--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>terrestrial, forming diffuse mats. <b>Stems</b> long-creeping, usually ascending, sparsely branched, branches mostly simple or 1-forked, flat, not articulate, glabrous. <b>Rhizophores</b> axillary, 0.1–0.2 mm diam. <b>Leaves</b> delicate, papery. <b>Lateral</b> leaves well spaced, green, ovate to ovate-lanceolate, 1.6–2.65 × 0.98–1.64 mm; base slightly cordate; margins transparent, serrate; apex acute to slightly obtuse, conspicuously ending in teeth. <b>Median</b> leaves spaced, ovate-lanceolate to narrowly ovate-lanceolate (on basal stems), 1.3–2 × 0.4–0.8 mm; base oblique on inner side, rounded and prominent on outer side; margins transparent, serrate; apex long-acuminate to bristled. <b>Strobili</b> solitary or paired, lax, flattened, 0.4–0.7(–1.5) cm; sporophylls very strongly keeled, keel dentate, base slightly cordate to rounded, margins transparent, sparsely serrate, apex acuminate; megasporophylls larger and wider than microsporophylls, usually on underside of strobili.</span><!--

|discussion=<p>Among the species in the flora, <i>Selaginella ludoviciana</i> is most closely related to <i>S. apoda</i> (see discussion) and has often been included in <i>S. apoda</i>. W. R. Buck and T. W. Lucansky (1976) concluded that two species should be recognized based on anatomic and morphologic data. A close examination of distribution of sporangia in the strobili in many specimens reveals that sporangial arrangement may be more variable than reported by H. T. Horner Jr. and H. J. Arnott (1963). All species in the <i>S. apoda</i> complex (see <i>S. apoda</i> and <i>S. eclipes</i> for discussion on the complex) have sporophylls with fused blade tissue.</p>
