Phenotypic plasticity of the iridescent fernthing

Here are some specimens grown under relatively high lighting. The iridescence is of course nearly gone, but also note that the "leaf" edges are both smoother and more evenly gemmiferous.

I also noticed an uninvited angiosperm sprout just germinated in the cup the ferns pictured above were in. Its curly leaves stop being curly when it's unwilted.

Imperfect photo time: more phenotypic plasticity! The first one below was so close to being perfect but the color's slightly off and there's a bit of subtle fisheye distortion.
