N2 - Lindernia dubia is a North American species colonizing mainly muddy big river banks. It was imported to Europe in the middle of the 19th century. The species has been spreading from France and Italy into Central and Eastern European countries, probably with waterfowl and men. In the Czech Republic L. dubia was firstly found in 1989 in southern Bohemia. Nowadays 8 localities are known for this species. At 4 localities it has been observed by authors; other 4 localities are known from literature. The most abundant population of neophytic L. dubia was found together with native species L. procumbens on exposed bottoms of storage ponds in the town of Hluboká nad Vltavou, southern Bohemia. We compared the ecological requirements of both species following data of phytosociological relevés. Both species are thermophilous herbs. In storage ponds (Hluboká nad Vltavou) the seedlings of both species appear generally at the same time at the end of May or beginning of June. Development of vegetation on exposed bottoms of storage ponds depends on time of ponds drying. In case of early drying period before germination time of Lindernia species, the storage ponds are overgrown by vegetation. Then, in the end of May L. procumbens is not able to penetrate into vegetation anymore. Beyond that L. dubia, thank to its more robust growth that L. procumbens, has a capability to penetrate on these taller plant stands. If storage ponds are dried in germinating period of Lindernia species, than both species successfully participates on the succession from the beginning and have the best conditions to colonize free space of exposed storage pond bottoms. It is likely that L. dubia is competitively stronger herb than L. procumbens. Therefore its spreading is expected. In this connection there is meantime unconfirmed assumption of invasiveness of L. dubia.
