Really? Seaweed in the Forestry school? Yes, the EMMA herbarium houses a little and interesting collection of algae. All of them were collected on 1905. In other words, they predate the destruction of the EMMA herbarium in 1936. They may have arrived later as a donation or exchange, or they may have survived the catastrophe…

These are the usual labels for the EMMA Herbarium. The information accompanying each sheet (location, date, name of the plant, collector, etc.) is printed in one of them to be stored with the plant material.
