Flora of North America species comparison

leaves triangular to triangular-lingulate, 1–1.3 mm, apex acute to slightly obtuse, border broad at base (more than 0.25 width);

hyaline cells narrowly rhomboid, mostly 0–1-septate and mostly efibrillose.

leaves lingulate to triangular-lingulate, 0.9–1.2 mm, apex rounded, usually 1/3–1/2 of leaf fibrillose;

hyaline cells usually fibrillose in distal 1/3–1/2 of leaf, on convex surface near apex with 1–3 pores per cell, on concave surface near apex 1–4 pores per cell.

usually strongly 5-ranked.

arched but rarely curved and contorted.

ovate to ovate-lanceolate, 1.1–1.5 mm, concave, straight, apex slightly involute;

hyaline cells on convex surface with numerous oval to elliptic pores along commissures grading from small pores near apex to large round pores at base, concave surface with large round pores in proximal portions of leaf.

ovate, 1–1.5 mm, straight to slightly subsecund;

hyaline cells of convex surface with numerous ringed pores along the commissures (12–22 per cell), 0–3 pores per cell on the concave surface.

monoicous or dioicous.

with few pseudostomata.
