PREFACE.

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.

In 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.

NOTICE TO COLLECTORS.

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.

The diagnoses of this and the next four species are from his pen; the name aduncum should be retained as being older than exannulatum.

St. 1½in. reddish brown and procumbent below, light green above, l. ovate, decurrent, erecto-patent, concave, serrate towards apex, margin recurved, thinly nerved nearly to apex, areolæ narrow elongate, upper acute at both ends, lower quadrate; male fl. terminal discoid, outer perig. l. spreading elliptic-lanceolate, saccate at base, margin strongly recurved, apex cucullate serrate; inner obovate, suddenly acuminate; perich. l. linear-lanceolate, strongly nerved; caps. oval pendulous, glaucous green when young, pale reddish brown when ripe, on a slender seta geniculate at base.

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 informed 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.

96. 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, fugacious. 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.]

LIST OF WORKS

PUBLISHED BY

L. REEVE & CO.

NEW SERIES OF NATURAL HISTORY FOR BEGINNERS.

⁂ 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.

The following are now ready:—

1.F.

1.F.1. Project Gutenberg volunteers and employees expend considerable effort to identify, do copyright research on, transcribe and proofread works not protected by U.S. copyright law in creating the Project Gutenberg™ collection. Despite these efforts, Project Gutenberg™ electronic works, and the medium on which they may be stored, may contain “Defects,” such as, but not limited to, incomplete, inaccurate or corrupt data, transcription errors, a copyright or other intellectual property infringement, a defective or damaged disk or other medium, a computer virus, or computer codes that damage or cannot be read by your equipment.

1.F.5. Some states do not allow disclaimers of certain implied warranties or the exclusion or limitation of certain types of damages. If any disclaimer or limitation set forth in this agreement violates the law of the state applicable to this agreement, the agreement shall be interpreted to make the maximum disclaimer or limitation permitted by the applicable state law. The invalidity or unenforceability of any provision of this agreement shall not void the remaining provisions.

1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the trademark owner, any agent or employee of the Foundation, anyone providing copies of Project Gutenberg™ electronic works in accordance with this agreement, and any volunteers associated with the production, promotion and distribution of Project Gutenberg™ electronic works, harmless from all liability, costs and expenses, including legal fees, that arise directly or indirectly from any of the following which you do or cause to occur: (a) distribution of this or any Project Gutenberg™ work, (b) alteration, modification, or additions or deletions to any Project Gutenberg™ work, and (c) any Defect you cause.

Many small donations ($1 to $5,000) are particularly important to maintaining tax exempt status with the IRS.

The Foundation is committed to complying with the laws regulating charities and charitable donations in all 50 states of the United States. Compliance requirements are not uniform and it takes a considerable effort, much paperwork and many fees to meet and keep up with these requirements. We do not solicit donations in locations where we have not received written confirmation of compliance. To SEND DONATIONS or determine the status of compliance for any particular state visit www.gutenberg.org/donate.

While we cannot and do not solicit contributions from states where we have not met the solicitation requirements, we know of no prohibition against accepting unsolicited donations from donors in such states who approach us with offers to donate.

International donations are gratefully accepted, but we cannot make any statements concerning tax treatment of donations received from outside the United States. U.S. laws alone swamp our small staff.

Please check the Project Gutenberg web pages for current donation methods and addresses. Donations are accepted in a number of other ways including checks, online payments and credit card donations. To donate, please visit: www.gutenberg.org/donate.

Section 5. General Information About Project Gutenberg™ electronic works

Professor Michael S. Hart was the originator of the Project Gutenberg™ concept of a library of electronic works that could be freely shared with anyone. For forty years, he produced and distributed Project Gutenberg™ eBooks with only a loose network of volunteer support.

Project Gutenberg™ eBooks are often created from several printed editions, all of which are confirmed as not protected by copyright in the U.S. unless a copyright notice is included. Thus, we do not necessarily keep eBooks in compliance with any particular paper edition.

Most people start at our website which has the main PG search facility: www.gutenberg.org.

This website includes information about Project Gutenberg™, including how to make donations to the Project Gutenberg Literary Archive Foundation, how to help produce our new eBooks, and how to subscribe to our email newsletter to hear about new eBooks.
