The Russell Johnson herbarium is housed in the library of the Cambridge Campus of Anoka-Ramsey Community College in Cambridge, Minnesota.
The herbarium is a collection of pressed and dried plant specimens including seedless vascular plants (mostly ferns: Pteridophyta), gymnosperms (mostly Coniferophyta) and angiosperms (flowering plants: Magnoliophyta). Specimens continue to be added to the collections.
The herbarium serves students as a plant reference collection from which they can learn botanical classification, plant relationships and experience examples of the magnitude of botanical diversity. Students can also learn plant preservation, storage techniques and shelving models.
