SynonymsAmbuliaAmbulia sessiliflora; Hottonia sessiliflora; Stemodia sessiliflora; Terebinthina sessiliflora; Stemodiacra sessilifloraDistributionS.E. Asia Escaped into a number of countries where conditions are suitable and sometimes classified as a weed - in paddy rice fields of India, China, Japan and the Philippines. Now is naturalized in several counties in Florida, from south Florida to the Florida Panhandle. Some species are native to Australia.[1] EcologyVery adaptable; has been found growing in mountain streams, lakes, rivers and even damp soils. DescriptionLooks superficially rather similar to Cabomba but it has leaves in proper whorls, about 1.2 inches (3 cm) in diameter. The leaves are pinnate and bright green in colour. Under strong light the leaves take on a reddish hue. When the plant has received enough light for the day, the whorls of leaves tend to close up and "go to sleep".[2] Can reach over 16 inches (40 cm) in height. The submerse leaves are very different from the emerse forms - dark green, more or less lance-shaped. The fruit are capsules, ellipsoid, 3.5-5.5 mm long, green-brown when submersed, dark brown when emersed. CultivationQuite commonly used as a bunch plant in aquariums. Needs medium light (more light results in better growth and appearance) and a nutrient-rich water column. Benefits from the addition of CO2. Like many stem plants, it tends to take on a leggy growth in poor light. Propagated by cuttings. Growth conditions: Ph 6-7.5 3-25 dGH 3-25 dKH Temperature 22 - 28'C A nutrient-rich substrate also benefits the plant.
