42 A MANUAL OF MOSSES 



border of 2-A thick-walled, linear-prosenchymatous cells; 

 chloroph} Hose cells in cross-section barrel-shaped with both 

 ends ex;50sed : fruit unknown. 



In wooded swamps and wet shaded places, Europe and 

 North America. Not yet widely collected. 



Fayette : In pools and wet cavities in shaded rocky 



bed of river near falls, Ohio Pyle, June 

 14, 1908. O. E. J. (Figured). 

 Westmoreland : On springy shaded hillside, Laurel Hill 

 Mts., Mellon's estate, New Florence, Sep- 

 tember 9-11, 1907. O. E.J. 



18. Sphagnum subsecundum Nees. 

 (Plate V) 



Moderately densely cespitose, green to yellowish or 

 brownish : stems 5-20 cm. long, with a dark or purplish-brown 

 wood-cylinder, with a cuticular sheath of one layer of moder- 

 ately inflated cells ; stem-leaves small, about 0.6-0.8 mm. long, 

 broadly short-lingulate, somewhat auriculate, the margin 

 broadly hyaline-bordered below, the border narrowing and be- 

 coming fimbriate towards the broadly erose-fimbriate apex, 

 the upper half of the stem-leaves often distinctly concave and 

 more or less cucuUate; hyaline cells of the stem-leaves broad 

 above, usually all non-fibrillose, rarely a few septate, some- 

 times porose ; of the 3-5 fasciculate branches two or three 

 are variously divergent, short, usually 6-8 mm. long, slender 

 and sometimes flagelliform; branch-leaves small, 1-1.5 mm. 

 long, very concave, broadly ovate to lanceolate, acuminate to 

 a narrowly truncate and 3-5-toothed apex, the margins uni- 

 formly narrowly hyaline-bordered, involute, when dry closely 

 imbricate to more or less sub-secund ; hyaline cells of branch- 

 leaves narrow, richly fibrillose, ventrally non-porose, or with 

 a few small non-ringed pores in the cell-angles, dorsally with 

 numerous small ringed pores along the sides of the cells; in 

 cross-section the chlorophyllose cells narrowly barrel-shaped, 

 relatively rather large as compared with the hyaline cells, free 

 on both faces, the hyaline cells but slightly convex on either 

 side : spores not seen from our region, finely papillose, yellow- 

 ish, and .025-028 mm. in diameter. 



In wet meadows, swamps, ditches, bogs, etc., in Europe 

 and in Asia and, in North America, from Newfoundland to 

 Alabama. In our region rare and approaching the variety 

 brachycladum Warnstorf in having stem-leaves more or less 

 cucullate and the divergent branches often only about 5 mm. 

 long. 



Erie : In bog at south end of Cranberry Pond, 



Presque Isle, May 8-9, 1906. O. E. J.
