9. DICNEMON, Schwmgr. 
Creeping tufted mosses, with short erect curved branches, growing on trees. 
Leaves imbricate all round the stems. Fruitstalk terminal on very short 
lateral branchlets, clothed by the long perichaetial leaves which partially hide 
the capsule also. Capsule elongate, oblique, inclined ; teeth 16, in one row, 
2-fid to below the middle, the divisions tubercled, incurved. Operculum 
with a slender oblique beak. Calyptra large, cucullate, rough at the apex, 
inflated when young. 
A genus generally associated with Leucodon, but according to Wilson most clearly allied 
to Dicranwn, and differing chiefly in the creeping habit.

10. LEUCOBEYUM, Hampe. 
Father large, tufted, white, stout, perennial, monoecious mosses, growing in 
wet ground, in woods, and on trunks of trees. Leaves spongy, nerveless, 
glaucous, cells perforated. Fruitstalk terminal, but apparently lateral. 
Capsule cernuous, strumous, grooved when dry; annulus 0; teeth 16, in 
one row, subulate, transversely barred, 2-fid at the apex, rough externally. 
Operculum long-beaked. Calyptra inflated, cucullate, long-beaked. 
A considerable tropical genus, rare in temperate regions, remarkable for its white colour, 
and the spongy texture of the leaves, which are formed of two layers of cells.
