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.
Giulio Pontedera Giulio Pontedera (7 May 1688 – 3 September 1757) was an Italian botanist of Tuscan origin. He was professor of botany at Padua, and director of the botanical garden there. Although he rejected Carl Linnaeus' system, Linnaeus was a correspondent of Pontedera's, and named the genus "Pontederia" after him.
