obtuse valves. Spores spherical, minutely tuberculate, 2 to 3
times broader than the unispiral, pale golden-brown elaters, also
.of a darker colour.
Male flowers on short lateral branches, catkins roundish or
elongate ; perigonial bracts 4-8 pairs, turgid, unequally bilobed,
antioal lobe oval, postical lobe rather smaller oval-quadrate,
perigonial bracteole oval-acute, bifid to about sinus acute, segments
acute ; antheridia globose.

Found on the Continent.
O bs.—Distinguished from other British FruUania by its proportionately
large postical lobes, when fertile by its tuberculate
perianth.

Plants conspicuous, somewhat large, dark green, prostrate,
substratified, dichotomous, or pinnately branched. Stem 8 cells
in diameter, about 32 in circumference. Leaves large, incubous,
bipartite: antioal lobe plane, dentato-spinose or ciliate; lobule
minute, saccate, rarely evolute lanceolate acuminate; cells small
or medium, subequal, walls delicate. Antioal elobulate leaf
axillary at the insertion of every branch, seated partly on the
stem and partly on the branch. Stipules half the size of leaf,
plane, subrotund, bifid, sparsely spinose or quite entire. Inflorescence
monoicous. ¥ innovations two opposite, rarely only one.
Bracts 1 pair, unequally complicate; bracteole bipartite, free.
