Walter Lämmler – As a former assistant to Prof. Dr Elias Landolt, I was responsible for the Landolt Duckweed Collection from 2003 to 2021. Previously, I gained in-depth experience in the field while collecting duckweed on worldwide trips with Prof. Dr Elias Landolt.

The Landolt Duckweed Collection is no longer with me in Zurich.

It was handed over to the Istituto Biologia e Biotecnologia Agraria – CNR

But this does not nullify my interest in duckweed taxonomy.

I am still available for enquiries, exchanges of views, and cooperation on the morphology, distribution, and plant determination of duckweed.

I am supported by a database on duckweed (distribution of species, research literature).
