General Description
Plants: Forming lawns in areas protected from the sun and high, thick hillocks in open areas; stem leaves of shaded plants a little distant, in open forms crowded and stiff; color varying from green or green tinged with pink to red with purple tones (FNA 2007).”

Stems and Stem Leaves: Stems green to reddish. Stem leaves seldom similar to the branch leaves, somewhat tongue-shaped with an obtuse, rounded apex, the edge fringed, the outer surface frequently reassimilated and eroded away, to 2 mm in length, and to 0.7 mm in width (FNA 2007).

Branches and Branch Leaves: Branch stems green, the branches short to long and narrowing, dimorphic, the fascicles consisting of 2-3 pendent and 2-3 spreading branches. Branch leaves overlapping lightly, widely ovate, to 2 mm in length, and 1 mm or more in width (FNA 2007).

Stem and Stem Leaf Cells: Stem hyaline cells swollen and thin-walled, in 3-4 layers, the spiraling fibrils that strengthen the outermost layer of cortical cells distinct, the inner cell walls lacking comb fibrils, each cell with 1 or 2 pores (FNA 2007).

Branch and Branch Leaf Cells: Branch stem cortical cells frequently possessing large round pores on the outermost walls, lacking ornamentation; retort cells not present. Branch leaf hyaline cells lacking ornamentation, the cell faces on the convex leaf surface showing oval to round pores at the margins contiguous to the green cells; green (chlorophyllous) cells in X-section lens-shaped, not exposed on either the upper or lower surface (FNA 2007).

Phenology
Capsules ripen in midsummer (FNA 2007).

Diagnostic Characteristics
S. magellanicum is the only reddish-purple boreal species. The green cells of the branch leaves in X-section are totally enclosed in S. magellanicum. In the similar S. centrale, the green cells have thickened ends, thus exposing them slightly, particularly on the concave surface of the leaf (FNA 2007).

Habitat
From low- to high-nutrient fens and peatlands, exposed and wooded bogs (FNA 2007), frequently in the areas of higher acidity in the bogs (in older and drier edges and on tops of hillocks), seeping mountain inclines, pocosins (Crum and Anderson 1981). Elevations: low to high (FNA 2007).

Reproductive Characteristics
Dioicous. Capsules arrayed with many pseudostomata (FNA 2007).
