A herbarium is a collection of preserved plants or plant parts, usually in a dried form. Most of them are connected to academic institutions. This category lists websites for herbaria around the world.
Although the web has sprouted many virtual herbaria, i.e. online collections of plant images, this category lists only institutions holding physical collections. Image galleries are listed in other areas of the directory, for example Home: Gardening: Image Galleries or the most appropriate subcategory of Science: Biology: Flora and Fauna: Plantae.
