pale green to straw-colored;

superficial cortical with a large round pore in distal portion of cell free from cell wall.

green to brown;

superficial cortex of 2–3 layers of enlarged, thin-walled cells.

not 5-ranked, quite terete, long, and slender Branch fascicles with 1– 2 spreading and 1–2 pendent branches.

short and blunt, sometimes lacking completely and plants simplex.

spatulate to broad-spatulate, 0.8–1.5(–2) mm, strongly lacerate across the broad apex and often part way down the margins, border scarcely to strongly broadened at base (0.25 width of base or less);

apex rounded;

hyaline cells non-septate, convex surface with numerous small pores (less than or equal to 1/6 cell diameter) forming a continuous row along the commissures, concave surface aporose or with a few scattered pores along the commissures and cell ends.

ovate to ovate-lanceolate; 1.1–1.5(–2) mm, slightly concave, straight;

apex involute;

margins entire;

hyaline cells on convex surface with numerous pores along the commissures grading from small pores near leaf apex to large pores at base, concave surface with large round pores at leaf apex and along margins.

broadly ovate, 1.4–2.5(–3) mm; straight;

apex rounded;

hyaline cells as in stem leaf.
