Sphagnum junghuhnianum

Sphagnum bergianum

junghuhn's sphagnum
Habit Plants moderate-sized, soft, loosely tufted, slender, capitulum flat-topped to rounded; pale, dirty green, yellowish to brownish; without metallic lustre when dry. Plants moderate-sized to robust, capitulum more or less flat-topped and large; dark brown overall with a golden center to the capitulum and a distinctive deep red tinge in the field which becomes a pinkish purple sheen upon drying.
Stem(s)

leaves triangular-lingulate, 1.2–1.6 mm, broadly apex acute to narrowly truncate and toothed, border narrow or indistinct at base (less than 0.25 the width);

hyaline cells rhomboid, mostly 0–1-septate;

convex surface with membrane pleats, concave surface with 1–3 rounded membrane gaps occupying most of cell.

leaves broadly triangular-lingulate, 1.15–1.25 × 0.8 mm, apex slightly to broadly obtuse, border moderately broadened at base;

hyaline cells mostly 1-septate with a few to many 2-septate in the mid region, shape rhomboid.
Branches

somewhat 5-ranked.

more or less 5-ranked.
Branch leaves

ovate-lanceolate, 1.3–2 mm, strongly concave, apex strongly involute;

margins entire to somewhat toothed near apex, hyaline cells on convex surface with numerous ringed elliptic pores (6–10) along commissures, concave surface mostly aporose except near margins;

Sexual condition dioicous or monoicous.

1.2–1.3 × 0.65–0.75 mm, broadly ovate, apex involute;

hyaline cells on convex surface with numerous round to elliptic pores along the commissures, these grading from small pores at the apex to large pores at the base;

concave surface aporose except for a few large pores in the lower side regions.
Sexual condition

dioicous.
Spores

21–23 µm; minutely papillose.

26–30 µm.
Branch

fascicles with 2 spreading and 1–2 pendent branches.

fascicles with 2 spreading and 1 hanging branch.

Discussion

Sphagnum junghuhnianum in the flora area is known only from the Queen Charlotte Islands.

Sporophytes of Sphagnum junghuhnianum were not seen. Three other large, brown species of sect. Acutifolia have stem leaves without fimbriate to lacerate apices, S. subnitens (forms without red color), S. subfulvum, and S. flavicomans. Sphagnum flavicomans has a more pointed stem leaf and a darker brown color as well as a strongly different ecology and range. Both S. subnitens and S. subfulvum have a glossy sheen when dry that is lacking in S. junghuhnianum. Sexual condition and spore characters were taken from H. A. Crum (1984).

Sphagnum bergianum forms dense hummocks in medium to rich fen habitats and is associated with such species as Sphagnum warnstorfii, S. subfulvum, S. subsecundum, S. platyphyllum and S. fuscum.

Sphagnum bergianum is quite distinct in the field from its very dark brown color tinged with a deep red as well as its 5-ranked branch leaves. Sphagnum subnitens is colored a light brown and red combination, and has unranked branch leaves. Sphagnum subfulvum has a golden brown color that can be tinged with purple but also has unranked branch leaves. Sphagnum flavicomans is a similar-sized brown species of sect. Acutifolia that overlaps S. bergianum in Newfoundland but it is golden brown, lacks the red tinge and has a longer and narrower branch and stem leaves.
