Abstract

A five-day botanical survey for ferns and lycophytes was carried out between 15th and 19th May 2023 during the Heart of Borneo (HoB) Scientific Expedition in the Mount Sinsing area, Nuluhon Trusmadi Forest Reserve, Tambunan, Sabah. A random collection of ferns and lycophytes was made along the existing trails and surrounding area. In addition, some common species were also observed and recorded. As a result, 25 families were identified, comprising 67 genera with 140 species and infraspecific taxa. Among the findings, eleven species are endemic to Borneo, including one endemic to Sabah, which is Calymmodon pallidivirens (Polypodiaceae). Two of them are also listed in the rare and threatened pteridophytes of Asia, namely Calymmodon pallidivirens and Prosaptia borneensis. Asplenium borneense (Aspleniaceae), Cibotium arachnoideum (Cibotaceae), Davallia kinabaluensis (Davalliaceae), Dennstaedtia ampla (Dennstaedtiaceae), Elaphoglossum stenolepis (Dryopteridaceae), Diplopterygium bullatum (Gleicheniaceae), Lindsaea carvifolia (Lindsaeaceae) and Loxogramme carinata (Polypodiaceae) are restricted species, species that only known to a few localities, from two to three islands, including Borneo. This result represents 15% of the taxa reported in Sabah, and interestingly, Asplenium aethiopicum (Burm. fil.) Bech. subsp. aethiopicum is a new addition to Bornean region. This discovery significantly contributes to botanical knowledge and understanding of Sabah's ferns and lycophytes. This information will undoubtedly be helpful for further research, conservation initiatives, and understanding of the distinctive flora of the Malaysian Borneo.
