| Abstract: |
| In August 2015, diatom diversity of the Yading Nature Reserve of Sichuan was investigated. Diatom samples were observed using light microscope and scanning electron microscope. Totally, 81 species (including varieties) were identified, belonging to 3 classes and 19 families and 31 genera, of which 2 species were newly recorded from China:Cocconeis placentula var. klinorahis Geitler and Psammothidium daonense (Lange-Bertalot) Lange-Bertalot. For two newly reported species, morphological characters, habits and the distributions were described in detail. |
