Hydrocotyle bonariensis, the largeleaf pennywort,[1] once a member of the family Apiaceae, now in the family Araliaceae[4] and of the genus Hydrocotyle, is a hairless and creeping[5] perennial.[6]
This plant has numerous white[5] to creamy-yellow[6] flowers, and the flower stalks can be 30 centimetres (12in) in height.[5]
Fruits and reproduction
The stems creep and root at the nodes; the plant spreads by rhizomes. Dollar Weed produces a dry dehiscent fruit that, at maturity, splits into two or more parts each with a single seed.[6]
Habitat
This plant lives in sandy areas of somewhat extreme conditions: very dry lands that are flooded sometimes.
This species colonizes sandy ground[5] and disturbed foreshore sites, estuaries, coastline, sand dunes and ponds.[6]H. bonariensis has also displayed a tendency to prefer, and be stronger at, higher elevations.[9]
Southern South America: Argentina, Chile, Paraguay, Uruguay
Neighbors
Colombian communities: In a remote sensing project for rapid ecological evaluation, H. bonariensis was found in Colombia inhabiting several of the evaluated areas; the last two communities are considered exceptional for the diversity.[11]
