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 appressed to stem or somewhat spreading; lingulate, ovate, to triangular; equal to or less than 0.9 mm;

apex obtuse and often erose to lacerate.

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

with leaves unranked to 5-ranked, leaves not much elongated at distal branch tip.

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, 1.1–1.3 mm long, stiff, weakly undulate and slightly recurved when dry;

hyaline cells in mid region quite short and broad, 3.3–2.5:1, in basal 1/2 of leaf on convex surface often with 1 large pore apically and/or up to 6 free pores, in apical region often with pseudopores along the cell margins;

on concave surface with large round wall-thinnings in the cell ends and angles (these sometimes faint or absent);

chlorophyllose cells triangular in transverse section and typically well-enclosed on concave surface.

often monoicous.

20–27 µm, finely papillose on both surfaces;

proximal laesura less than 0.5 spore radius.

fascicles with 2 spreading and 2–3 pendent branches.

unknown.
