Cone: paired or 1, terminal, generally 4-sided, fertile leaves not like sterile, generally strongly keeled. Sporangia: 1 per leaf axil, 2 kinds, male (generally more distal in cones, spores many, small), female (spores (1)4, large, generally orange-yellow).

Common Name: SPIKE-MOSS

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 eremophila Maxon
Habit: Plant a mat, loosely spreading at margins where branching sub-pinnate; green aging orange-brown. Leaf: of main stem 0.4--0.6 mm wide, tip pointed up, acute; under-leaf of main stem 1.5--3 mm, +- lanceolate or sickle-shaped, decurrent, over-leaf 1.3--1.5 mm, lanceolate, not decurrent, base hairy or not; awn 0--0.03 mm. Cone: sparse, 3--10 mm.
Ecology: Shaded sites, sandy or gravelly soils, at base of rocks, in cracks; Elevation: < 1100 m. Bioregional Distribution: e PR, DSon; Distribution Outside California: to Arizona, northern Mexico.
