Tripad
Descended from Bulbus aciecrescus 30 cm (diameter of pad), roots typically reach 3 - 5 meters down into the bed of the river B. flumuancoris is an aquatic plant descended from B. aciecrescus. They now float on the surface of the river, and use modified roots to anchor themselves to the riverbed. They grow from a single anchor, but once older, drop down tendrils with weighted tips to create backup anchors in order to prevent being washed away in case one breaks. They also tend to have several trailing tendrils that are dense enough to sink to the riverbed and drop down to become anchors when needed. These tendrils grow and drop weighted, oblong seeds, specially developed to drop down into and stick in the mud of Zone 14. Seedlings begin as a single stem and small pad, grown from the nutrients of the seed. They perform weak photosynthesis in order to make it to the surface and reach maturity. Once they do, they are able to perform much stronger photosynthesis, grow a larger pad, and drop down several tendrils to anchor themselves more firmly.
