88 THE SPHAGNACE^ OR PEAT-MOSSES OF EUROPE, ETC. 



uniform and simil.i.r, divergent, dependent, straight, subflabellate, 

 lax-leaved, the cuticular cells short, uniform, with few pores. 



Branch leaves rather rigid, subdistichous, small at base of 

 branch, soon becoming elongated, narrowly lanceolate and lanceo- 

 late-subulate, involute-concave, bordered by 1-2 rows of extremely 

 narrow cells ; apex somewhat truncate, with 7-8 teeth. Hyaline 

 cells elongated, flexuoso-fusiform, with 6-10 pores in a longitudinal 

 median line, free from fibres ; chlorophyllose cells circular in 

 section, separating the hyaline both in front and back. 



Fruit in the upper fascicles or in the coma, divergent ; peri- 

 chcetial bracts 6-9, lax oblong-ovate, uppermost convolute, truncate 

 and toothed at apex, the areolation resembling that of the branch 

 leaves. Capsule small, on a shortish slender peduncle. Spores 

 sulphur-coloured. 



Male plant and prothallium unknown. 



Hab. — Sandy bogs. Rare. 



N. America. — Near Philadelphia (Bernhardi) ; Swamps in Louisiana (Drum- 

 mond) ; Raccoon Mountains, Alabama (Lesquereux) ; Green County (Mississippi 

 (Tice) ; New Jersey (Austin) ; Wilmington, N. Carolina (Sullivant). 



Quite peculiar among the Sphagna, by the uniform branches, 

 the slender pendent ones, ordinarily present, being wanting, and 

 also by the central position of the pores, and total absence of fibrils. 



In general aspect it resembles ths plumose state of Sph. aispi- 

 datnm, or even some forms of Hypnum fiiiUans, to which also the 

 areolation at first sight somewhat approximates. 



• ADDENDA. 



Sph. tenellum var. lougifolium. 



Snowdon, near Llanberis (Bos well, 1874). 



Sph. magtiifoUufn, Wils. Mss. in Her])ar. suo, probably also Sph. Kinlayanum, 

 WiLS. in schedis. 



Ben Wyvis, Ross (McKinlay). 



I can see in this only a form of Sph. subsccuiidiim var. contortum, having very 

 large stem leaves, evident!}- developed at the expense of the branches, which are few 

 and distant or nearly absent ; the comal branches are, however, quite normal.
