A plant specimen is a sample of a plant that is collected for scientific study and identification. These specimens can include leaves, flowers, seeds, or entire plants, and are often pressed and dried to preserve their structure. They are typically stored in herbaria, which are collections of preserved plant samples used for research and education. Plant specimens are essential for understanding biodiversity and the relationships between different species. They help scientists, such as botanists, identify new species, study plant evolution, and monitor environmental changes. By examining these specimens, researchers can gain insights into ecosystems and the effects of climate change on plant life.
