Flora of North America species comparison

(1–)4–5(–10) cm, simple, brownish tomentose only near the base.

2–6(–10) cm, simple or more commonly fasciculately branched, whitish tomentose only at base.

3–6(–8) mm, densely imbricate, ± erect and almost straight when dry, erect-spreading to widely spreading when moist;

sheath oblong-rectangular, yellowish, tapering to the blade;

blade slender, bluish green and nitid, rather flat, with sharply infolded margins;

marginal lamina 5–7 cells wide, 1-stratose, entire or minutely crenulate, membranous and transparent, enclosing the lamellae and overlapping towards the apex;

costa usually somewhat toothed distally, excurrent, forming a subulate, toothed awn, the awn reddish brown throughout or slightly decolorate at tip;

lamellae bluntly crenate in profile, 6–8 cells high, the marginal cells in cross-section ovate to pyriform, thick-walled, ending in a distinct knob, smooth or rarely faintly papillose, the marginal cells of lateral lamellae (enclosed by the overlapping margins) ovoid and less strongly thickened;

sheath cells 70–100 × 6–10 µm, narrowly rectangular (4–6:1), narrower toward the margin;

cells of the broad marginal lamina transversely elongate, very thick-walled.

3–6 mm, crowded in distal half stem, erect and closely appressed when dry, erect-spreading when moist;

sheath rectangular, abruptly contracted to the blade;

blade linear-lanceolate, rather flat, with sharply infolded margins, channeled at the apex and tapering to the bicolored awn;

marginal lamina 7–9 cells wide, 1-stratose, entire, membranous, infolded and overlapping, completely enclosing the lamellae;

costa excurrent with low blunt teeth abaxially near apex, the awn coarsely spinulose at the base, brown in the basal 1/3 to 1/2, hyaline distally;

lamellae 5–9 cells high, the marginal cells in section ovoid, somewhat larger than cells below, thin-walled or very slightly thickened at apex;

median sheath cells 45–90 × 12–15 µm, narrowly rectangular, thin-walled;

cells of marginal lamina 10–15 × 24–45 µm, thick-walled, obliquely oriented and shorter toward the margin and thin-walled.

(1–)3–5 cm, stout, yellowish to reddish brown.

rather short for plant size, 1.2–3 cm, reddish.

dioicous;

perigonial rosettes yellowish to reddish green;

perichaetial leaves longer than the foliage leaves, long-sheathing, the blade almost obsolete, ending in a slender yellowish or hyaline awn.

dioicous;

perichaetial leaves elongate, with hyaline lamina and long, tapering awn.

2.5–5 mm, rectangular, longer than wide (1.5–2:1), reddish brown to dark brown, glaucous when fresh, suberect, becoming horizontal when mature, sharply 4-angled and prismatic;

peristome 200–240 µm, divided to 0.6–0.8, the teeth 64, keeled at back.

2.3–3 mm, ovoid-rectangular (1.2–2:1), somewhat broader at base, sharply 4(–5)-angled, erect, becoming inclined to horizontal when mature;

peristome 150–230 µm, divided to 0.6, the teeth pale brownish, acute.

whitish to light brown, covering the capsule.

6–10(–12) µm.

15–17 µm.
