It could be about the angle of incidence of the light striking it. The
pistil has a lot of direct light, whereas the stamens don't (except the one
on the bottom where you can see a bright edge). I had some similar problems
with developing a wax material. I find it best not to mix interior fading
with media. Rather adjust the densities and colours of the scattering
media and use absorption media to attenuate the light instead. You may
also want to try other scattering media types than the one you have.
