Detailed Checklist of the Grammitid Specimens from the Biological Museum Herbarium under VNU University of Science (HNU)

This study aims to compile a detailed checklist of grammitid specimens kept in the Biological Museum Herbarium under VNU University of Science (HNU). The study adopted the Pteridophyte Phylogeny Group classification (PPG I 2016) to classify these specimens and fifteen references were used to identify their scientific names. Detailed field labels in HNU provided various and rich data for compiling the checklist. The study analyzed 43 collection field numbers and identified 16 species of 7 genera. The richest in species was Oreogrammitis with 5 species; two genera (Prosaptia and Scleroglossum), each with 3 species; one genus (Calymnodon) with two species; and three other genera (Cteropterella, Themelium and Tomophyllum), each with one species.
