A member of the Polygonaceae to be identified

I imagine this is a Rumex but so far I haven't been able to identify the plant which I found growing at a quota of 3500 ft. Habitat was damp and heavily shadowed. Geographical area Southern Italy. Hopefully this plant is also to be found growing in the US., making it recognizable. Any help greatly appreciated.

 

Last three pics look like Rumex acetosa or R. thyrsiflorus or other close relative.

First two pics are something different; not sure what.

 

#2 - perhaps Picris.

 

Hi! The first two pics are the Base leaves and intermediate leaves of the same plant. This is what is puzzling. However, when one examines the leaves in pics 4-5, one can see the same resemblance to the lower stem leaves. The basel leaves are different, but not all, but then we see so many plants with differing basel and intermediate leaves. Thank you for your reply. I will investigate the sp. thyrsiflorus.

 

Probably, Rumex pulcher - with its hairy stem. Other Rumex species are normally glabrous.

 

Hi Andrey, I have checked to Italian Botanical sites for Picris and Pulcher, also Pulcher Ssp. pulcher. I cannot find photographs of the sp. Picris, but I found photographs of Pulcher and also the Subsp. The form of the leaves of Pulcher do not match my Rumex. You might like to visit these two sites "Acta Plantarum" and "Flora Italiana". Thank very much for you suggestions. towler
