uniform and similar, 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 lanceolate
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; perichætial
bracts 6-9, lax oblong-ovate, uppermost convolute, truncate
and toothed at apex, the areolation resembling that o f the branch
leaves. Capsule small, on a shortish slender peduncle. Spores
sulphur-coloured.
Male plant and prothallium unknown.
H a b.— Sandy bogs. Rare.
N. A m e r ic a .— 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 o f fibrils.
In general aspect it resembles the plumose state o f Sph. cuspidatum,
or even some forms o f Hypnum fluitans, to which also the
areolation at first sight somewhat approximates.

Sph. tenellum var. longifolium.
Snowdon, near Llanberis (Boswell, 1874).
Sph. magnifolium, W il s . M ss. in Herbar. suo,* probably also Sph. Kinlayanuin,
W il s . in schedis.
Ben Wyvis, Ross (McKinlay).
I can see in this only a form of Sph. subseamdum var. contortum, having very
large stem leaves, evidently developed at the expense of the branches, which are few
and distant or nearly absent; the comal branches are, however, quite normal.
