Sphagnum sect. Polyclada
wulf's sphagnum
leaves smaller than branch leaves, triangular-lingulate, with rounded apex, border entire;
hyaline cells efibrillose, non-ornamented, rhomboid, septate; resorbed on convex surface;
concave surface intact except near apex.
dimorphic, spreading branches stiff;
pendent branches slender and delicate.
with chlorophyllous cells often with faint papillae on interior walls.
ovate-lanceolate, apex involute, border entire;
hyaline cells fibrillose and non-ornamented, convex surface with 4–6 small ringed ovate pores (approximately 1/4 the diameter of the cell), concave surface with 0–4 unringed pores per cell; chlorophyllous cells elliptic to truncate-elliptic in transverse section, qually exposed on both surfaces.
monoicous or dioicous.
with few pseudostomata.
15–24 µm; finely papillose on both surfaces;
proximal laesura less than 0.5 the length of the spore.
fascicles with 3(–8) spreading and 3(–8) pendent branches.;
branch stems with distinct solitary retort cells, necks not or slightly rostrate.
Sphagnum wulfianum
Sphagnum sect. Polyclada
The sporophytes of Sphagnum wulfianum are moderately common. This is the most dry-growing species in North America, typically growing in association with Sphagnum centrale, S. girgensohnii, S. russowii, and S. squarrosum. It is easily recognized as the only species that regularly has more than six branches per fascicle. The Lycopodium clavatum-like growth habit and conifer swamp habitat along with the strongly 5-ranked branch leaves make it even easier to recognize in the field.
