A common floating aquatic plant in An Giang, Vietnam is Centrostachys aquatica. The purpose of the study, " Identify centrostachys aquatica by using DNA barcoding“is to serve as a foundation for future research to identify specific medicinal properties for the treatment of human ailments.  The outcomes demonstrated that the leaves are cool-nosed, green, 1-1.5 cm wide, and 6-7 cm long. The veins are feather-shaped, and the lower surface is hairy while the upper surface is smooth. The inflorescence is 7–10 cm long and is made up of symmetrically growing clusters of several odd-sized flowers that range in size from 0.5–0.8 cm. a floating aquatic herbaceous plant with striped and occasionally red dots that is between 1 and 1.5 cm in size. The roots are short and twisted, and they get smaller from the neck to the tip over time. They have a diameter of 0.2 to 0.5 cm and are 10–15 cm long. There is a 98.35% similarity between the sequence of this RBCL gene and the sequence of Centrostachys aquatica that has been reported. As a result, the study uses DNA, a highly reliable and selective technology, to identify the species names of Centrostachys aquatica (R.Br.) Wall.
