may be to us at present to unlearn what we have long since learned, will be found not less important in extending the knowledge of these plants than his new system. Upon that propriety, or rather the necessity, of sub-dividing the numerous vegetables now arranged under the one vast genus, Lichen, and I believe all botanists, who have bestowed upon the subject an attention the most superficial, to be so fully agreed, that there is no occasion for a single argument to be employed: were any necessary, the most substantial one would be found in the number of British Species, which is already known to amount to 350, which is almost daily increasing, and which comprehends various tribes of a nature the most dissimilar to each other. It only remains for me, therefore, to express my obligations to my friend Mr Borrer, who has furnished me with the materials of the present paper, who has applied himself to the study of the indigenous Lichens with a zeal and success which I believe to be altogether unrivalled, and whose opinions, I am happy to add, coincide with my own.' (Turner, 1808). Acharius's gift of lichens to the Linnean Society of London 1805-1808 In a postscript dated 25 May 1804, J. E. Smith inquired of Acharius: 'If you could send the Linnean Society a tolerably complete collection of Lichens, good specimens named by yourself and referring to your works, they would be glad to make you any return by sending their Transactions of otherwise.' (Smith, 1804). This simple suggestion was to have far-reaching consequences and, though it was to take eight years for the mutual exchange to be successfully accomplished, guaranteed British lichenology a handsome share of original material upon which much succeeding lichen taxonomy would be based. Its value has only been widely recognized and appreciated following its purchase by the British Museum (Natural History) in 1963. To Smith's suggestion Acharius replied with warmth: 'Reflat sensu Tibi adnunciare, me ferulo elaboratae in paranda collectivae, qualitomum fiori potesste longletissima, Lichenum meorum, pro Societate Linneana. Sunt jam hunc in fincos circa 500 species designatae cum plurimus exorum varietatibus e modificationibus, sollicite papyro e nitida afixe atque adornatae, quibus priqutis, non visa mea adsoribenda fuit. Sed cum in dieu ad angetur tuo me collectis, etiam Genera quasi Species non raro mutentur e corrigantur, malui diferre missionem, quam earn professtinare; tamen decrevi proxima nave incuntis anni omnia ea mittere quae tune in parato sunt. Reliquae Species comparandae postea mitti posunt. Latin opeross fuit mea cura in haec collections conficienta nam instrumentem ? finimal e quousque fici potuit nitidam habere volui. Saepe specissima propria e unica bipartite coactus fui, ne quaedum Species ex illis desiderentur quarum exemplar dure potueram.' (Acharius, 1805). In reply to this Smith wrote to Acharius: 'Your letter of October 15, 1805 so full of information and candour should not have remained so long unanswered had I not but too good a reason for my silence, as well as for neglecting all business that was not absolutely necessary. This was my ill health. Ever since the beginning of November I have been more or less indisposed. My complaint was a carbuncle (anthrax) on the leg and for many weeks I could hardly sit up to write. It is now quite healed and I am going to London on the 13th for about two months as usual . . . The collection of Lichens which you are preparing for the Society will be a lasting monument to your fame and highly welcome to us. I hope this spring to forward to you all the volumes of our Transactions as a testimony of our gratitude. I shall propose this at the very first meeting of the Society at which I am present. As you have already made the collection so considerable I hope you will (as you say) send it by the first ship, for the Society has now a spacious and handsome house and we wish to increase our museum as much as possible . . . You have long been a Foreign Member of the Linnean Society and your name in the printed lists, of which I send you one for the year 1803. 1 know not why your diploma has not been sent but will enquire about it. The rule of not adding to the number of foreign members till it was reduced by death to 50 was dispensed with expressly in your favour, which has not been done for any other person . . . I cannot sufficiently express my admiration of your candour in what you say in answer to my remarks on botanical terms. All I am anxious about is to keep the science in as much classical purity as possible, and as your example will be of the very first weight (both as a Swede and as being at the head of your own department) I am very solicitous that you should co-operate with me in 168 DAVID J. GALLOWAY maintaining all such Linnean laws as experience has proved to be good - 1 will support no others. I would therefore be very sparing of new terms - as concise as possible in characters and definitions - and very cautious in changing names. There are very few writers at present who make their specific characters in the true spirit of our great master. This he justly calls "artis robur" and very few have equalled him in it. I thank you very much for your remarks on many new species of Lichens in your letter - 1 have not yet studied them all, but in most that I have examined I fully agree with you. I must take up the subject with attention soon in order to finish the 4th Vol. of Fl. Britca. , which is much wanted. I have not been able to procure you specimens of the shields of L. limbatus and fuliginosus , for I was prevented going to Wales (where they grow) last summer, nor do I know any method of procuring them. I will however, not forget your wishes. I have spent almost a whole day in looking over hundreds of specimens before I found any shields.' (Smith, 1806). Smith was as good as his word, and in a Council Minute of the Linnean Society of London for 21 May 1806 it was: 'Order'd, That a copy of the Transactions of this Society be presented to Dr. Acharius, F.M.L.S., upon his sending to the Society a Collection of specimens of lichens describ'd by him.' (Howe, 1912: 203). Meanwhile Dawson Turner, who was now thinking seriously of writing a general work on English lichens, wrote to Swartz: 'What an age it is since I had the pleasure of writing to, or hearing from you! I had flattered myself that, tho' I was silent, you would not have refused occasionally to have favoured me with a letter, and I am certain you would not have denied me this pleasure had you known how unfortunately I had been circumstanced since the cessation of our correspondence, now more than a year ago. Domestic calamities of various natures have kept my mind continually harrassed, and withdrawn my thoughts so effectually from Botany, that I hardly supposed I should ever be able to return to it. Among these misfortunes the most prominent have been the loss of a parent after a painful and distressing illness, and that of my only son torn from us in a moment by a calamity of which the remembrance is even now distracting. He was burned to death in his sleep, and that his mother, myself, and the rest of our babes did not share his wretched end was owing to a signal interposition of Divine Mercy. If from my friends Dr Smith or Professor Mertens, or from our English Papers you have heard of these miseries you will not have wondered that I have so long delayed writing to you: if you have not heard of them, I fear that both you and Dr Acharius will have thought me shamefully negligent, but I am satisfied that what I have written will but too well excuse me. To Dr Acharius I shall write by the next post ... I shall on the other side take the liberty of giving you a catalogue of my desiderata from the Methodus Lichenum. These plants particularly interest me, as, to divert my mind, I applied myself some time ago to the collecting materials for a Lichenographia Britannica, chiefly with a view to introducing among my countrymen the knowledge of Acharius' admirable dispositio; and, if Mr Borrer, Mr Harriman, and Mr Griffith will but co-operate with me as I wish, I shall not despair of producing a work that will be interesting to the students of this branch of botany.' (Turner, 1806a). In reply, Swartz wrote to Turner: 'I am charmed to hear that you have a design to elaborate a Lichenographia Britanicanica - it will no doubt be very considerable. The value you put upon my friend Acharius's Methodus is very flattering. He is now working upon a editio aucta atque emendata - or something of that kind, which will probably contain great improvements, as it has been in his power to see and observe an amazing deal more of his favourite tribe since the publication, which has indicated to him some - 1 believe very reasonable alterations of the arrangement, partly occasioned through observations from his friends, and from his own investigations upon the subject.' (Swartz, 18066). Later the same month (June) Swartz wrote again to Turner: 'Acharius may be able to do something and I suppose he intends to do it - during the course of a 12-month he has been preparing a collection for the Linnean Society's Museum, which will be the truest and surest guide to his Methodus. He intends to send off that collection this year. It will be a cadeau to the English amateurs of Lichenology.' (Swartz, 1806c). Turner, writing to Acharius in October, noted: ERIK ACHARIUS AND HIS INFLUENCE ON ENGLISH LICHENOLOGY 169 'I avail myself most readily of your obliging permission to write to you in my native tongue, for I really have so much forgotten Latin from disuse, and compose in it with so greatly difficulty that I never have recourse to it without reluctance, and without some apprehension lest I should not express my thoughts in the manner I intend. I received a few days ago the very kind and instructive letter, which you had the goodness to write to me on the 31st August, and I beg you to accept my thanks for the variety of information you have afforded me, and to be assured of the high sense I entertain of the friendly sentiments you express towards me. Pray believe that I shall always be most anxious to cultivate intercourse between us, and to shew myself deserving of the opinion you entertain of me; and pray favour me with your letters as frequently as possible. It gives me exceeding pleasure to hear that the Manuscript of your Lichenographia Universalis is in such a state of forwardness. All the botanical world will expect it anxiously, and be ready to receive from you, their "magnus Lichenum Apollo", the laws which you may be ready to lay down. For my own part I am so well satisfied with the Genera of your Methodus, and find them so useful that I am half sorry to hear of the changes you meditate. I hope you will not be offended at my presuming to beg of you not to establish Genera upon minute differences, unfit for common use; and at my begging still more strenuously that you would not alter specific names where it can possibly be avoided; even though you could substitute others more appropriate than those now in use. The confusion of Synonymy is the great hindrance to the present progress of botanical knowledge and it is particularly injurious in a tribe so difficult of themselves as the Lichens. Some of your new Genera I should wish to see inscribed with the names of those Botanists who have made themselves distinguished among these plants: I wish that no tribe has previously been dedicated to you, and that what you have called Parmelia might have been called Acharia: for myself I hope to have a genus when the Fuci are subdivided as they must be; but I should consider it a favour if you would call one of your Genera of Lichens Borrera, in honour of my friend Mr Borrer, whom I consider the most able Lichenologist in this Kingdom, and who is now working with me upon a Lichenographia Britannica. In this task we proceed very slowly on account of the many doubts and perplexities that we find at every step, nor shall we think of publishing anything till your Lichenographia Universalis had made its appearance that we may correct our errors by your knowledge, and follow your nomenclature. I will now take the liberty of offering a few remarks upon the observations you made on the Lichens I sent you, and if I am in error I trust you will correct me . . . [then follows a page of comments]. 'I have found many new things among the Lichens this summer, but have so nearly filled my paper that I must reserve all mention of them to my next letter when I will also communicate the characters of the new species lately figured in English Botany.' (Turner, 18066). In December Turner wrote to Swartz: 'I have been amusing myself lately with writing a monograph of the genus Opegrapha, and you would much oblige me by sending in your next letter morsels, however small, of Persoonii, nimbosa, vulvella, betuligna, rubella, prosodea, obscura, conglomerata, siderella, cerasi, scripta and dendritica; it appears to me that Dr Acharius has made too many species.' (Turner, 1806c). The emendations to the Methodus mentioned by Swartz and which had occupied Acharius for three years since the publication of that work were to be the basis of his next, and largest, work, the Lichenographia Universalis. In a letter to Smith dated 8 December 1807 (Fig. 10), Acharius gave details of its publication in Gottingen (to be supervised by Schrader), as well, as an intimation of the despatch of the lichens for the Linnean Society. Further details of the Lichenographia universalis are found in letters written in 1808 by Swartz to Smith and to Turner. Writing to Smith, Swartz observed: 'Even Acharius has proved the adversities of the times on account of his work the Lichenographia Universalis, which was to be printed at Gottingen, under the inspection of Prof Schrader (because the enterprise was too great for any home dealer in typography). The manuscript was, above 2/3 parts sent in locum last year, and some time after the printing began, we were shut up, that in the course of 19 months no account could be had. As for present appearances there are but little or no hopes yet to get out of the cage if not quite perished before. Dum delorant . . . Acharius wrote me some months ago, that he had then received intelligence about the box addressed to London for the Linnean Society that it was at last post varios caper arrived to England, but that he still wanted confirmation from you. It would be a real loss, if this sending should have miscarried, because a more instructive present the Society probably could not receive.' (Swartz, 18080). 170 DAVID J.

You may see how much I have been able to contribute to the completion of the Lichenologie. T'is in my opinion the most useful and complete of my works in that way.' (Acharius, 1813&). With the advice on the publication of the Synopsis (Fig. 15) made known to Smith and Turner, the lichenologists in England who would have had most use for it, Acharius ended his correspondence with botanists in England although he continued to hear of botanical progress in England through his friend Swartz. ERIK ACHARIUS AND HIS INFLUENCE ON ENGLISH LICHENOLOGY 175 Fig. 12 Hand-coloured plate (II) from Lichenographia universalis. Library, British Museum (Natural History). Swartz meanwhile, had also written to Nathaniel Winch of Newcastle in the same year, mentioning the new Synopsis: 'Mr Acharius's Lichenographia is a work of £4 value. If I can get it, I will contrive to send it, but this moment no copy is to be got here. A new Synopsis of Lichens (a compendium of the Lichenographia) is just printing and this I shall certainly be able to dispatch another season.' (Swartz, 1813a). Turner, who had espoused Acharius's views most strongly, still received letters from Swartz from time to time, and in them lichens were always discussed. Swartz was keenly interested in the progress of Turner's Lichenographia. In 1816 Swartz observed to Turner: '. . . my friend Dr Acharius has pursued his old task, the Lichenologia, and his last opusculum is the Synopsis, which contains indeed multum in parvo. The very great addition he got not only from 176 DAVID J. GALLOWAY A.. 4tV>.'*-»*1.41' / f— . * ' ~ ' '^MBiJiiEg^ LECIDEA. GENUS VI. j - ..... - LECIDEA. Aca i /> ACR. RES. OBDIKH OE WAIA, MED. DOCT.

(Swartz, 1818). One month before his death in September 1818, Swartz wrote to W. J. Hooker: 'How goes it with the Lichenographia of Messrs Turner and Borrer, (quoted frequently in Engl. Bot. as in manuscript?) I suppose nothing is published yet, as I have not seen it announced anywhere. The tracts of M. Acharius which I send you upon the Calicioidea* may perhaps be of some service for extricating doubtful points on this tribe of the Lichen family.' (Hooker, 1840). Although the Linnean Society later published Acharius's account of the new lichen genera Glyphis and Chiodecton (Acharius, 1818), it was in his earlier works and in his encouragement and example to Smith and Turner where his impact on lichen taxonomy was most strongly felt. This influence later affected the rising generation of English lichenologists (Hooker, 1821, 1833; Gray, 1821; Greville, 1824, 1826; Taylor, 1836; Leighton, 1851, 1854, 1856; Lindsay, 1856; Mudd, 1861). Through the fine collection now in the herbarium of the British Museum (Natural History) the concepts of Acharius still have considerable relevance to contemporary studies in lichen taxonomy (e.g. Tibell, 1978, 1987). * Acharius (1815, 1816, 1817); see also Tibell (1987). ERIK ACHARIUS AND HIS INFLUENCE ON ENGLISH LICHENOLOGY 179 The Acharius lichens in the British Museum (Natural History) (BM-ACH) The collection of lichens sent to London by Acharius as a gift to the Linnean Society of London was neglected for many years, the specimens attached to their cards being kept loose in drawers in a cabinet. In April 1961 the collection was removed to the herbarium of the British Museum (Natural History) by Mr P. W. James, Mr J. R. Laundon (BM), and Dr R. Santesson (University of Uppsala). In 1962-63 Mr J. R. Laundon curated the collection into its present state, a painstaking task of which he later noted 'the specimens were on their present cards, which were kept loose in drawers and which were so black with dirt that one had great difficulty in reading the names on many of the specimens. It took me several months work just to remove this dirt from the labels and material . . .' (J. R. Laundon, pers. comm.)

The lichen collection in BM-ACH illustrates Acharius's taxonomic arrangement used in the Lichenographia Universalis, with names from the earlier Methodus in parenthesis or scored out (Hawskworth, 1977: Fig. 3). Acharius's catalogue (Fig. 16) of the collection entitled 'Lichenes: ad Angliam pro Museo Societatis Linnaeanae Londinensis A° 1807 ab E. Achario missi' comprises 894 specimens in 41 genera arranged as follows: Spiloma 1-12; Arthonia 13-27; Solorina 28-29; Gyalecta 30-33; Lecidea 34-177; Gyrophora 178-194; Calicium 195-220; Opegrapha 221-261; Graphis 262-275; Biatora 276; Verrucaria 277-322; Endocarpon 323-335; Trypethelium 336; Porina 337-340; Thelotrema 341-343; Pyrenula 344-347; Variolaria 348 -359; Sagedia 360-363; Urceolaria 364-384; Lecanora 385-551; Roccella 552-553; Evernia Fig. 18 Specimen of William Borrer's observations on the Acharius lichens.

The lichens are attached to water-marked paper glued on to card, 11-12 x 7-8 cm and are named in ink by Acharius (Fig. 17). They are housed in packets mounted on herbarium sheets and enclosed in folders in the order stated in Acharius's catalogue. Tibell (1987: 258) has recently commented on the BM-ACH collection as follows '. . . specimens seem first to have been annotated according to Methodus Lichenum, and when the annotations were revised "mscr." (manuscript) and "Lichenogr. universal." were added. The "mscr." has been crossed out, possibly by Acharius himself after finishing the Methodus and Lichenographia universalis manuscripts. The drawback of the BM-ACH material is that no information on collectors or localities is supplied with the specimens. Its importance arises from the fact that this was probably part of the material Acharius was working with when he wrote the "Methodus" and "Lichenographia".' This view was stated by Swartz in letters to Turner (see p. 168 above) when he wrote that Acharius had spent a year preparing a named set of lichens '. . . which will be the truest and surest guide to his Methodus' (Swartz, 1806c). William Borrer (1781-1862) saw the Acharius lichens snortly after their arrival at the Linnean Society, examined them carefully and prepared manuscript comments on them dated 25 May 1809 and 22 November 1811 (Fig. 18). These comments are maintained with the Acharius catalogue in BM-ACH. J. R. Laundon (BM) has prepared a detailed list of the BM-ACH collection including several additional taxa not included in the Acharius holograph catalogue. The full BM-ACH holding is shown in Table 1 .

British Museum (Natural History) MACROLICHENS OF EAST AFRICA T. D. V. Swinscow & H. Krog Dr Swinscow was formerly Deputy Editor of the British Medical Journal. Dr Krog is Professor of Taxonomic Botany at the University of Oslo. This book is based mainly on collections made in the field by the authors. It covers 77 genera and 629 species. It is the first substantial study of a tropical lichen flora to be undertaken by modern research methods. Thin-layer chromatography has been used throughout, and the great majority of species have been studied by microscopic examination of microtome sections. The nomenclature has been thoroughly revised, and in all cases the basionym is given. The book will be indispensable to students of the lichens of the African continent and valuable to readers interested in lichens throughout the tropics.
