Attempt of comparative analysis of the segetal flora of Siedlce City with similar flora of areas of arable lands of the Siedlce Upland is presented in the paper. Received results show the larger value for urban flora of apophitysm coefficient - 63,3% (61% for Upland), flora modernization - 0,52 (0,42 for Upland) and flora lability - 19 (15 for Upland). On the other hand segetal flora of the Siedlce Upland is characterised by larger synanthropization coefficient - 104 (93 for the city). As to other differences, considerable larger participation of perennial species in the flora of the city (45,5% Siedlce; 37,1% Upland) is noteworthy. Moreover the occurrence of juvenile forms of arborescent species and plants running wild from gardens and parks, e.g.: Mathiola incana, Aesculus hippocastanus, Sedum reflexum, Nigella damascena, Helianthus tuberosus among species weeding urban cultivation is clearly noticeable
