Built and u Alpinia aquatica (Koen.) Rose." from China were directly sequenced using an automated se-quencer. The result showed that both sequences were identical. The size is 178 bp in ITS 1, 232 bp in ITS 2 and 164 bp in 5.8S coding region, G + C content being 56.9 . According to the morphological and DNA characters, it was suggested that " Alpinia aquatica (Koen.) Rose." recorded in Flora of China should be Alpinia nigra (Gaertn.) Burtt.
