Notes     (Last Modified On 3/11/2009)
general taxon notes:
 
Although the sexuality and the location of gametangia are quite stable in this variety, the plant sizes and the forms of leaf shape and sporophytes are variable. This variability may cause confusion with other species. The variety is characterized by having the central strand slightly differentiated, the base of dorsal laminae wedge-shaped and ending at the base, and by having differentiated borders nearly reaching to leaf apex.

Plants small. Leafy stems usually simple, rarely with innovations from leaf axils, 1.5–5.6 mm long, 1.3–2.4 mm wide; axillary hyaline nodules not distinctly differentiated; central strand weakly differentiated. Leaves in 4–6 pairs, upper leaves oblong-lanceolate, 0.8–2.0 mm × 0.3–0.5 mm, acute at apex; base of dorsal laminae wedge-shaped; costa percurrent or ending a few cells below leaf apex; vaginant laminae ca. 1/23/5 the leaf length, usually more or less unequal; limbidia usually strong, 1–3 rows of cells on apical laminae, 3–6 on vaginant laminae, in cross section 1–3 cells thick; cells of apical and dorsal laminae quadrate to hexagonal, 5–12 µm long, moderately thick-walled, smooth; cells of vaginant laminae similar to those of apical and dorsal laminae, but larger and longer toward the base near the costa. Autoicous. Male inflorescences bud-like in axils of stem leaves. Female inflorescences terminal on stems; archegonia ca. 245 µm long. Perchaetial leaves similar to stem leaves, but somewhat larger. Setae 1.8–7.5 mm long, smooth; capsules symmetrical; urns 0.25–0.80 mm long; opercula conic, rostrate, 0.35–0.60 mm long; exothecial cells rectangular, with longitudinal, moderately thick walls.

 The Fissidens bryoides complex is very variable. Five varieties of Fissidens bryoides have been reported from China. It is quite difficult to identify these varieties, especially when only vegetative plants are present since the classification of the complex is mainly based on the sexuality and distribution of gametangia rather than on the types of limbidia (Iwatsuki & Suzuki 1982).

 
1. Cells of apical laminae small, 4–10 µm long, mammillose; dioicous...................................... 5e. var. schmidii
1. Cells of apical laminae large, 7–14(–17) µm long, smooth (but occasionally more or less mammillose);. monoicous.......................................................................................................................................2
2. Female inflorescences (and setae) mostly lateral, rarely terminal; perichaetial leaves of lateral inflorescences much smaller than stem leaves.................................................................... 5c. var. lateralis
2. Female inflorescences (and setae) always terminal; perichaetial leaves not well differentiated.............. 3
3. Central strand weakly differentiated; autoicous; male inflorescences bud-like (rarely naked) found in axils of stem leaves............................................................................................................................... 5a. var. bryoides
3. Central strand lacking; synoicous (often polyoicous) or rhizoautoicous; male inflorescences otherwise.... 4
4. Rhizoautoicous; male inflorescences usually bud-like at the base of female stems; sterile female and male stems often connected at their bases........................................................................................ 5b. var. esquirolii
4. Synoicous, often polyoicous; antheridia mixed with archegonia terminal on stems or branches, but often bud-like found in leaf axils (rarely at base of branches); sometimes several female branches mixed with a few perigonia in the same leaf axil..................................................................................... 5d. var. ramosissimus
