Lycopodium carolinianum L.
Stem branched, creeping on the ground, rooting along its length, up to 6 mm in diameter, sometimes producing irregular pale yellowish tubers. Leaves slightly dimorphic, lanceolate to oblong or linear-lanceolate in outline, apex tapering to a point, often ± falcate; lateral leaves up to 15 x 4 mm, spreading horizontally, membranous, slightly larger than the dorsal leaves, dorsal leaves somewhat appressed to stem or curving erect. Strobili solitary, cilindrical, 15-95 × 6 mm, borne at the apex of an erect peduncle; peduncle 4-35 cm long, sparsely set with appressed, reduced leaves. Sporophylls 3.5-6 x 1.5-2 mm, yellowish, broadly ovate, tapering with a deflexed point, erose-denticulate. Sporangia 1-1.3 mm wide.
Can be distinguished from L. sarcocaulon by having membranous lateral leaves that are of similar size or slightly larger than dorsal leaves and lance-shaped to oblong in outline.
caroliniana: the first specimen was collected in Carolina, United States.
