Moist peaty places in mountain districts. 



Aland Islands, Shore of Loch Katrine, New Orleans, Alabama, 

 New Jersey. 



Dr. Braithwaite then intimates his intention to add descriptions 

 of three natives of North America which have not yet been found 

 in Europe, and commences with — 



Sphagnum Pylaiei. Bridel. CSidlivant Icon. Muse, %>. 12, t. 6.J 

 Dioicous ? olive green, fuscous, or blackish ; stem erect, undivided, 

 slender, 2-4in. high with a single layer of small cortical cells, and 

 a narrow reddish brown woody layer ; branches all solitary or in 

 pairs at the lower part of the stem, short, terete, obtuse, arcuato- 

 decurved, the cortical cells small, retort cells few, narrowly cylindric, 

 not recurved at apex. 



Stem leaves numerous, laxly imbricated, erect, ovate-oblong, 

 concave, rounded and minutely erose at apex, the hyaline cells 

 fibrillose. Branch leaves laxly imbricated, very small, ovate, 

 obtuse, the margin incurved in the upper third, entire at apex ; 

 hyaline cells with strong annular fibres, and without pores, in sec- 

 tion circular, separated both in front and back by the chlorophyll 

 cells, which are very thick and obtusely trigonous. 

 Peat bogs.

 York, New Jersey.

 p. 750. 



Stem procumbent at base 3-5in. high, simple or with a few short, 

 scattered branches, fragile, flaccid, dull pale green, the upper part 

 vinous red. Leaves large, very densely imbricated, oblong-ovate, 

 concave, obtuse, entire, or eroso-denticulate, with a border of two 

 rows of extremely narrow cells ; hyaline cells elongated, with 

 annular fibres, and very few minute pores. Branch leaves similar 

 but smaller. 

 Peat bogs.

Sphagmnn Pilaiei and its variety have been regarded by most 

 authors as doubtful species, partly because they have never been 

 found in fruit ; the structure of the leaves and stem is, however, so 

 distinct that there can be no hesitation in maintaining the right of 

 S. Pilaiei, as the most highly developed form to the title of specific 

 rank. — Monthly Micro. Journ., June, 1875. 



Sphagnum Portoxicense. Hampe (Linn, 1852, p. 359.J 

 Dioicous ? in large soft tufts, pale fuscous below, pale glaucous 

 green above. Stems 8-14 in. high, stout, simple or bipartite, 

 firm, pale brown ; cortical cells in 2-3 layers, containing spiral 

 fibres, but few pores. Stem leaves auricled, erect or deflexed, 

 subquadrate-ovate, fringed round the entire margin, upper cells 

 rhoinboidal, lower elongated, all without fibres or poi'es.
