Flora of North America species comparison

leaves to 2 × 0.7 mm; rarely hemiisophyllous;

hyaline cells non-ornamented, mostly nonseptate.

leaves narrowly to broadly lingulate or sometimes lingulate-spatulate, (1.1–)1.2–1.4(–1.6) mm;

apex broadly obtuse to obtuse-truncate and more or less fimbriate-lacerately resorbed, border in distal half narrow and often indistinct, in proximal half widened and filling up 1/3–1/2(–2/3) of the breadth at the base;

hyaline cells broadly S-shaped to rhombic S-shaped, predominantly nonseptate but a few cells are 1–3-septate;

efibrillose.

long and tapering to short and pointed, leaves loosely imbricate.

unranked, terete.

broadly ovate, to 2 × 1 mm or more wide, broadly ovate, hyaline cells non-ornamented, convex surface with round to elliptic pores along the commissures; chlorophyllous cells short-elliptic in transverse section and well-enclosed on both surfaces.

broadly lanceolate to ovate-lanceolate, (1.1–)1.4–1.8(–2.1) mm, slightly concave, straight to slightly subsecund;

apex involute;

border entire;

hyaline cells on convex surface with (5–)8–10(–12) semicircular to elliptical, ringed pores along the commissures, concave surface aporose or infrequently with 1–2 pores per cell in the distal portion of the cell, more numerous along leaf margins.

dioicous.

unknown.

with numerous pseudostomata.

22–30 µm; roughly papillose to nearly smooth, with distinct Y-mark sculpture on distal surface;

proximal laesura 0.5–0.8 spore radius.

not seen.

fascicles with 2–3 spreading and 2–3 pendent branches.;

branch stems with hyaline cells non-ornamented;

no or weak funnel-like projections on the interior end walls, large round pores on superficial cell walls.

fascicles with 2 spreading and 1 pendent branch.
