Trinity sphagnum
|
common red peat-moss, small red peat moss, sphagnum
|
| Plants moderate-sized, slender and weak-stemmed, green to pale yellow; flaccid and plumose in aquatic forms to more compact and sprawling in emergent forms; green to pale yellow; capitulum not especially enlarged and differentiated. |
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. |
leaves ovate-triangular to triangular, 1–1.6 mm; appressed to spreading; apex acute to slightly obtuse; hyaline cells often fibrillose and often 1-septate. |
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. |
straight and unranked, in capitulum tapering at distal end to a point, leaves greatly elongated at distal end. |
not 5-ranked, terete. |
ovate-lanceolate to lanceolate, 2–3.5 mm; straight, undulate and slightly recurved when dry; margin serrulate; hyaline cells on convex surface with 0–1 small pores at cell apex on concave surface with round wall thinnings in cell angles (often indistinct or lacking); chlorophyllous cells trapezoidal in transverse section and exposed more broadly on the convex surface. |
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. |
monoicous. |
dioicous. |
26–40 µm; ± roughly to densely granulose. |
20–28 µm; finely papillose on both surfaces, with distinct raised Y-shaped sculpture on distal surface; proximal laesura 0.5 spore radius or more. |
stems green, cortex enlarged with conspicuous retort cells. |
fascicles with 2 spreading and 1–2 pendent branches. |

Sporophytes are common in Sphagnum trinitense, which can often be distinguished from S. cuspidatum in the field by the appearance of its branches when wet. In this state the branches of S. trinitense just below the capitulum resemble a fine paintbrush drawn out to a pointed tip. See also discussion under 29. S. fitzgeraldii and 39. S. mississippiense. Spore features are taken from H. A. Crum (1984). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.) |
