Protliallium slender, linear or almost filiform, consisting of 

 only a single (more rarely in part of a double) series of cells ; 

 either simple or subramose ; often passing at the apex insensibl}^ 

 into the stem and persisting a long time. Plants usually small 

 and tender, in only a few species rather robust ; of almost all 

 shades of green and brown, or whitish and pellucid, sometimes 

 tinged with rose ; growing in depressed matted tufts, or flakes, or 

 creeping over Sphagna and other mosses. Stems usually prostrate 

 or procumbent, leafy throughout, or rhizomatous and leafless at 

 the base — very rarely with the leaves reduced to mere scales — 

 still more rarely frondose ; branches all postical, springing from 

 the underside of the stem, and axillary to the stipules where any 

 exist ; radicles usually copious, pale and slender. Leaves mostly 

 succubous, in a few species transverse, in a very few subincubous ; 

 horizontal or assurgent, never deflexed, roundish, or subquadrate, 

 or cuneate, rarely lanceolate, very seldom plane, usually concave.
