|
|
Habit | Plants moderate-sized to robust, strong-stemmed, lax to somewhat compact, capitulum somewhat flattened to more typically compact and rounded; green to golden brown to pale brown with often a pinkish tinge; carpets to more or less compact, low to moderate sized hummocks. | Plants small and weak-stemmed; grows sprawling in lawns; pale brown to golden brown; capitulum flat-topped and only weakly 5-radiate. |
Stem(s) | leaves to 1.7 × 1 mm, occasionally longer; rarely hemiisophyllous; hyaline cells non-ornamented, nonseptate. |
leaves appressed to stem or somewhat spreading; lingulate, ovate, to triangular; equal to or less than 0.9 mm; apex obtuse and often erose to lacerate. |
Branches | long and tapering, leaves ± imbricate to spreading in shade forms. |
with leaves unranked to 5-ranked, leaves not much elongated at distal branch tip. |
Branch leaves | broadly ovate, 2.2 × 1.3 mm, hyaline cells non-ornamented, convex surface with elliptic pores along the commissures, chlorophyllous cells isosceles-triangular to ovate-triangular in transverse section and just enclosed to just exposed on the convex surface; end wall not thickened. |
ovate, 1.1–1.3 mm long, stiff, weakly undulate and slightly recurved when dry; hyaline cells in mid region quite short and broad, 3.3–2.5:1, in basal 1/2 of leaf on convex surface often with 1 large pore apically and/or up to 6 free pores, in apical region often with pseudopores along the cell margins; on concave surface with large round wall-thinnings in the cell ends and angles (these sometimes faint or absent); chlorophyllose cells triangular in transverse section and typically well-enclosed on concave surface. |
Sexual condition | dioicous. |
|
Capsule | with numerous pseudostomata. |
|
Spores | 24–33 µm, surface finely papillose to smooth, distal surface with distinct bifurcated Y-mark sculpture; proximal laesura more than 0.6 spore radius. |
|
Branch | fascicles with 2 spreading and 2 pendent branches.; branch stems with hyaline cells non-ornamented; no or weak funnel-like projections on the interior end walls, often with 1 large pore per cell on superficial cell walls. |
fascicles with 2 spreading and 2–3 pendent branches. |
Sexuality | unknown. |

Discussion | Sphagnum palustre may occur elsewhere than listed above, but the taxonomy is unclear. In some open-grown situations, it may have a reddish tinge and seem similar to S. magellanicum, but this is a pinkish red color rather than the purplish red of the latter. See discussions under 5. S. henryense and 9. S. papillosum for distinction from those species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
