Habit | Plants typically small and slender, larger and compact in the Arctic, capitulum small to moderate-sized, often with a conspicuous terminal bud; green, yellowish brown to brown; without metallic lustre when dry. | Plants moderate-sized, upright but weak-stemmed; golden brown to dark brown; capitulum distinct and often with strongly curved branches. | ||||
Stem(s) | leaves spatulate to broad-spatulate, 0.8–1.5(–2) mm, strongly lacerate across the broad apex and often part way down the margins, border scarcely to strongly broadened at base (0.25 width of base or less); hyaline cells rhomboid, efibrillose and often 1–2-septate. |
leaves triangular-lingulate to lingulate; 0.8–1.2 mm; apex rounded and sometimes erose; hyaline cells non-septate or sometimes septate, usually fibrillose in distal 1/2 of leaf, convex surface with very small pores (ca. 2 µm) along commisures and free, concave surface with fewer commissural pores. |
||||
Branches | not 5-ranked, quite terete, long, and slender Branch fascicles with 1– 2 spreading and 1–2 pendent branches. |
turgid and often strongly curved. |
||||
Branch leaves | ovate to ovate-lanceolate; 1.1–1.5(–2) mm, slightly concave, straight; apex involute; margins entire; hyaline cells on convex surface with numerous pores along the commissures grading from small pores near leaf apex to large pores at base, concave surface with large round pores at leaf apex and along margins. |
ovate-lanceolate; 1.4 or more mm; mostly subsecund; hyaline cells on convex surface with numerous small (2 µm or more) pores along the commissures and sometimes free, concave surface with no pores or fewer small pores along the commissures. |
||||
Sexual condition | often monoicous. |
