Definition
An herbarium is a collection of preserved plant specimens and associated data used for scientific study. These specimens are typically dried, pressed, and mounted on sheets of archival paper. The sheets are then stored in cabinets, organized by plant family, genus, and species. Herbaria serve as invaluable resources for botanical research, conservation, and education. Think of it like a library, but instead of books, it's filled with plant 'snapshots' taken over time.
