above the middle and scabrous at the cucullate apex, with the
triangular ducts free on the concave side of the leaf, and the

also found in Sweden by Lindberg.
22. S. P o r to r ic e n s e , Hampe. Dicecious (?), very largo,
generally floating, the exposed portion greenish, the immersed
grayish brown ; stems solid, the cortical cells in 3 or 4 layers,
fibrillose and slightly porose; branches in fascicles of 4 or 5,
some ament-like, attenuate at base, erect or arcuate, others
longer, more slender and pendent: stem-leaves appendiculate
or suhstipulate, broadly triangular-ovate, entire, the utricles
without pores and with few fibrils; branch-leaves closely
imbricate, cucullate and scabrous on the back at the apex,
broadly ovate, obtuse, minutely fimbriate all around like the
stem-leaves, narrowly margined, the utricles fibrillose and
porose and with the walls made papillose by the bases of abortive
fibrils; ducts as in the last species: fruit unknown.—

§ 7. C y c lo ph y l la . Loosely cespitose: stems shorty with or
mostly without short simple ament-like branches: leaves
loosely imbricate, orbicular or ovate, broadly obtuse: ducts
central, oval, thick-walled: cortical cells large, in a single
layer. Plants generally destroyed by drought and annually
reproduced from the prothalhum.

very entire, with two rows of thin marginal cells, the utricles
long, flexuous, fibrillose, with minute pores along the borders;
pcrich®tial leaves ohlong-ovate, erose or truncate at the apex:
capsule globose, small, immersed in the lateral bud-like periohse-
tium : male aments upon short simple tufted branches. — Muse.

25. S. P itzg e ra ld i, Renauld, in Hit. Plants in short
compact whitish tufts; stems slender, with a single cortical
layer of large rectangular-elongated cellules; branches single or
two together, short, arcuate or pendent: stem-leaves oblong or
obovate, truncate and dentate at the apex, auricnlate at the base,
bordered h}’ two rows of very narrow cells ; the utricles fibrose,
without pores ; branch-leaves narrow, Unear-oblong, truncate,
denticulate at the apex and along the borders to the middle;
the marginal cells and utricles as in the stem-leaves; ducts
medial, nearly square, much smaller than the utricles, but free
on the lower and upper surface : flowers and fruit unknown.
Hab. Florida, on decaying leaves of palmetto (C. II. Fitzgerald).
Species allied to S. sedoides, Brid., differing in the stem-leaves, obovate
and auricnlate at base, those of the branches narrow, nearly linear, denticulate
to the middle, truncate at the apex, and in the small square free
intermediate ducts.
