Flora of North America species comparison

leaves broadly triangular-lingulate, 1.15–1.25 × 0.8 mm, apex slightly to broadly obtuse, border moderately broadened at base;

hyaline cells mostly 1-septate with a few to many 2-septate in the mid region, shape rhomboid.

leaves broadly lingulate-spathulate to spatulate, widest at base and/or distal third, usually narrower in the mid region, 1–1.3 mm, apex narrowly to broadly truncate and ± fimbriate-lacerate, border narrow distally and expanded proximally to 0.25 width or more;

hyaline cells efibrillose, irregularly rhombic to subquadrate, many cells 2–4-septate.

more or less 5-ranked.

unranked.

1.2–1.3 × 0.65–0.75 mm, broadly ovate, apex involute;

hyaline cells on convex surface with numerous round to elliptic pores along the commissures, these grading from small pores at the apex to large pores at the base;

concave surface aporose except for a few large pores in the lower side regions.

ovate-lanceolate, 1.1–1.4 mm, slightly concave, straight, apex involute;

hyaline cells on convex surface grading from aporose to few small round pores near apex to numerous semi-elliptic pores along commissures in middle and base of leaf, concave surface with a few large irregular to circular pores (1–4) occupying most of the cell width.

dioicous.

autoicous.
