Flora of North America species comparison

leaves triangular-lingulate, 0.8–1.4 mm, spreading to appressed;

apex acute to narrowly obtuse, hyaline cells nonseptate and fibrillose near apex.

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.

unranked or weakly 5-ranked, straight to strongly curved, leaves moderately elongated at distal end.

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

ovate-lanceolate to narrowly ovate-lanceolate, 1.8–3.4 mm; straight to strongly subsecund; weakly undulate and recurved when dry;

margins entire;

hyaline cells on convex surface with 1–2 free pores per fibril interval, concave surface aporose or rarely with a few wall thinnings in cell ends and angles; chlorophyllous cells trapezoidal in transverse section and narrowly exposed on concave surface.

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.
