Leaves iuoubous, contiguous or subimbricate, to the plica erecto-
patent, afterwards patent to patent-divergent, unequally bilobed,
antical lobe obliquely oblong or ovato-oblong, rotundate, slightly
concave, at the base subdecurrent, complicate, quite entire, plane,
postical lobe 3-7 times smaller, snbovate or rhomboid-quadrate,
saccate, margin inflexed, transverse or subascending, rarely obsolete.
Cells smallish, roundish-quadrate, 5- and 6-angled, near
base sliglitly elongate, walls and angles thickened, sometimes
trigones distinct. Stipules below smaller and distant, above
larger and contiguous, about half the length of the antioal lobe of
the leaf, about 3 times larger than the postical lobe, ovato-oval or
orbicular, bifid to tlie middle, sinus narrow, obtuse or acute,
segments suhobtuse or acute, sometimes one lobe acute, the other
shorter and obtuse, quite entire, rotundate at the base or cordate,
rarely decurrent. Female flowers terminal on the branches or on
stem, and subtended by a simple or repeatedly proliferous innovation,
or sometimes by a pair of opposite ones. Bracts much
longer than the leaves, complicato-bilobed, antical lobe oval-
lanceolate, obtuse, margin plane, quite entire, postical lobe about
half the size or still smaller, elliptical, obtuse. Bracteole oblong,
obovate, narrowly lanceolate or cuneato-lanceolate, cloven to about
the middle or deeper, sinus very narrow, segments obtuse.
Perianth very slightly emersed, green, pyriform, rounded at the
apex, beak short, slightly compressed, 5-oarinate, keels small,
suhobtuse. AndrcBcia on short lateral branches or on stem, rotund
or oval, perigonial bracts 5-9 pairs, bilobed to the middle, postical
lobe rather smaller than the antical, diandrous.

O b s .—Distinguished from Lej. serpgllifolia by the longer and
more narrowly ovate antical lobe, and the smaller postical lobe,
smaller cells with thicker walls and angles, and larger stipules.
“Lej. serpyllifolia is a smaller plant,colour more rarely yellowish,
leaves rounder and with a much longer and more turgid postical
lobe, sometimes equalling half the antical.” (E. Spruce.) Dr.
Carrington was the first to publish any notice of this species as
native to our Isles, when he described it as var. thymifolia of Lej.
serpyllifolia in his “ Irish Cryptogams.” Prof. Lindberg afterwards
published it as Tjey. Moorei, but later considered it along with
Dr. Spruce identical with Lej. flava (Sw.), which has a very wide
geographical distribution. Plants with perfect perianths are
extremely rare.

Monoicous, loosely creeping amongst mosses, largish, yellowish
or with a reddish tinge. Stems prostrate, fragile, rarely sub-
stratified, subpinnate; frequently the flower-bearing branchlets,
are elegantly pinrmlate. Leaves widely patent, distinctly
distichous or bent lightly backwards, dissitous or contiguous,
rarely subimbricate, subohlique, ovate-oblong or ovate, obtuse,
sometimes subaoute rarely rotundate, near the base subsinuate-
complioate; lobule very small, less than } the size of the leaf,
subovoid, inflated, with the apex either running gradually into
