I. ADDITIONAL SPECIES.
Sphagnum laricinum. Spruce. (S. neglectum, Angst.) St. 4–6in. solid, the bark pale, of 2–3 layers of cells. Br. fascicles more or less crowded, of 3–4 br., of which one or two are divergent, the others pendent, but not appressed nor acute. St. l. small ovate, cucullate at apex, at last minutely fimbriate, patent or reflexed; basal cells hyaline utricular, the middle and lateral very narrow, the apical rhomboid, with scarcely any fibres or pores; br. l. sub-secund, recurved at point, ovate, shortly and bluntly acuminate, the point with 3–5 teeth, margin recurved above, rather broadly bordered; hyaline cells serpentine elongate, with many threads and pores; caps. scarcely exserted. [Dr. Braithwaite, Monthly Micros. Jour., 1872, p. 159.]
Deep bogs.
Terrington Carr, Yorkshire, 1846 (Spruce); Holyhead (Wilson); Braemar, 1868 (Hunt).
Dicranum undulatum. Ehr. St. naked and decumbent at base; l. patulous, upper falcato-secund or appressed and slightly secund from a broad oblong base, lanceolate, gradually narrowed into a dagger-shaped point ending somewhat abruptly in the acute apex, beautifully undulate in the upper half, carinate; margin revolute below, coarsely serrate above with spinulose irregular teeth; nerve flattened, narrow and extended to apex, narrowly two-winged and serrate at back; cells elongate oblong or elongate hexagonal, those of central base sub-quadrate and hyaline. [Dr. Braithwaite, in Grevillea, i., 108.]
Stockton Forest, near York, 1842 (Spruce); again 1872 (Mr. Anderson). It has doubtless been frequently overlooked or mistaken for D. scoparium or D. Bonjeanii (palustre).
Bryum (Webera) Breidleri. Juratzka. Dioicous. 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. [Hunt. Mem. Lit. and Phil. Soc., Manchr., 1871–2, p. 101.]
Wet debris of slaty rocks near springs. VII. VIII.
Glen Callater, Loch-na-gar, Carnlochan Glen (Hunt).
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.
