1a. Homalia trichomanoides var. trichomanoides 扁枝藓原变种 bian zhi xian yuan bian zhong
Plants medium-sized, yellowish green, distinctly glossy, in complanate mats. Primary stems thin, creeping; secondary stems irregularly branched, sometimes simple; cross section nearly rounded, epidermis consisting of 2–4 layers of small, thick-walled cells; branches short, blunt at the apex. Stem leaves ovate, oblong-ovate, spathulate, asymmetrical, slightly arcuate, obtuse, rounded, or broadly acute, apiculate, narrowed toward the base; leaf margins serrulate at the apex, often narrowly incurved along the proximal side at base; costae slender, reaching about mid-leaf, rarely forked; upper leaf cells nearly rounded-quadrate, rhombic, 6–12 µm in diameter; median cells elongate, rhomboidal to oblong-rhomboidal, 30–40 µm × 8–12 µm, thick-walled; basal juxtacostal cells linear-rhomboidal, thinner-walled, hyaline; branch leaves similar to the stem leaves, smaller. Autoicous. Inner perichaetial leaves oblong, more or less sheathing at the base, narrowly lanceolate at the apex. Setae smooth, up to 1 cm long; capsules erect, oblong-cylindrical; opercula long rostrate; annuli differentiated; peristome double; exostome teeth lightly yellow, lanceolate, densely striolate below, papillose above; endostome segments as long as the exostome teeth, finely papillose, perforate; cilia developed, 1–2, sometimes rudimentary and fugacious. Spores 11–14 µm in diameter, faintly to rather distinctly papillose.
