Abstract
In the frame of a wider research project, an inventory of 147
alien vascular plant taxa of the urban and suburban area of the city
of Thessaloniki, N Greece is presented. The floristic checklist is
based on extensive recent field work in 26 selected collection sites
of four development sectors of the metropolitan area of the city.
Each taxon recorded is given with information concerning its
life-form and chorology (critically compiled as origin and current
total distribution, given separately when possible), previously
reported occurrence in the area, biotopes (semi-natural,
anthropogenic), distribution in the investigated area and
quantitative estimation of its presence per collection site. The
most abundantly found taxon is Solanum elaeagnifolium,
followed by Ailanthus altissima, Cynodon dactylon, Crepis
sancta, Diplotaxis tenuifolia, Amaranthus retroflexus and Sporobolus
indicus. The annotated checklist includes earlier reports for 62
taxa and furnishes at least 85 new records for the flora of
Thessaloniki. Among them are 37 taxa not given for Greece in Flora
Europaea and 16 taxa not given for Greece in the Med-Checklist.
