Stem leaves 1.3–1.4 mm × ca. 1 mm, ligulate, rounded obtuse, dentate or lacerate at the apex; borders hyaline, cells indistinctly differentiated; hyaline cells usually undivided, without fibrils and pores, or rarely with the traces of fibrils and membrane gaps. Branches in fascicles of 5, with 2–3 spreading. Branch leaves 1.2–1.6 mm × 0.6–1.0 mm, ovate-lanceolate, gradually narrowed to a sharp acumen, reflexed in the upper part, margins involute; hyaline cells rhomboidal, fibrillose, with large, ringed pores at the corners of upper cells, gradually positioned along commissural rows in the lower cells on the ventral surface; with a few large, non-ringed pores at the upper corners, gradually becoming numerous rounded, ringed pores near the base on the dorsal surface; inner walls adjacent to green cells often faintly papillose; green cells in cross section trapezoidal, exposed more broadly on the dorsal surface, slightly exposed or largely enclosed by hyaline cells on the ventral surface.
