The HAC herbarium gathers the highest Cuban collections of dry plants before 1959, which belonged to 13 collections with their own characteristics and catalog numeration. All these collections are now integrated in HAC and HAJB, but there is not a unique catalog number for each specimen. The HFC series started after 1966, and this is the series for the Project of rewriting the Cuban Flora, initiated by the National Botanical Garden in collaboration with other institutions. The main collection is at the HAJB, but there are duplicates in HAC too. The main collections at HAC are: CSC: Colegio del Sagrado Corazón de Guantánamo (collector: Bro. Hioram) HABA: Academia de Ciencias Médicas, Físicas y Naturales de La Habana (collection of Ch. Wright from Sauvalle´s Herbarium) HFC: Herbario de la Flora de Cuba IH: Instituto de Segunda Enseñanza de La Habana (collectors: García Cañizares, Sebastián Alfredo de Morales, José Ignacio Torralbas, I.
