general taxon notes:
Fissidens teysmannianus can be separated from the closely related species, F. taxifolius, by its leaf cells, especially those of vaginant laminae in which the hyaline, pearl-like papilla at each cell corner can be easily seen. Occasionally, the plants of F. teysmannianus have a few branches. The bases of dorsal laminae are variable in the Chinese specimens, and they are usually rounded, but sometimes are wedge-shaped to broadly wedge-shaped. Although the papillae of upper leaf cells are sometimes worn off (Iwatsuki & Suzuki 1982), they still can be seen on the cells of the vaginant laminae.

49. Fissidens teysmannianus Dozy & Molk. 南京凤尾藓 nan-jing feng-wei xian
Pl. Jungh. 317. 1854. Type. Indonesia: Java, Teysmann s.n. (lectotype designated here, L).
Fissidens adelphinus Besch., Ann. Sci. Nat. Bot., sér. 7, 17: 354. 1983, syn. nov. Type. Japan: U. Faurie 197 (lectotype PC; isolectotypes H-BR, KYO).
Fissidens nankingensis Broth. & Par., Rev. Bryol. 37: 1. 1910. Type. China: Nanking (Nanjing), Schenkiang, D. P. Courtois s.n., Feb. 1909 (lectotype H-BR).
Plants medium-sized for the genus. Female leafy stems simple to sparsely branched, reaching 3 cm or more in length, ca. 3 mm wide; axillary hyaline nodules not differentiated; cortical stem cells small, thick-walled; central strand not differentiated. Leaves often more than 50 pairs, more or less densely arranged; mature leaves lanceolate, 1.50–2.25 mm × 0.35–0.50 mm, acute at apex, base of dorsal laminae round, not decurrent; vaginant laminae about one half of leaf length; costa stout, percurrent; margins crenulate throughout; cells of apical laminae round-hexagonal to round-quadrate, 7–10 µm long, mammillose, often with an indistinct papilla at each corner; cells of vaginant laminae similar to those of apical laminae, but slightly larger, less mammillose, with more distinct papilla at each corner. Dioicous. Male plants smaller than female plants, about 10 mm long, 3 mm wide with leaves; antheridia in axils of basal to upper leaves of male plants, bud shaped, about 0.4 mm long; archegonia also in axils of basal to upper leaves of female plants, 0.6–1.0 mm long.
