At this moment (end 2001), there are four slight different plants known as Cryptocoryne usteriana. First the plant collected by Josef Bogner on Guimaras (Philippines) in1983 (Bogner 1644). This one is widespread in Europe. Second, a plant from Russia, shipped by Alexei Bednii, from an unknown origin. Third, a plant brought by Claus Christensen, originating from or near Cebu. Fourth, plants collected by Morco in Guimaras (Philippines) and frequently shipped to Europe.The plants are referred here as “Bogner, Bednii, Christensen and Morco” for ease. All plants are very easy to cultivate and are good aquarium plants.
