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 triangular-lingulate to lingulate, 1.1–1.4 mm, apex broad-rounded to narrowly truncate, border very broad at base (more than 0.3 width);

hyaline cells efibrillose, rhombic, mostly 1-septate but can be non-septate.

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

long and tapering, usually strongly 5-ranked.

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, 0.9–1.4 mm, concave, straight, apex involute;

hyaline cells on convex surface with very small ringed pores (less than 0.25 cell width) along commissures near apex, changing abruptly to large elliptical pores (0.4 cell width or more) basally, concave surface with large round pores in proximal margins and leaf base.

often monoicous.
