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 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.

terete.

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

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, 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.

dioicous.

ca. 31 µm, ornamented by small somewhat amalgamated granulae.

fascicles of 2 spreading and 1–2 hanging branches.;

branch stems with 1–2 layers of cortical cells.

fascicles with 2 spreading and 2–3 pendent branches.

unknown.
