denticulate. Bracts 2, patent, from a clasping base; bracteole
lanceolate, unidentate, free. Capsule ovate, coriaceous, 4-valved.

Coleochila Taylori, Dum. Hep. Eur. p. 106 (1874).
Dioicous, growing in dense, extensive patches, size medium
to large, of a yellowish or reddish-brown to a purple colour.
Stems simple or with one or two innovant branches arising from
axil of bracts, lateral, or slightly sub-postical, erect or suberect,
firm, flexuose, brownish ; cells of stem uniform, pale brown colour
throughout; very densely radiculose on the underside, rootlets
dull white, long, covering almost the whole of the underside of
the stem. Leaves bifarious, alternate, horizontal at an angle of
80° to 90°, obliquely semiamplexicaul, antioal base slightly decurrent,
contiguous or imbricate, secund, suborbicular, broadly ovate
or broadly oval, plane or slightly concave, margin entire, sometimes
slightly undulate, sometimes retuse; texture thick, sub-
carnose, epidermis with each cell convex and minutely verruculose,
cells largish, roundish, dull colour with the numerous chlorophyl
granules, walls hyaline, trigones distinct, roundish or angular.
Stipules small, subulate or lanceolate. Bracts no larger than the
leaves, somewhat similar in shape, entire, slightly spreading or
appressed. Bracteole free, broadly subulate. Perianth projecting
about half beyond the bracts, terminal, laterally subcompressed,
oblong-ovate, composed of one layer of cells, mouth contracted,
truncate, small, complánate, bilabiate, with about 15 club-shaped
irregular cilia, texture similar to the leaves, except near to the
mouth, wliere it is smooth and the cells more delicate, distinctly
verruculose in the middle and lower portion. Calyptra obovate,
4 cells thick at the base, at apex one, cells elongate, walls thin,
no trigones or angles thickened. Pedicel about inch long.
Capsule oval, dark reddish-brown. Spores pale brown. Elaters
hispiral, about 15 turns, dark reddish-brown.
Male stems distinct, usually smaller, perigonial bracts about
middle of stem, or terminal, suberect, semiamplexicaul, ventricose
almost lobulate, enclosing 1 or 2 spherical antheridia, with long
hearers.
