Here is core information on all of our catalogued specimens of species in the family Lemnaceae. The table is now sortable (as of 19 SEP, 2012); click on a table heading to sort up; click again to reverse the sort direction. As yet it sorts dates as text strings, not actual dates (we’re working on this!).

Be aware that this information has not been fully proofed; also, more than half of our collections have not yet been databased, so this may not be complete either. Please do not hesitate to contact us for more specific queries, or if you see an error.
