       Abstract: A new speciesꎬ Selaginella pseudotamariscina X. C. Zhang & C. W. Chen (Selaginellaceae)ꎬ is described
       from Vietnam. The placement of this species within Selaginella subg. Stachygynandrum is assessed based on molecular
       phylogenetic analyses and morphological comparisons with related species. Molecular phylogenetic analyses suggest that
       S. pseudotamariscina is sister to S. digitata ̄S. imbricata clade. Morphologicallyꎬ the new species is similar to S.
       tamariscina and S. pulvinata by sharing the rosette ̄forming habitꎬ but distinguished by its dorsal leaves symmetricalꎬ
