Flora of North America species comparison

leaves generally larger than branch leaves, 1.3– 1.8 × 0.8–1 mm;

elliptic to lingulate-spatulate, widest above middle, hyaline cells nonseptate.

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.

long-cylindrical, branch leaves terete to sometimes distinctly squarrose in shade forms.

more or less 5-ranked.

1–1.4 mm, ovate to ovate-lanceolate, gradually narrowed to an involute tip, hyaline cells somewhat bulging on concave surface and nearly plane on convex surface, with 4–8 large, elliptic, unringed pores per cell on convex surface and 1–4 irregularly rounded pores per cell on concave surface, internal commissural walls smooth to rather strongly papillose, chlorophyllous cells ovate-triangular with the widest part at or close to the convex surface.

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.

dioicous.
