Inquiry: Blue Comandra umbellata rhizome tissue Good morning, in recent field work I happened upon some C. umbellata, which was a new one for me. I noticed that the vascular tissue in the roots has a bright, oxidized copper-like blue tissue surrounding it. I'm unable to find what this would be in the literature, and would guess it's sequestration or some kind of fungal association. Does anybody know or have a theory as to what this would be? Cheers.
