Edit KG: when Don left the forum, he removed the contents of all his posts. Since there is now nothing here, I will add a beautiful picture of f2r.

   

This seems like one of the only roots that very clearly look like a manufactured object. I'd personally stick with your first impression. Wouldn't it make a nice table as well?

Unfortunately, Don removed his posts. I do not remember with what he compared this root, but I see Hydra here ([font='Linux Libertine', Georgia, Times, serif]Gorgon). [/font]

The second question is the object next to the stem. It's not a blot. Does the object look like a seed?

My first thought was that the object next to the stem was a parchment hole, but after checking I realise it's not.
It looks a bit like a seed on a stem leading out from the main trunk, although no idea what this is supposed to represent. With the green smudge around it, maybe it is the formation of a new root underground?

I was thinking of "Knöllchenbakterien", the kind of bacteria which help some plants to assimilate nitrogen. Sorry, but I am not clear about the English terminology

More shapely roots in this MS as well.
