| Plants small to moderate-sized, compact to fairly slender, normally stiff and erect; capitulum typically hemispherical; in exposed sites red, mottled red and green, in shaded sites green forms are common; without metallic lustre when dry. |
Plants moderate-sized, green in the shade to variegated yellow or orange or both in open habitats; capitulum typically rounded. |
green to red; superficial cortical cells aporose Stem leaves lingulate-triangular, 1.2–1.6(–1.8) mm, apex ± involute; border entire and broadened to about 0.25 the width of the base; hyaline cells S-shaped, 0–1-septate, usually fibrillose in distal portion of leaf. |
leaves lingulate to triangular-lingulate, 0.9–1.2 mm, apex rounded, usually 1/3–1/2 of leaf fibrillose; hyaline cells usually fibrillose in distal 1/3–1/2 of leaf, on convex surface near apex with 1–3 pores per cell, on concave surface near apex 1–4 pores per cell. |
not 5-ranked, terete. |
arched but rarely curved and contorted. |
ovate-lanceolate, 1–1.4 mm, imbricate to moderately spreading, concave, straight, strongly involute near apex; hyaline cells on convex surface with elliptic pores along commissures, concave surface with large round pores away from commissures in proximal portions of leaf. |

Sporophytes are fairly common in Sphagnum capillifolium. This species is most common and abundant in ombrotrophic heath vegetation associated with S. angustifolium, S. fallax, S. fuscum, S. magellanicum, S. rubellum, Polytrichum commune, and P. juniperinum. It can be distinguished from most other red species of sect. Acutifolia with which it co-occurs by its lack of 5-ranking in the branches. Sphagnum subtile is a forest and non-hummock forming species that has a distinctly shorter and more triangular-lingulate stem leaf. The stem leaf border on S. subtile is also more strongly bordered. Sphagnum tenerum, which geographically overlaps S. capillifolium only very minimally, has much more turgid branches and a generally more robust look. The stem leaf of S. tenerum is triangular-lingulate as compared to the lingulate- triangular stem leaf of S. capillifolium. See also discussion under 84. S. subnitens and 87. S. tenerum. The names Sphagnum acutifolium Schrader and S. nemoreum Scopoli (doubtful name) have also been used for this taxon. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
The sporophytes of Sphagnum inundatum are uncommon. The ovate, concave branch leaves that are occasionally subsecund give this species an appearance similar to that of S. subsecundum, from which it can usually be distinguished by its larger size. Sphagnum lescurii typically has distinctly larger stem leaves and capitulum branches that can be quite turgid and curved in open-grown forms. The names Sphagnum bavaricum Warnstorf and S. bushii Warnstorf & Cardot have been applied to this taxon. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
