This is my first reply here in this forum. I've tried before but for some reason I can't read what I have posted. Thus, I'll write again.
In fact there are bioluminescent plants! While camping close to the Serra do Mar State Park (Parque Estadual da Serra do Mar) in the forests around the city of Embu-Guaçu, State of São Paulo, Brazil, I saw a species of plant whose leaves emitted discreet light, seen only at night. The light is produced by the leaves themselves and not by microorganisms like fungi or bacteria. I know the exact localization where these plants grow and was surprised by the fact that botanists don't know this plant species emit light. Indeed, the plant light is seen only in darkness. I think this plant has been collected and even identified but botanists don't know they emit light because the phenomenon is seen only at night and the plant must be alive. It is not possible to see the phenomenon during daylight and in dry, exsicatted plants.
Actually, I am not the first one who discovered the plants emit light. As far as I know, the first ones who discovered these intriguing beings emitting light are two brave women who camped at that place long time before me.
