Part 12

BRYUM. (WEBERA) SCHIMPERI. Wils. (_non_ Bry. Eur.) L. more rigid, erect, narrow, lanceolate, less decurrent, nerve stronger, continued almost to apex; areolæ a little longer and more obscure. [Hunt, l. c.]

_Debris_ of micaceous rock. VII.

Ben Lawers, Perthshire Mts., Snowdon.

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.]

III. ERRATA.

p. 57. Head line, “c” inverted.

„ 71. line 9, for “obtuse,” read “acute.”

„ 81. line 5 from bottom, specific name should begin with a capital M.

„ 99. for “TETRADONTIUM” read “TETRODONTIUM.”

„ „ last line, before “long” read “l.”

„ 127. line 17, for “hexaganal” read “hexagonal.”

„ 141. line 6 from bottom, for “Nowcll” read “Nowell.”

„ 152. line 5 from bottom, for “EURYNCHUM” read “EURYNCHIUM.”

„ 139. line 3, for “ANÆCTANGIUM” read “ANŒCTANGIUM.”

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_:—
