general taxon notes:
Brotherus (1925) placed Rozea in the Entodontaceae. However, P.-C. Chen et al. (1978) considered Rozea to be closely related to Juratzkaea based on its leaves with slender costa, leaf cells elongate-rhomboidal and double peristome teeth; thus they placed it in the Fabroniaceae. Four species of Rozea from China were reported: R. diversifolia Broth., R. microcarpa Broth. (= R. fulva C. Müll. ex Fleisch.), R. myura Herz. [= R. pterogonioides (Harv.) Jaeg.], and R. pterogonioides. Crosby et al. (2000) recognized six species of Rozea in the world with five well understood. In this treatment, we recognized three species.

Mém. Soc. Sci. Nat. Cherbourg 16: 241. 1872.
 
Plants slender or somewhat robust, delicate, green, light yellowish green or reddish brown, glossy, in small patches. Stems creeping, forkedly or caespitosely branched; branches dense, erect or erecto-patent, obtuse at apex; central strand absent; pseudoparaphyllia foliose. Leaves imbricate when dry, sometimes slightly secund, erect or erecto-patent, elliptic-ovate or widely ovate-lanceolate, concave, longitudinally plicate, shortly acute or long acuminate at apex; margins revolute, toothed near the apex; costa single, vanishing in the middle of leaf; leaf cells oblong-elliptic or narrowly rhomboidal, mostly smooth, rarely papillose or projecting; basal cells short, loosely arranged; alar cells quadrate or flat quadrate. Autoicous or dioicous. Inner perichaetial leaves light green, widely lanceolate, piliferous at apex; costa short. Setae slender, erect, reddish; capsules erect, cylindrical, reddish brown, apophysis short; opercula conic, with a short beak; annuli absent; peristome double; exostome teeth lanceolate, yellowish, with zig-zag median line, densely striolate, distinctly trabeculate on inner surfaces; endostome segments light yellow, narrowly lanceolate, as long as exostome teeth, folded, smooth; basal membrane low, rarely high; cilia short, weak. Spores spherical, small.
