Habit | Plants small to moderate-sized, slender, fairly stiff but soft, capitulum flat-topped and stellate; deep maroon-red to variegated red and yellowish green, lacking metallic sheen when dry. | Plants compact, short-branched and small; strongly reddish to golden brown, glossy when dry; flat-topped capitulum with moderately differentiated terminal bud. |
Stem(s) | leaves lingulate-triangular to lingulate, 1–1.4 mm, apex broadly rounded but becoming acute in hemiisophyllous forms, border strongly developed at base (more than 0.25 width); hyaline cells rhombic and 0–3-septate with some cells in leaf midregion 2–septate. |
leaves lingulate,small, equal to or less than 0.8 mm, appressed to stem; apex with strong lacerate split in the middle; hyaline cells efibrillose, aporose, and nonseptate. |
Branches | weakly to strongly 5-ranked. |
strongly 5-ranked, short and blunt, not much elongated at distal end. |
Branch leaves | ovate to ovate-lanceolate, 0.9–1.2 mm, concave, subsecund on some branches, apex involute; hyaline cells on convex surface with numerous round to elliptic pores along the commissures, grading from small round pores near apex to round pores near base, on concave surface with large round pores in proximal portions of leaf. |
ovate; usually less than 1.5 mm; stiff and slightly reflexed, straight to slightly subsecund; margins entire; hyaline cells moderately long and narrow (6–8:1), convex surface with one small round pore per cell at apex and numerous pseudopores on the margin, concave surface with large round wall thinnings in the cell angles and ends; chlorophyllous cells triangular in transverse section, with apex reaching concave surface. |
Sexual condition | dioicous. |
unknown. |
Spores | 18–33 µm, coarsely papillose on both surfaces; proximal laesura less than 0.4 spore radius. |
not seen. |
Branch | fascicles with 2 spreading and 1–2 pendent branches. |
fascicles with 2 spreading and 2–3 pendent branches.; branch stems green, with cortex enlarged with retort cells. |

Discussion | Sporophytes are uncommon in Sphagnum rubellum. This common species is associated with S. angustifolium, S. capillifolium, S. fallax, S. fuscum, S. magellanicum, S. papillosum, S. recurvum, and S. tenellum. Inland, it has a greater tendency to form extensive carpets and floating mats than hummocks. See also discussion under 65. S. andersonianum, 68. S. bartlettianum, and 86. S. talbotianum.

Sporophytes are rare in Sphagnum lenense. This species is easily distinguished from the similar S. lindbergii by its compact growth form and reddish brown color. Sphagnum lenense also is a hummock former in the tundra whereas S. lindbergii forms carpets. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
