Flora of North America species comparison

leaves generally longer than branch leaves, 1.1–1.7 mm, lingulate to lingulate-spathulate, hyaline cells mostly non-septate.

leaves broadly oblong-triangular, 1.2–1.5 mm; mostly appressed to stem;

apex obtuse;

hyaline cells narrow, usually nonseptate, efibrillose and aporose on convex surface near apex, on concave surface usually efibrillose with irregular pores along commissures in distal portion of leaf.

terete.

with loosely imbricate leaves; often 5-ranked;

leaves little to somewhat elongated at distal end.

1–1.4 mm, broadly ovate, with a narrow involute tip;

hyaline cells only slightly bulging on either surface, in proximal half of leaf aporose on convex surface and with large faint pores on concave surface;

internal commissural walls distinctly papillose; chlorophyllous cells elliptical to elliptical-triangular in transverse section, enclosed on both surfaces with the widest part in the leaf middle.

ovate, ovate-lanceolate to lanceolate; 2–3.5 mm;

flat and undulate at margins and recurved at apex when dry; straight;

margins entire;

hyaline cells on concave surface with very numerous, small ringed or unringed pores along the commissures, 5–12 in distal portion of leaf and 20–27 in proximal portion, convex surface with 5–15 pores per cell in distal portion of leaf and 14–21 in proximal portion, pores usually without a ring; chlorophyllous cells triangular to trapezoidal in transverse section and exposed slightly on concave surface.
