Aplozia crenulata, Dum. Hep. Eu r. p. 57 (1874).
Dioicous, loosely cæspitose, flagelliferous, small, of a pale
green, rosy or reddish colour. Stems reddish-brown, procumbent,
cortical cells larger than the inner, whitish, 20 round, inner same
colour, 7 x 8 in diam. ; simple or innovantly branched, innovations
lateral, arising from axil of leaf, numerous, with small
distant leaves ; radiculose, rootlets dull white, plentiful, ascending
to apex of stems. Leaves on the upper portion of stem larger
and more crowded, imbricate, obliquely inserted, patent, secund
or spreading, lower leaves smaller and more distant; broadly
ovate to subrotnnd ; texture somewhat thin, epidermis smooth,
cells from smallish to small, roundish-quadrate, 4-, 5- and 6-
angled, near the base elongate ('0237 mm.), walls thick, trigones
very small or wanting, marginal cells largish ('053 mm.), oblong-
quadrate, which give the plant a very distinct appearance, margin
quite plane, not crenulate ; these large marginal cells are usually
wanting in the small leaves of the innovations. Stipules absent.
Bracts similar to the leaves, only larger, appressed, sometimes
produced from the lower part of the perianth, but very rarely.
Bracteole wanting or sometimes rudimentary, then lingulate.
Perianth terminal, projecting about ^ beyond the bracts, composed
of a single layer of cells, 130 round, larger at the angles,
obovate, slightly compressed, plicate, 4-angled, angles smooth or
irregular, obtuse or acute ; mouth contracted, submucronate,
fringed with hyaline, elongate cells, margin crenulate. Calyptra
thin, delicate. Pedicel long, pellucid, white, oross-section shows
17 cells round, 6 x 6 in diam. Capsule small, oval, dark reddishbrown,
spores pale reddish-brown, elaters reddish-brown. Male
stems smaller, slender, with several pairs of perigonial bracts,
small, closely imbricate, semi-amplexicaul, ventricose at base,
margin inflexed; antheridia 1 or 2, oval, pale green, bearers
short.
Pruits Winter and Spring.
