Terniopsis chanthaburiensis (Podostemaceae), a new record for China and its complete plastid genome
Nordic Journal of Botany, EarlyView.The genus Terniopsis consists of plants that have not been thoroughly studied, with many species remaining taxonomically unresolved. In this study, Terniopsis chanthaburiensis is reported as a new record of China based on morphological traits. Then, we assembled and annotated its chloroplast genome based on genome skimming data.
