(twice as long as broad) ; the fleshy perianth running to a narrow
point often quite closed, &c. The way some genera touch many
others, more or less closely, is very remarkable.”

Genus 18. EREMONOTUS, Lindb. fl- Kaalaas.
Diplophyttum, Carr, in Carr, et Pears. Hep. Brit. Exsioo. n. 96 (1879).
Jungermania, Carr, in Tran.s. Bot. Soc. Edinb. p. 166 (1880).
Hygrobiella, Spruce, On Cephalozia, p. 75 (1882).
Plants small, with the habit of Cephalozia dicaricata, reddisli-
or brownish-green, densely and intricately cæspitose. Stems very
rigid, comparatively thick, fragile, at the base leafless, slightly
radiculose, repeatedly ramose, most branches lateral or axillary,
below leafless, above leafy, eradiculose, a few (chiefly the lower
ones) postical, leafless, tiagelliferous and radiculose. Leaves sub-
transverse, lower ones distant, minute, appressed. upper gradually
larger and closer, ovato-quadrate, complicate, to the middle or
more acutely bifid, with acute segments; cells minute, subquadrate,
walls thickened. Stipules absent. Inflorescence dioicous.
Female flowers terminal on repeatedly innovant proliferous
lateral (very rarely postical) branches. Bracts distichous, 2-3 pairs,
innermost 3 to 4 times larger than the leaves, ovato-quadrate,
from i to ^ bifid, lobes obtuse, rotundate. Perianth free, uni-
stratose, relatively large, semiemersed, oblong, frontally compressed,
antical deeply unisulcate, postical bisuloate, with a smaller
obtuse keel between the furrows, apex broadly rotundate, mouth
small, minutely denticulate or setulose. Andrcecia situated at
the end or middle of branohes, amentiform ; perigonial bracts
monandrous, distichous, somewhat similar to the leaves, only
broader and more concave, bifid to about -J-, segments obtuse.
O b s .—This new genus differs from Cephalozia in its branches
being lateral, not postieal, and from Hygrobiella, which is its
nearest ally, by its frontally compressed, not distinctly trigonous
perianth, absence of stipules, bracts of the female flowers being
distichous and the very different cell structure ot the leaves.

Hygrobiella myriocarpa, Spruce, On Cephalozia, p. lb (1882).
Dioicous, densely cæspitose, small, of a reddish-brown colour.
Stems 3 to J inch long, creeping at the base, rhizomatous shoots
entangled, flexuose, resembling pale brown horsehair, terete,
ascending, rigid, interrupted, repeatedly innovant, branohes
springing from one or both sides of the old axis, either barren
and setaceous or fertile and with rapidly accrescent leaves, some
branches (upper) lateral, others (lower) postical flagelliferous and
rooting, rootlets sparse ; cells of stem 6 or 7 in diameter,
cortical 20, snbquadrate, very little larger than the inner ones, at
first large and pellucid, afterwards, when dry, opaque. Leaves
on tbe lower portion of stem and branches distichous, approximate,
erect, and appressed so close to the stem as to be readily
overlooked, ovate, ovate-quadrate, complicate, carinate-coiicave,
when explánate subcuneate, bifid to the middle, segments acute,
sinus acute, texture thin, chitinous, polished ; cells minute, punctate,
snbquadrate, leptodermous, subpelluoid. No stipules.
Flowers ¥ terminal, often on repeatedly innovant-proliferous
branohes, innovations lateral, rarely postical, sometimes two
opposite, elongate. Bracts for the size of the plant large, 2-3
pairs, distichous, closely conduplicate and equitant, keel at an
