A reply from David Merrick ji at Rumex (Polygonaceae) page with comparative images:
For R. dentatus I've attached the description I have (and the related R. pulcher) which is that it is an annual with 0 or few twiggy branches, the species having a "stiff" look. The last five R. dentatus photos on the page seem to depart from that description. The 1st pic of all those presented for R. dentatus does give a much more fitting presentation of those qualities to my mind. Beyond my reading I've no special experience of the species so others may know better. d

Thanks a lot, David ji.

I have gone through the images at our species page at Rumex dentatus L.

It appears in line with other observations at the page.

Fruits also match with others.

It is possible that there are many plants of the same species giving an impression that it is a single plant with spreading branches from the base.
