Abstract

A checklist of all species of ferns and fern allies that are known in Brunei is presented. The native, introduced, and endemic status in Borneo for all taxa are given. Ecological notes on distribution within Brunei as well as abundance or rarity are also provided. This checklist comprises 32 families, 106 genera and 364 species. We examined and re-identified all specimens of ferns and lycophytes in the National Herbarium of Brunei Darussalam (BRUN) at the Forestry Department and the University of Brunei Darussalam herbarium (UBDH) accordingly. The checklist suggests the threat status for each species, specifically, if it may be of least concern or rare in Brunei. Additionally, five new species belonging to the family Polypodiaceae are newly described here, viz., Acrosorus pectinatus Parris, Calymmodon ashtonii Parris, Calymmodon minutus Parris, Calymmodon rupicola Parris, and Ctenopterella rivularis Parris.
