An herbarium is a collection of preserved plant specimens that are pressed, dried, and mounted on paper. The specimens are labeled with scientific names, collector information, and location details. Herbaria serve as libraries of plants for identification purposes and research. They allow scientists to validate observations, study plant DNA, and track changes over time. Major herbaria around the world include Kew Gardens in London, the Natural History Museum in Paris, and the New York Botanical Garden. Herbaria are useful for identifying plants, understanding distributions, studying impacts of climate change, and aiding botanical education and research.
