The Baden whitebeam ( Sorbus badensis ), also known as the Baden bastard whitebeam or Baden bastard wildberry , is a small species from the complex of the bastard whitebeam ( Sorbus latifolia group). Like most other bastard whitebeams, it is apomictic , i.e. reproduces asexually through agamospermia . This species was hybridogenic, with the service of the service tree ( Sorbus torminalis ) probably also the Greek whitebeam ( Sorbus graeca ).
