Stem cortex in 1–3 layers, hyaline cells large, thin-walled, without fibrils, mostly porose; central cylinder yellowish brown. Stem leaves 1.0–1.8 mm × 0.8–1.0 mm, broadly ligulate to elliptic, concave, margins involute, borders differentiated; hyaline cells rarely divided, fibrillose, or sometimes indistinct, with a few small, ringed pores at the ends and corners on both surfaces. Branches in fascicles of 3–5, with 2–3 spreading. Branch leaves 1.5–2.2 mm × 0.8–1.2 mm, broadly ovate to elliptic, strongly concave, margins involute, borders narrowly differentiated, obtuse and denticulate at the apex; hyaline cells with a few, small pores at the corners on the ventral surface, with more ringed pores, often scattered at margins along commissural rows on the dorsal surface; green cells in cross section elliptic, centrally located, exposed equally on both surfaces.
