[edit] Common name
Dwarf Ambulia; Ambulis; Asian Marshweed
[edit] Synonyms
Ambulia Ambulia sessiliflora; Hottonia sessiliflora; Stemodia sessiliflora; Terebinthina sessiliflora; Stemodiacra sessiliflora
[edit] Distribution
S.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 panhandle.
[edit] Ecology
Very adaptable; has been found growing in mountain streams, lakes, rivers and even damp soils.
[edit] Description
Looks superficially rather similar to Cabomba but it has leaves in proper whorls, about 1.2 inches (3cm) in diameter. The leaves are pinnate and bright green in colour. Under strong light the leaves take on a reddish hue. Can reach over 16 inches (40cm) 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.
[edit] Cultivation
Quite 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. May be confused with other stem plants with similar appearance.
