_Lemna minor_ is a synonym of _Lemna disperma_ (or vice versa) commonly called
"Duckweed". There are a couple of other plants which are very similar (and
also called Duckweeds) - _Spirodela oligorrhiza_ and _Wolffia australiana_.

Depends on the type of snail - some can be very destructive to plants...
Check out the snail section of the Fish/Aquaria FAQ files - they describe
various types and their effects.
