Notes     (Last Modified On 5/4/2009)
general taxon notes:
This species is similar to Mnium carolinianum Anders. in general habit, leaf shapes and margins, and in having a row of enlarged cells in juxtacostael regions. Anderson (1954) stated that Mnium carolinianum is characterized by its concave leaf apices, thick-walled marginal leaf cells (2–3 rows of smaller cells), and decurrent leaf bases. These features are also found in Plagiomnium maximoviczii. We consider these to be sister species between East Asia and North America. Perhaps, they are one species with disjunctive distribution.
This species is also a host species of gall aphis, Schlechtendalia chinensis Bell. It is one of the main host species among eleven Mniaceae species.

Plants relatively small, in loose tufts. Primary stems prostrate, with dense brownish rhizoids; secondary stems erect, ca. 1.0–1.8 cm high, radiculose below, with leaves forming rosettes at the tips of stems; branches slender, from base of the stems, curved, 0.8–1.2 cm long. Leaves crisped when dry, spreading when moist, narrowed and slightly decurrent at base, abruptly acute, obtuse or apiculate at apex; margins distinctly bordered by 2–4 rows of obliquely elongate-rectangular cells below mid-leaf, upper margins not clearly bordered, serrate; costae percurrent; leaf cells rather small, irregularly rounded-hexagonal, walls slightly thickened at corners; basal cells rectangular, ca. 60 µm long, with a row of juxtacostael cells 2–4 times larger than adjacent cells, quadrate or pentagonal. Dioicous. Setae clustered, 1.5–3.5 cm long; capsules ovoid-cylindrical, ca. 2.8–4.0 mm × 1.2–1.8 mm, horizontal to pendulous; opercula conic, rostrate.
