Selaginella pseudorepanda (Selaginellaceae) – новый вид из южного Вьетнама

A morphological and molecular phylogenetic study of Selaginella specimens from Khanh Hoa, Dong Nai, and Dak Lak Provinces of Vietnam, previously identified as S. repanda, was conducted. As a result, it was concluded that these specimens represent a new species described here as S. pseudorepanda. Morphologically, this species resembles S. kurzii and S. repanda, but it is easily distinguished from them by having creeping main stems, a contiguous and imbricate arrangement of dorsal and ventral leaves on the main stems and branchlets, margins of ventral and axillary leaves densely long-ciliate, and ovate dorsal leaves with acuminate apex. The molecular phylogenetic analysis resolves S. pseudorepanda as a sister to S. minutifolia. Moreover, results of the spore morphology study also confirm that S. pseudorepanda is a distinct species.
