cells smallish, 4-, 5-, or 6-angled, walls thin, no trigones or thickened
angles. Stipules absent. Female flowers terminal on short lateral
branches ; bracts about twice as long as the leaves, broadly oblong,
slightly complicate, very shortly bilobed, postical lobe about twice
as narrow as the antical. Perianth emersed, turbinate or pyriform,
slightly compressed, acutely 5-angled, keel almost smooth,
sometimes furnished with a single series of pellucid cells. Calyptra
pyriform, texture similar to the leaves. Capsule subspherical,
hyaline, cleft halfway to the base. Androecia on short lateral
brandies, roundish or spicate ; perigonial bracts 3, 4 pairs, cymbi-
form, turgid. Antheridia single, oval.

South of Ireland.
Found on the Continent.
O b s . — Being destitute of stipules this plant is at once distinguished
from those British species which have them.
Lej. calcarea, Libert, and Lej. Bossettiana, Massai, have
ediinate leaves.
Lej. mioroscopica, Tayl. has more spreading, narrower leaves,
and is rarely found fertile.

Paroicous, loosely cæspitose, minute, very pale green to white.
Stems creeping, very slender, flexuose, pellucid, subramose ; radiculose,
rootlets few, distant, short, single, pellucid. Leaves often
unilateral, distant, patent, ovoideo-fusiform or ovate-lanceolate,
somewhat flattened, slightly unequally bilobed, antioal lobe a little
larger than the postical, apex subacute, triangular or shortly
liuguaform ; epidermis papillose, in some specimens almost smooth,
texture pellucid ; cells smallish, 4-, 5-, and 6-angled, walls thin, no
trigones or thickened angles, near the base in the middle elongate.
Stipules absent. Female flowers on short branches, bracts unequally
bilobed, antioal lobe narrower and longer than the leaves, ovate-
lanceolate, postical lobe much smaller, lanceolate acute. Perianth
pellucid, obovate or oboonical, papillose, ecarinate or obtusely
angled, apex flat, no beak, mouth contracted. Androecia on short
lateral branches, perigonial bracts bilobed, more obtuse at the apex
than in the leaves. Antheridia oval.
