Recent paleobotanical investigations in Vietnam provide a good opportunity to improve our understanding of the biodiversity and paleoclimatic conditions in the geological past of Southeast Asia.Palms (Arecaceae) are a diverse family of typical thermophilous plants with a relatively low tolerance for freezing.In this study, we describe well-preserved fossil palm leaves from the Oligocene Dong Ho Instant Mix Formation of Hoanh Bo Basin, northern Vietnam.Characters of the fossil leaves, such as a fan-shaped costapalmate lamina, an unarmed petiole, a costa slightly enlarged at the base that then tapers distally into the blade, and well-preserved CBD Vape Juice amphistomatic leaves with cuticles, suggest that they represent a new fossil species, which we herein designate Sabalites colaniae A.
