EXSICCATA AND TYPES IN THE A. BERGER’S HERBARIUM AT LA MORTOLA (HMGBH)

Alwin Berger (1871-1931) during his scientific activity at the Hanbury Botanical Gardens (1897-1915) and as succulent specialist have preserved more than 1,500 exsiccata and published more than 700 new taxa and combinations. The Berger’s succulent dry collection, preserved at the Herbarium Mortolensis [HMGBH] and characterized by approximately 1,400 exsiccata with 48 specimens potentially useful for typifications, and 59 genera is here presented and compared for the first time with the other collections deposited at the Smithsonian Institution of Washington [US], New York Botanical Garden [NY], and Royal Botanical Gardens, Kew [K]. Two projects focusing on the Berger’s succulent herbaria conservation, study and revision now being carried out so to contribute to the promotion of the monumental history of the Hanbury Gardens and the Berger’s systematic work on succulent families are presented.
