pollination in aquatic plants

So many aquatics seem to prefer to reproduce asexually. Is waterborne pollination that much chancier than airborne? Or, hm, my impression is that even aquatics with aerial flowers have an asexual tilt, so maybe it's not about the pollination?

I should find this paper Evolution of Aquatic Angiosperm Reproductive Systems:

Why do most aquatic plants reproduce asexually? [...] Why and how did hydrophily (water pollination) evolve, and why are only 5% of aquatic plants hydrophilous? The authors discuss hydrophily at length.

Also, do any plants use aquatic creatures as pollinators? Why the heck not? It would please me.

that reminds me: why are there so few insects in the ocean?

Yesterday I ate the single yellow currant tomato that the volunteer in the ginger pot managed to set. It was an excellent savory fruit in the not-exactly-tomato way those yellow currant tomatoes have. I should grow them again. Now, though, I'll snip down this spindly plant and let the ginger have the pot; I didn't think it was coming back up, but it has.

Today I ate the single green bean that has come to non-miniature size, though in this case there will be more. Yes, this does mean that I heated up the skillet to cook one bean. I did not dirty a plate for it, though -- I ate it with a fork. It was, unsurprisingly, excellent.
