612 MUSCI. (MOSSES.) 



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

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

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

 apex, nor are the cortical utricles of the branches marked with striae, as they 

 are in the last-named species.) 



8. S. sedoides, 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 vinous red, oval, entire at the apex, not mar- 

 gined ; when dry absorbing moisture with difficulty ; flowers and fruit not seen 

 Springy places, on Table Rock, S. Carolina, Gray, Lesquereux: Mt. Marcy, 

 New York, Torrey. (In the first-mentioned locality occurs an olive-green 

 variety, (?) perhaps S. Pykesii, 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. sqtiarrosum, Pers. Monoecious; stems 8' -12' long, robust, 

 rigid ; branches dcflexed, attenuated, 5 in a fascicle ; branch-leaves ovitto-acumi- 

 nate, squarrose; stem and perichoetial leaves oblong, obtuse, not fibrillose. 

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

 large species. (Eu.) 



10. S. macropliyllum, Bernliardi. 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 remarkable for the absence of a spiral 

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

 sea-coast, New Jersey to Florida : also Raccoon Mts., Alabama, Lesquereux. 



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



of the leaf. 



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

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

 late, obtuse, not fibrillose ; branch-leaves ovate-lanceolate, tapering to a narrow 

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

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

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

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



12. S. (iiBi3>B ifituii). Wils. Monoecious; much like and formerly 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, Drummond. (Eu.) 



13. S. tablllare, 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 undulate 

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

 sporules golden-yellow. (S. acutifolium, var. 1 Muse Alleqhan.) Table
