Tiny Seeds are Possible When You're a Plant That Parasitizes Fungi

Seeds of the Ghost Plant, Monotropa uniflora are TINY - barely .6 x .1 mm in dimension, resembling little beige hairs. They can afford to be so tiny bc - like orchids, they need only to land on their host fungus to be successful to germinate & get cell division going.

This plant, ot course, parasitizes mycorrhizal fungi & this does not produce any chlorophyll at all, nor does it undergo photosynthesis.

They won't actually be producing leaves that need contact with the sun and utilizing that as a source of energy. They will have an endless source of energy so long as they make chance contact with the mycorrhizal fungus that they steal their energy from.
