His main work, ''Die Agaven'', published in 1915, described 274 species of agave, divided into 3 subgenera, ''Littaea'', ''Euagave'' and ''Manfreda''. He also recognised a new genus of cactus, ''Roseocactus'', in 1925.
The genera ''Bergerocactus'' (''Cactaceae'') and ''Bergeranthus'' (''Mesembryanthemaceae'') are named in his honour.
