Taxonomic Comments
FNA (1993, vol. 2) and the Pteridophyte Phylogeny Group I (2016) recognize the family Selaginellaceae with a single genus, Selaginella. Attempts to recognize subgenera (e.g., six in Zhou and Zhang 2015, seven in Weststrand and Korall 2016) lack consistency, and the elevation of subgenera to nineteen genera in Zhou and Zhang (2023) has mixed acceptance. While Weakley and the Southeastern Flora Team (2025) treat their fifteen taxa in four genera, Valdespino et al. (2024) provide justification to conserve Selaginellaceae in a single genus with approximately 750 taxa, which the World Flora Online (2025) accepts, following the Pteridophyte Phylogeny Group.
