A several-year study of distribution, phytocoenological differentiation, floristic composition and structure of ruderal flora and vegetation and relevant anthropogenic influence was conducted at Pancevacki Rit in Serbia. Ten clearly distinctive ruderal communities were identified in the study, including the newly formed community Matricaria-Helianthetum annuae. This community is a unique combination of transitional ruderal and agrestal vegetation developing spontaneously in close vinicity of intensively cultivated agricultural fields, in which sunflower (Helianthus annuus L.), and annual crop, appears and persists subspontaneously and often massively, rendering a physiognomical character to ruderal habitats in which ephemeral ruderal weed vegetation often develops, consisting predominantly of annual plants of Sisymbrion officinalis.
