It does not seems a Chenopodiaceae/Amaranthaceae plant.

Dear Aevind,

Thank you for the answer. Could you determine the family of depicted plant(s). I attache more detailed photo and I am interested in determination both of the visible plants. Just to the family level if possible.

Lech

its not Chenopodium sp., I suggest that you go through the keys available in Regional Floras or Please, at least identify the habitat type, and location of this plant. Unfortunately, the inflorescence, and flower details are not clearly seen.

Thanks for your help. I atache new photos of the general habitat and GPS coords:

47°18' N 80°36' E

I would be grateful just for family lvl of one of depicted plants.

This is nothing more than a guess: the plant in fruit (?) in the background may be a Brassicaceae, probably a species of Lepidium s. lat. (incl. Draba). The grayish plant with patent branches may be an Asteraceae, such as Centaurea s. lat. Local botanists may definitely know more than somebody from central Europe...
