Cone: paired or 1, terminal, generally 4-sided, fertile leaves not like sterile, generally strongly keeled.

Spring, resurrection plant. Hand lens, generally at +- 20×, required for leaves (shape, margin, awn at tip), cones. Selaginella kraussiana may be naturalized in California, differs from native California taxa in leaves lacking abaxial groove.
Unabridged Note: All native California taxa in subgenus Tetragonostachys.

Selaginella oregana D.C. Eaton
Habit: Plant in festoons, curly when dry, internodes > 1 cm; green or +- yellow aging to tan, then gray. Leaf: of main stems 1.4--2.4 mm, 0.4--0.06 mm wide, lanceolate, +- decurrent, base glabrous, margin +- toothed; awn 0.1--0.4 mm, +- rigid, entire. Cone: often paired, 10--60 mm.
