With all those trees I submitted, the forest floors (currently excluding taigas but I'll get to them) on the different landmasses now have distinct light levels which can influence the future evolution of organisms. From darkest to lightest:

Dixon-Darwin and Vivus: Nearly pitch black; shadows cast by Obsidoak, which is a shade tree, contain very little reflected light due to it being black flora, and the same goes for the Gargantuan Obsiditree especially in the rainforests. Smaller forest flora on the supercontinent should be adapting to extremely low light levels.

Drake and Ramul: Dim, but not lightless. Crystals are reflective, so a fair bit of green light should be reaching the forest floor. There should be a fair amount of flora on ground level.

Maineiac: Fairly bright, enough to potentially support a diverse collection of smaller bushes and shrubs, as the large flora there do not cast huge shadows. The forest floor should be fairly lush, though gaps should also exist.

Hydro and Barlowe: Brightest, most sunlight reaches the forest floor, due to the native flora being unbranching/palm-like and not being able to form anything resembling unbroken canopy. The forest floor should be extremely lush.

Fermi excluded because it has no forests.

Is this helpful as a reference? I can try to update it as the continents shift and more flora evolve.

Something this handy should be on the wiki, too, and perhaps on the habitat listings.

All these different colors/types of trees are going to cause interesting continent-specific phenomena or regional flora looks...
