Flora of North America species comparison

leaves 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);

hyaline cells rhomboid, efibrillose and often 1–2-septate.

leaves lingulate, 0.8–1.3 mm;

apex broadly rounded and entire to lacerate, sometimes slightly mucronate or slightly denticulate;

hyaline cells rhombic, 0–1(–2)-septate, usually efibrillose.

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

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.

ovate-lanceolate, 1.1–1.3 mm, straight, concave, apex strongly involute;

margins entire, hyaline cells on convex surface with round to elliptic pores along the commissures, grading from small pores near the leaf apex to large pores near the base, concave surface with large round pores in proximal marginal regions of leaf.
