I have signed up for pro bono work as a validator of aquatic plants for the National History Museum of Botany at the University of Oslo. Got my security clearance and access key card today, so spent the entire day immersed -- literally -- in the herbarium. A quiet and if I'm allowed to say so, rather dusty, place. However, somebody has to do the job and I volunteered. No idea for how long the task will take, but I expect to be busy for some months at least. I have to go through around 10,000 collections. mainly Pondweeds (Potamogeton, Stuckenia, and Groenlandia).
A quick view of my working space there. Now it's between me, the monographs, the Leica binocular microscope (which is excellent), and the herbarium sheets.
