Museum Herbarium of Molise (MEM) was founded in 2000 thanks to the work and the contributions of teachers and students and has become a centre for the study of plant taxonomy and biodiversity conservation. The MEM houses collections of dried and mounted plants collected mainly from the Molise region, central-southern Apennines and Eastern Europe mainly. The Herbarium is listed in the Index Herbariorum, the global network of herbaria managed by the Botanical Garden of New York (NYBG), with the acronym IS. Nowadays the MEM collects around 11000 specimens and the collection is still growing with a yearly addition of new specimens. The plants are arranged in a systematic order: family, genus and species. The Herbarium is open to visitors and researchers by prior arrangement. The Herbarium carried out research on systematic, phenology and morphology of angiosperm families.
