Title: A Synopsis of the British Mosses

Containing Descriptions of All the Genera and Species, (With Localities of the Rarer Ones) Found in Great Britain and Ireland, Based Upon Wilson’s “Bryologia Britannica,” Schimper’s “Synopsis,” Etc.

It is not my desire that this little volume should be looked upon as anything more than what is expressed in the title, simply “A Synopsis of the British Mosses,” and as a kind of vade-mecum to the working Bryologist, as well as a guide to beginners. It is not altogether an original work, nor yet is it a mere compilation, for nearly every species has been carefully examined under the microscope before being described, and then the diagnoses compared with other works, principally that great text-book of British Bryologists, “Wilson’s Bryologia Britannica.” Besides this work, I have also largely consulted, and drawn from, Bruch and Schimper’s “Bryologia Europæa,” Schimper’s “Synopsis,” Dr. Mueller’s “Synopsis,” the Proceedings of the Linnean Society, the Bulletins of the Royal Botanical Societies of France and of Belgium; and last, but not least, the valuable papers recently contributed by Dr. Braithwaite to “Journal of Botany,” “Grevillea,” and the “Monthly Microscopical Journal,” and also some papers by Mr. Mitten in the first-named publication.

In the general arrangement of the genera and species, I have mainly followed the “Bryologia Britannica,” as I did not consider myself justified in departing widely from it, although many of our principal Muscologists look upon it as very faulty; but I did not hold my authority sufficient to alter what has become a classical arrangement amongst us: and more particularly as both Dr. Braithwaite and the Rev. J. Fergusson are engaged upon more critical examinations, prior to the publication of new and more natural arrangements. The Analysis of the Genera is principally founded upon the same part from Wilson, and is intended not as an arrangement, but merely a key.

viIn the “Appendix” will be found a few omitted species, and alterations of nomenclature, as well as a few errata, which should be noted in the margin at their proper places.

I much regret that, by an oversight, I have omitted to insert var. δ squarrosulum under Sphagnum cymbifolium, gathered by my friend Mr. Bagnall, in Sutton Park, Birmingham; and the same locality should be added after Hypnum aduncum, H. Sendtneri, and H. intermedium.

I must here express my gratitude and thanks to those gentlemen who have so kindly assisted me in its preparation, both with the loan or gift of specimens of the rarer and newer species, and also for the diagnoses received from several, where specimens were not attainable. Amongst these gentlemen I must specially thank Dr. Hooker for his kind permission to use the Herbarium specimens and Library at Kew, and Mr. J. G. Baker, F.L.S., for his valuable assistance in doing so; also Dr. Braithwaite, F.L.S., Mr. J. Bagnall, of Birmingham; Dr. F. Buchanan White, of Dunkeld; Dr. Fraser, of Wolverhampton; Rev. J. Fergusson, of New Pitsligo; Mr. Carruthers, F.L.S., of British Museum; Mr. G. E. Hunt, of Manchester; Mr. John Sim, of Strachan; Mr. W. Galt, of Edinburgh; M. P. Goulard, of Caen, Calvados; and lastly, all those gentlemen and ladies who so readily came forward as subscribers to the number of upwards of 200, to assist in the publication of the volume.

It is my intention, as soon as sufficient material can be accumulated, to publish “A Geographical Distribution of the British Mosses,” and, in furtherance of this object, I should esteem it a great favor if all collectors throughout the kingdom would kindly be at the trouble of forwarding to me, as early as convenient, complete lists of the Mosses found by themselves or their friends, in their several districts, with any notes they may think desirable respecting them, and, where possible, the range and habitat of the various species. I feel sure I have only to mention this to ensure an abundant return of information for a work which is really wanted, and shall, so far as any exertions on my part can ensure it, be really valuable.

II. ALTERATIONS OF NOMENCLATURE, AND SYNONYMS.

No. 54. W. truncicola De Not. =

Dicranum montanum. Hedw. “Having shown the specimen to Prof. Lindberg during his recent visit, he 188informed me that he was under the impression that Juratzka had referred it to Dic. montanum; and on comparing the two I find they are truly identical. The species is, however, none the less an addition to our flora.... its place will be next to D. strictum.” [Dr. Braithwaite, in Grevillea i., p. 75.]

No. 71. Dicranum polycarpum. β. strumiferum = Oncophorus strumifer. Brid.

ONCOPHORUS. Brid.

L. spreading flexuose from a sub-decurrent base; caps. cernuous incurved, neck shortly and widely strumose, not striate.

O. strumifer. Brid. “This is again restored to the rank of a species, as it differs from O. polycarpus (Dicranum) in the caps. being more or less cernuous, constantly strumose at base, with a compound annulus, and in the leaves having papillæ only on the upper surface.” [Dr. Braithwaite, Jour. Bot. VIII. 228.]

84. Dicranum heteromallum. δ. sericeum.

Add as a synonym, Dicranodontium sericeum. Schp.

85. D. Starkii. β. molle =

D. arcticum. Schp. Its general appearance better distinguishes it from D. Starkii than its microscopical characters. It is quite erect, growing in large loose patches, stems 3–4in., elastic, very robust; foliage of a fine purplish brown colour; leaf wider below, and more suddenly contracted upwards, with a thinner nerve; fruits earlier. [Hunt. l. c. p. 321.]

Ben-mac-dhui and Ben Nevis.

92. D. circinnatum. Wils.

Add as synonyms Dicranodontium aristatum. Schp. D. asperulum. Mitt.

18996. D. palustre. Brid. Dr. Braithwaite points out in Grevillea I., 109, that La Pylaie’s specimens of this moss (Bridel Bryol. Univ. I. 814) belong to Campylopus flexuosus, as shewn by De Notaris in his Epil. Bryol. Ital.; and that hence the name D. Bonjeanii, De Not. is to be preferred. The synonymy would then stand:—

96. D. Bonjeanii. De Not. Syllab. Muse. 213 (1838); Muell. Synopsis I., 369 (1849). D. palustre. Bry. Eur. and Bry. Brit., p. 79 (non Bridel.) D. undulatum. Turn. Musc. Hib.

The following amended diagnosis of this species is from the same author (in Grev. i., 109):—“Seta solitary; st. erect; l. more or less erecto-patent, straight, from a broad linear flat base, broadly oblong-lanceolate, gradually narrowed into a strap-shaped point, tapering into an acute apex, lightly undulate above, canaliculate; margin acutely serrate above, teeth uniform in shape and direction; nerve very narrow, vanishing below apex, smooth at back; basal cells short quadrate, brownish, above elongate hexagonal or parallelogramic, uppermost elliptic-oblong.”

361. E. minimum, Hunt. is now ascertained to be Splachnobryum Wrightii, Muell., and can hardly be considered as indigenous, “for the spores have most probably been mixed with soil attached to some exotic, and thus accidentally scattered on the wall where it was found.”—[Braithwaite.]

SPLACHNOBRYUM. C. Muell. Verhand. Zool. Bot. Ges. Wien, 1869. p. 501.

“Calyp. dimidiate, enclosing the whole theca and embracing spirally the upper part of the seta, cleft at side, smooth, 190fugacious. Perist. simple, arising below mouth of caps., teeth 16 very narrow, linear-lanceolate acicular, with the articulations remote. Columella immersed. Dioicous, male fl. gemmaceous, without paraphyses. Plants small slender, with distant spathulate leaves.”

S. Wrightii. Muell. l. c. (Entosthodon minimus, Hunt. l. c. Amblyphyllum Hibernicum, Lindb. MS.)

“St. ¼–⅓in. simple sub-flexuose, pale red, slightly radiculose; l. bright green distant (base narrow, slightly decurrent), patent, flattish, obovate or spathulate, rounded at apex, margin reflexed below, entire or minutely serrulate in male, crenulate above in female plant, nerve thick, prominent at back, vanishing below apex; cells large lax, pellucid, smooth, incrassate, rhombo-rectangular at base, rhomboidal above, smaller and nearly circular at margin; caps. erect, obconical at base, sub-cylindrical, wide-mouthed, pale brown; seta slender, twisted to left; lid conical acute.” [Dr. Braithwaite, l. c.]

Selection of 24, 3s., post free. Also other interesting unmounted objects, suited to the requirements of Amateur Microscopists, prepared by

Subscriptions for 1873 (12s. post free in the United Kingdom) payable in advance to the publishers, Messrs. Ranken and Co., Drury House, St. Mary-le-Strand, London, W.C., of whom may be obtained the volume for 1872 (price 16s. 6d. bound in cloth); also covers for the volume (price 1s.), and back numbers.

⁂ A good introductory series of books on Natural History for the use of students and amateurs is still a desideratum. Those at present in use have been too much compiled from antiquated sources; whilst the figures, copied in many instances from sources equally antiquated, are far from accurate, the colouring of them having become degenerated through the adoption, for the sake of cheapness, of mechanical processes.

The present series will be entirely the result of original research carried to its most advanced point; and the figures, which will be chiefly engraved on steel, by the artist most highly renowned in each department for his technical knowledge of the subjects, will in all cases be drawn from actual specimens, and coloured separately by hand.

Each work will treat of a department of Natural History sufficiently limited in extent to admit of a satisfactory degree of completeness.
