Which plant is an aquatic plant species, Andira or Watercress?
Watercress Watercress is an aquatic plant species with the botanical name Nasturtium officinale. This should not be confused with the profoundly different and unrelated group of plants with the common name of nasturtium, within the genus "Tropaeolum".
Utricularia olivacea Utricularia olivacea, the piedmont bladderwort, is a very small, annual suspended aquatic carnivorous plant that belongs to the genus "Utricularia". "Utricularia olivacea" is native to Central America, South America, the West Indies, and the eastern United States (coastal plain from Mississippi to New Jersey).
