Stem: wiry, generally rooting adventitiously [or not], branching variable, generally not fragile when dry. Leaf: many, simple, overlapped, appressed, small, ± scale-like, 1-veined, generally grooved abaxially [or not] nearly to tip, generally ± of 2 kinds ("under-leaves" under main stem, "over-leaves" over it). 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).
1 genus, ± 700 species: worldwide, generally tropics, warm temperate. [Valdespino 1993 FNANM 2:38–63] —Scientific Editors: Alan R. Smith, Thomas J. Rosatti.
(Latin: small Selago, ancient name for some Lycopodium) Some cultivated as groundcover, curiosity: Selaginella kraussiana (Kunze) A. Braun; Selaginella lepidophylla (Hook. & Grev.) 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.Key to Selaginella
Unabridged note: All native California taxa in subgenus Tetragonostachys.
Plant mat-forming in sun, to elongate-creeping with sterile shoot internodes often > 7 mm in shade; green aging tan then gray. Leaf: of main stems 1.4–2.5 mm, 0.3–0.7 mm wide, lanceolate, generally not decurrent, color unlike brown of stem, base glabrous, tips of leaves of sterile stems thickened around end of abaxial groove; awn 0.2–0.5(0.9) mm, rigid, ± toothed. Cone: often paired, 10–45(90) mm.
Rocky outcrops, open to shady, dry to moist sites, chaparral to mixed-evergreen forest; < 1820 m. Northwestern California, Cascade Range Foothills, n Sierra Nevada Foothills (Butte Co.), n High Sierra Nevada, n San Francisco Bay Area (Marin Co.); to British Columbia, Montana. [Online Interchange]
