Which is an aquatic plant, Pontederia or Heuchera?
Pontederia Pontederia is a genus of tristylous aquatic plants, members of which are commonly known as pickerel weeds. "Pontederia" is endemic to the Americas, distributed from Canada to Argentina, where it is found in shallow water or on mud. The genus was named by Linnaeus in honour of the Italian botanist Giulio Pontedera.
Cornops aquaticum Cornops aquaticum is a semiaquatic species of grasshopper native to the Neotropics, from southern Mexico south to central Argentina and Uruguay. It feeds and breeds exclusively on members of the aquatic plant family Pontederiaceae, especially water hyacinth ("Eichhornia crassipes"), and is being investigated as a possible biological pest control agent for the water hyacinth in countries where that plant is invasive.
