Landoltia punctata illustration description |
| Résumé : |
"Landoltia punctata, native to Australia and SE Asia, was first recorded in The Netherlands in 2007. The species can be recognized by the narrowly egg-shaped to slightly kidney-shaped fronds, with one or three curved nerves. The ventral side if often purplish-red, especially at the margin. The fronds have more than one, but always relatively few roots. The species was often encountered as contamination in water tanks at garden centres and pet shops selling aquarium plants. It is very plausible that Landoltia punctata has been introduced as a contamination with aquarium plants from South-East Asia. In Europe the number of recent records is low and some were only temporary. It is not very likely that the species will be a nuisance to water management in The Netherlands. Its ecology hardly differs from other indigenous duckweed species and the risk of replacement of a native species is very low." (source : auteurs) |
