The RBG (Royal Botanical Gardens) has 33 large file cabinets with about 80 000 plant files so one has to take some care in placing the False Mermaid in the correct place so it can be found again.
The files are colour coded. There is a colour for RBG property plants, for Hamilton/Burlington plants not on RBG property, for Ontario plants not in Hamilton/Burlington, for wild plants in other parts of the world, for garden plants planted at the RBG, and for garden plants planted in other gardens around the world.
Of the 80 000 specimens that are at the RBG Herbarium, some are more than 200 years old and some were put on the shelves yesterday. Some are special plants that were first found and identified at the herbarium. Some are duplicates that are destined to move to other herbariums. Most stay in their files for study by students and others concerned with plant identification, changes in plants, and changes in plant populations in various environments
It has been my privilege, since retiring as an elementary school teacher, to volunteer one half day a week for the last several years in this herbarium where I have learned much more than I ever knew about plants and been of some help to the herbarium and RBG in the process.
