612 (12) Musci. (mosses.) 



and No. 8 maybe sterile forms or incomplete states of two species yet unknown. 

 They approach nearer to S. cymbifolium than to any other species; but their 

 leaves hare a closer reticulation, and are not papillose on the back near the 

 apex, nor are the coitical utricles of the branches marked ■nith stii^, as they 

 are in the last-named species.) 



8. S. sedoldeS; Brid. Form and ramification of the stem and cross- 

 section of the leaf same as in the last, but a somewhat smaller plant, and not so 

 flaccid ; leaves mostly of a dark \inous red, oral, entire at the apex, not mar- 

 gined ; when diy absoi'bing moistui-e with difficulty ; flowers and fniit not seen. 

 — Spiingy places, on Table Eock, S. Carolina, Gray, Lesquereux: Mt. Marcy, 

 New York, Torrey. — (In the fii'st-mentioned locaUty occm-s an oUve-green 

 variety, (?) — perhaps S. Pylffisii, Brid. — smaller in all its parts; branches 

 somewhat numerous, short, mostly single, and with closely-imbricated leaves, 

 much smaller than the distantly placed stem-leaves. — (Muse. Bor.-Amer., No. 4. ) 



* * Ducts oval, situated centrally between the rotund utricles, and extending to both 



surfaces of the leaf. 



9. S. sqwarrdsnm, Pers. Monoecious ; stems 8' - 12' long, robust, 

 rigid ; branches deflexed, attenuated, 5 in a fascicle ; branch-leaves ovate-acumi- 

 nate, squarrose; stem and perich^tial leaves oblong, obtuse, not flbrillose. — 

 Bogs, &c. ; common in the Northern and Jliddle States, and westward. — A 

 large species. (Eu.) 



10. S. niacropliyllum, Bemhardi. Stems slender, stiff, reddish, 4'- 

 6' long ; branches short, flat, flabelliform, 2-3 in a fascicle; branch-leaves long, 

 subulate, straight, spreading, dentate at the apex ; utricles elongated, with 7-9 

 large pores in a line along the centre, and remai'kable for the absence of a spkal 

 fibre ; capsule oblong, concealed by the perichsetial leaves. — Swamps near the 

 sea-coast. New Jersey to Florida : also Eaccoon Mts., Alabama, Lesquei-eux. 



* * * Ducts triangular, situated between the rotund utricles next the concave surface 



of the leaf. 



11. S. acntifolium, Ehrh. Monoecious; stems 5' -10' long, slender; 

 branches crowded, elongated, attenuated, mostly pendent ; stem-leaves Ungu- 

 late, obtuse, not flbrillose ; branch-leaves ovate-lanceolate, tapering to a naiTow 

 truncate point, erect-patent; capsule much exserted. — Erequent; variable in 

 size : foliage often tinged with red. — S. nibeUum, Wils. (common in Europe), 

 closely resembling this, but a smaller species, %vith elliptical leaves and dioecious 

 inflorescence, may be looked for within our limits. (Eu.) 



12. S. fimbriatum, Wils. Monoecious; much like and fonncrly con- 

 founded with No. 11, but a more delicate species, with fimbriated stem-leaves, 

 and large, conspicuous, obovate, obtuse, and cucullate perichsetial leaves. — 

 British America, Drammon J. (Eu.) 



13. S. tabulare, Sulliv. Stems 2' -3' high, closely casspitose; branches 

 densely crowded, short, erect-patent ; stem-leaves large, oblong, obtuse or acute, 

 fibrillose ; branch-leaves ovate-acuminate, the upper half spreading and imdulate 

 on the margins ; perichoatial leaves lanceolate, acute, broadly bordered above ; 

 sporules golden-yellow. — (S. acutifolium, var. ? Muse. Alleghan.) — Table
