There are number of Aponogeton species that are farmed for the Aquatic plant and aquarium trade though not all species are easy or as great for aquaria. Jim yours looks a lot like Aponogeton undulatus. As I understand it though many of the cultivated plants are suspected to be hybrids or at least there are hybrid plants mixed. There are several species popular from Madagascar in the trade but they occur also on continental Africa, along the southern portions of Asia, and across to Australia as well. I think there are species native to Thailand but I know there farms there growing these plants for the trade as well and not just their native species found this interesting piece on Australian species http://aquaticlife.angfaqld.org.au/Aponogeton.htm Alani Davis On Mon, Mar 25, 2013 at 1:39 PM, Jim McKenney <jamesamckenney@verizon.net>wrote: > Back in early February we had a brief thread which began with speculation > about the identity of plants sold as Crinum thaianum in aquarium stores. > Jim Waddick mentioned that bulbs of aquatic plants were being sold in clam > shell containers in aquarium stores.
