Discusión taxonómica
Selaginella reflexa is related to S. schiedeana, which differs in having larger and more lanceolate lateral leaves (1.5–2 mm long) that remain flat and do not curve around the stem, short-ciliate median leaves with narrower white margins, and lateral leaves long-ciliate proximally.A
