Seven species of Areca (Arecaceae) are here described as new: Areca bakeri, A. churchii, A. dransfieldii, A. gurita, A. mogeana, A. riparia and A. triginticollina. Five of the species are endemic to Borneo, one to Sumatra and one to Cambodia. A discussion of morphological characters, such as habit, leaf structure, inflorescence architecture and floral structure is presented for the species and putative relatives. Distribution, ecology, habitat, uses and conservation status are also discussed.
