The river palm has adapted to live in rivers. Besides living permanently in the water, it's pretty much the same as its ancestor. To defend itself from stickyballs, which can be attached to a river palm by wingworms, it pumps water into the little pools developed from the segments. When such a pool is full, it will overflow, washing all of the stickyballs off. Even the leaves can be dropped, if they are infected with stickyballs. Because the river palm can reproduce by budding, the dropped leaves can grow a whole new plant somewhere else as soon as the stickyballs are washed off. The river palm can also throw off the two extra trunks at the base to reproduce asexually. The tip of the trunks is filled with air, so that they can cover a bigger distance until they root on their new home.

None found. Note that this does not necessarily mean it has no living relatives at all, but that, assuming all taxonomy is filled in, its entire phylum is extinct; any relatives it does have likely do not resemble it.
