I was having a walk outside in the nature and I saw the beautiful seeds of this herb.

I wasn't able to decide if they are shield-shaped or heart-shaped.

No matter the shape, they are very beautiful, so I took some pictures of them with my smartphone.

This photo is my entry to @travelcontest "Closer".

Once I got home I researched the species and found out this is Rumex.

https://en.wikipedia.org/wiki/Rumex

Its leaves are not only edible but also have many other uses...

Here is what wikipedia says about the use:

These plants have many uses. Broad-leaved dock (Rumex obtusifolius) used to be called butter dock because its large leaves were used to wrap and conserve butter.

Rumex hymenosepalus has been cultivated in the Southwestern US as a source of tannin (roots contain up to 25%), for use in leather tanning, while leaves and stems are used for a mordant-free mustard-colored dye.

These plants are edible. The leaves of most species contain oxalic acid and tannin, and many have astringent and slightly purgative qualities. Some species with particularly high levels of oxalic acid are called sorrels (including sheep's sorrel Rumex acetosella, common sorrel Rumex acetosa, and French sorrel Rumex scutatus), and some of these are grown as leaf vegetables or garden herbs for their acidic taste.[5][6]

In the United Kingdom, Rumex obtusifolius is often found growing near stinging nettles, owing to both species favouring a similar environment, and there is a widely held belief that the underside of the dock leaf, squeezed to extract a little juice, can be rubbed on the skin to counteract the itching caused by brushing against a nettle plant.[7] This home remedy is not supported by any science, although it is possible that the act of rubbing may act as a distracting counterstimulation, or that belief in the dock's effect may provide a placebo effect.[8]

In traditional Austrian medicine, R. alpinus leaves and roots have been used internally for treatment of viral infections.[9]

Rumex nepalensis is also has a variety of medicinal uses in the Greater Himalayas, including Sikkim in Northeastern India.[10]
