Notes: This species is represented by the herbarium specimens only by several collection but rather common in central plane and the other parts of Thailand. The water plants can be carried by men among the roots of the other plants and grow actively when they find the suitable habitat. This species seems to become common throughout Thailand only recently, by getting appropriate habitats by the improvement of the irrigation system for paddy fields, and also by making new creeks along highways.
