Me (REVUE BRYOLOGIQUE 
Robust, brownish or yellowish green. Stem 10 cm. long, 1 mm. 
in diameter, tripinnate or irregularly quadripinnate, the principal : 
branches 2 em. long, the remaining branches diminishing in size 
according to their rank, sometimes slightly tapering but never : 
attenuated into flagella. Stem-leaves contiguous, indistinctly com- 
plicate, broadly elliptical to rectangular in general outline, 1.2 mm. 
long, 1.7 mm. wide, divided to the middle or less into five or six. 
triangular or subulate, long-acuminate divisions, the two or three 
antical divisions being larger than the others ; margin everywhere. 
closely and irregularly ciliate, each cilium consisting of from two 
to four long cells in a single row, similar to the apical points of. 
the divisions but usually a little shorter ; margin often developing, 
close to the antical base, one to three small supplementary lobes. 
bearing marginal cilia similar to those just described ; outer sur 
_ face of leaf, except close to the base, bearing numerous scattered | 
_ cilia similar to the marginal cilia, and acquiring thereby a spongy 
._ appearance; cilia especially abundant on the postical divisions; 
inner surface of leaf perfectly smooth. Cells of stem-leaves avera- 
ging 23 X 18, rather thickwalled; trigones large but often con-. 
fluent and indistinct. Underleaves of stem rectangular-ovate in 
_ outline, 4 mm. long, 0 7 mm. wide, bifid two thirds or more; 
divisions triangular, lipped with a long eilium and bearing a small … 
supplementary lobe near the base; margin reflexed near the base | 
and at the bottom of the sinus, ciliate as in the leaves; postical 
surface also ciliate. Leaves of the primary branches subquadrate, 
0.9 mm. long, mostly quadrifid, the two antical lobes larger than 
= the postical; margin and surface as in the stem-leaves. Under 
leaves of the primary branches 0.7 mm. long, 0.5 mm. wide 
more deeply bifid than those of the stem, otherwise similar. Leaves | 
of the secondary branches subquadrate, 0.7 mm. long, abruptl 
_ broadening from a narrow base, mostly quadrifid, the most pos 
tical division occasionally developed into a small and smoot 
galeate sac. Underleaves of the secondary branches 0.5 mm. long 
0.4 mm. wide, deeply bifid. Leaves of the tertiary and quartenar 
branches 0.5 mm. long, 0.4 mm wide, quadrifid or trifid, th 
most postical division frequently developed into a sac. Correspon- 
ding underleaves 0.35 mm. long, 0.25 mm. wide. Cells of th 
_branch-lcaves averaging 35 X 16 x, with slightly and uniforml: 
= thickened wälls. Inflorescence dioicous : à inflorescence borne 
_a very short branch. Involueral leaves similar to the stem-lea 
but more symmetrical, with fewer and more slender divisions an 
with fewer cilia, Remaining parts unknown.
