The Herbarium is located at Pablo de Olavide University of Seville (Spain), a young public institution, founded in 1997, located on a single campus on the outskirts of the city. The herbarium was founded in 2002 by the current Professor of Botany at Pablo de Olavide Dr. Modesto Luceño Garcés. This is a small pubic herbarium specialized in two angiosperm families, Cyperaceae (sedges; especially from the mega-diverse genus Carex) and Resedaceae, coming worldwide but mainly from Europe, Iberian Peninsula and Mediterranean basin, according to the main research lines conducted in the Botany Area of the University. However, it has also a representation of a broad spectrum of angiosperms of these and many other parts of the world. Its funds currently consists of about 10,000 specimens in sheets. Its collection is being steadily increased and computerized. The sheets are previously frozen previously to its storage in an isolated room with controlled temperature and humidity and subjected to periodic pest control. In this room there is no staff working continuously in situ, which facilitates conservation and prevents possible contaminations and pest attacks. Once selected, materials of interest are studied outside the herbarium, in the laboratory or as material requested in loan. The herbarium staff currently consists of the Curator and a technician working part time.
