An herbarium is a collection of preserved plant specimens that are used for scientific study and reference. These specimens are typically dried, pressed, and mounted on sheets of paper, along with labels that provide information about the plant's name, location, and date of collection. Herbaria play a crucial role in botany, ecology, and conservation by helping researchers identify and classify plants. Herbaria are often maintained by universities, research institutions, and museums. They serve as valuable resources for studying plant diversity, distribution, and evolution. Additionally, they can aid in the identification of medicinal plants and contribute to the understanding of ecosystems and environmental changes.
