resembling small forms of Geocalyæ gmveolens, but if their origin,
or connection with mature plants be traced, the difficulty is
solved.
This and the previous species have the strong unpleasant
smell, more evident when drying, of L. hidetitata.

Lophocolea spicata, Taylor in G.L.N. Syn. Hep. 107 (1844).
Monoicous, closely appressed to rooks, in entangled masses,
small, pale green in colour. Stems creeping, irregularly branched,
outer layer of cells large, hyaline ; radiculose, rootlets few, small,
whitish. Leaves gradually increasing and decreasing in size,
horizontal (90°) to patent-divergent (70°), slightly imbricating,
antioal margin decurrent, ovate, diversiform, hi-, tri or rarely multi-
dentate, segments acute, connivent or divergent ; texture delicate ;
cells small, snbquadrate or oblong-quadrate, 4-, 5- or 6-sided ;
walls moderately thick, no trigones. Stipules free, bipartite,
segments acuminate, unidentate near the base of the exterior
margins.
Involucres on short branches ; bracts oblong, upper portion
irregularly dentate ; bracteole bipartite, segments acutate, irregularly
dentate. Perianth projecting beyond the bracts, triquetrous,
angles not winged, month wide, laciniate-dentate; pistillidia
about 10. Calyptra after rupture irregularly lobed. Capsule
oval; spores light brown ; elaters bispiral, hardly as broad as the
spores. Male amentula on short branohes above or below the
2-5 pairs of perigonial bracts which are closely imbricate, ovate,
complicate, swollen at the base ; antheridia single, oval, shortly
stipitate. Mixed with the plants are many minute leafy
branohes.
Fruits April, May.
