flowers monogynous. Innovations sub-floral, solitary,
or binate and opposite, in most species
adnate to the bracts, in others absent. Bracts
one, rarely many jugate. Pedicel almost the same
as in Jubula; axial cells 4-seriate, peripherical
i2-i6-seriate. Capsule with the inner face
spongy.
The genus Lejeunia, as recognized by Spruce,
contains all the strictly monogynous Jubuleæ, and
is well distinguished from Frullania by (i) the
branches being contiguous to the outer base of
the leaves, i.e., infra-axillary ; (2) the usually
rhomboidal or ovate lobule being either plain or
ventricose, but never (as in Frullanid) either
o-aleate or inversely saccate-shaped, like a bell, or
a glove finger— except in the very rare case of
L. calyptrijolia, and three or four allied tropical
species, where the lobule is lengthened out into
the shape of a hollow horn or club ; (3) the monogynous
female flowers ; (4) the innovations, where
present, being adnate to the female bracts ; (s) the
pedicel cruciate on the section, only four cells
(not eight) across, quasi-articulate when dry, and
mostly geniculate at the joints. In addition to
the foregoing. Spruce also gives, in the work
already alluded to, valuable notes on the species
of Lejeunia, which are remarkably common in
tropical countries. For a local Flora it is wholly
unnecessary to follow him into his divisions of this
large tropical genus, into subgenera. Although
admitting Colura, and Phragmiconta, as subgenera
of Lejeunia, he also confesses that hereafter some
may consider them entitled to rank as genera,
with the residue of his temporary subgenera.
