I have a rocky world where land-based vegetation like grass or trees are either very rare and restricted to small and rare areas or non-existent. Rather, vegetation has stayed in the oceans and developed there.

So the question is that in the title, what natural cause could there be for the landmasses of a planet having few or no plants while the seas have plenty?

Edit: Note that animals still spread onto land, maybe feeding off photosynthetic animals rather than plants, or by feeding in lakes with plants

What would cause plant life not to spread onto land?
