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 moderate-sized to robust, somewhat lax in shade forms to quite compact and stiff in open grown forms; green to pinkish green to reddish purple; forms lawns in shaded habitats and low to moderately tall, dense hummocks in open habitats. |
Stem(s) | leaves to 1.7 × 1 mm, occasionally longer; rarely hemiisophyllous; hyaline cells non-ornamented, nonseptate. |
leaves to 2 × 0.7 mm; rarely hemiisophyllous; hyaline cells non-ornamented, mostly nonseptate. |
Branches | long and tapering, leaves ± imbricate to spreading in shade forms. |
long and tapering to short and pointed, leaves loosely imbricate. |
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. |
broadly ovate, to 2 × 1 mm or more wide, broadly ovate, hyaline cells non-ornamented, convex surface with round to elliptic pores along the commissures; chlorophyllous cells short-elliptic in transverse section and well-enclosed on both surfaces. |

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.) |
As the only boreal species of the section with a reddish purple color, Sphagnum magellanicum is usually easy to identify. The branch leaf chlorophyll cells are capable of being confused only with those of S. alaskense, which are less enclosed on both surfaces, and S. centrale, which has thickened end walls on the chlorophyll cells that give them a narrow exposure on the concave surface.
