A new species, Lindsaea kohkongensis (Lindsaeaceae), is described from the near Chamnar village of valleys of Koh Kong Province of Cambodia. This species is characterized by continuous marginal frond sorus and trilete spores, classifying it taxonomically within the genus Lindsaea. This species is distinct from other species of Lindsaea, such as L. walkerae, L. ensifolia, and L. heterophylla, in terms of different habitats and morphological characteristics. Lindsaea kohkongensis occurs in subaquatic environment and has pinnate fronds with distinct petiolules and terminal pinnae, and free, 1–2-forked veinlets except within the indusium. Detailed illustrations, photographs, and a distribution map of L. kohkongensis, along with morphological comparisons with the closely related species, are provided.
