Abstract
The origin and identification of the 28 specimens of Cactaceae in the Willdenow herbarium in Berlin (B-W) are discussed. The eight Humboldt & Bonpland specimens from South America constitute the most important part of the collection, including five isotypes. Further, rather poorly documented specimens are of uncertain, presumably Caribbean or Central American origin or from a horticultural source. A detailed list arranged according to B-W numbers is given in tabular form. No specimens typifying Cactaceae names published by Willdenow in 1813 were located, but notes on some of these names, in particular on Cactus multangularis, are added. An index to Willdenow herbarium names of Cactaceae and current identifications is provided.
