We present a conspectus of cormophytes species in the area surrounding the artificial lake of Surduc (Timiș County, SW Romania) whose dam was buil-up in the ’1975. Under the Romanian name Lacul Surduc, the lake water surface and a small belt of its border constitutes since 1995 a mixt nature reserve (WDPA ID 183478, category IV IUCN) of a 3.62 km2 total area. After 1990, the lake area became a local touristical attraction, and a chaotic implantation of summer residencies began. The list of species is compiled mainly from our field studies carried-on since 2000. This list contains: aquatic and paludicolous species (Caltha palustris, Carex riparia, Eleocharis palustris, Iris pseudacorus, Juncus spp., Lythrum salicaria, Mentha aquatica, Najas minor, Polygonum amphibium, Potamogeton crispus, Rorippa amphibia, Schoenoplectus lacustris, Typha angustifolia, Veronica anagalis-aquatica etc.), species from the surrounding deciduous forest (Fagus sylvatica, Quercus petraea, Carpinus betulus, Prunus avium, Crataegus monogyna, Rosa canina, Alium ursinum, Anemone nemorosa, A. ranunculoides, Erytronium dens-canis, Ficaria verna, Galium odoratum, Mycelis muralis etc.), meadows species (Agrostis capillaris, A. stolonifera, Alopecurus pratensis, Festuca rupicola, F. valesiaca, Leontodon autumnalis, Lotus corniculatus, Trifolium pretense, Plantago media etc.), weeds (Anagallis arvensis, Chenopodium album, Digitaria sanguinalis, Lathyrus tuberosus, Setaria pumila, Veronica persica etc.), invasives (Ambrosia artemisiifolia, Erigeron annuus, Rudbeckia laciniata, Phytolaca americana) and many ornamental trees and herbaceous planted in small gardens of residencies. Remarkable is the presence of Lindernia procumbens on S-E lake border, species listed in the Annex IV of the Council Directive 92/43/EEC. We noted that the anthropic pressure on aquatic and paludicolous vegetation increase since the beginning of our observations period, although some conservation actions were implemented.
