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 strice, as they 

 are in the last-named species.) 



8. S. sedoMes, 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. Pylajsii, 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 oral, situated centrally between the rotund utricles, and extending to both 



surfaces of the leaf. 



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

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

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

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

 large species. (Eu.) 



10. S. Eiiacrophylfitlin, Bernhardi. 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 perichanial 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. -r 



11. S. at' uti folium, 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. rnbellum, 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. fimbl'iatUlBI, Wils. Monoecious; much like and formerly coil' 

 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. lEu.) 



13. S. tabulate, Sulliv. Stems 2' - 3' high, closely csespitose ; 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 ; perichtetial leaves lanceolate, acute, broadly bordered above ; 

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