Hydrocotyle bonariensis, the largeleaf pennywort, once a member of the family Apiaceae, now in the family Araliaceae and of the genus Hydrocotyle, is a hairless and creeping perennial.
Description Flowers This plant has numerous white to creamy-yellow flowers, and the flower stalks can be in height. 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. Habitat This plant lives in sandy areas of somewhat extreme conditions: very dry lands that are flooded sometimes. Community species Ipomoea pes-caprae Senecio crassiflorus Juncus acutus Co-dominate species Imperata brasiliensis Bacopa monnieri
Distribution This species colonizes sandy ground and disturbed foreshore sites, estuaries, coastline, sand dunes and ponds. H. bonariensis has also displayed a tendency to prefer, and be stronger at, higher elevations.
