Baden whitebeam ( Sorbus badensis )
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 ).
The Baden whitebeam is a shrub or small tree up to 10 meters high . It is very similar to the Franconian whitebeam ( Sorbus franconica ). The leaves are ovate-elliptical and 7 to 8 × 3 to 4 centimeters in size. The leaf base is rounded to broadly wedge-shaped, the leaf lobes pointed and incised up to 5 millimeters deep. The leaves have 9 to 10 pairs of lateral nerves. Their underside is yellow-green. The calyx is upright-inclined. The fruits are 12 × 10 millimeters in size, round to slightly pear-shaped and light red. The numerous lenticels are about 0.3 millimeters in size.
The Baden-Haw is in southern Germany in Maintal , Tauber Valley and in the land endemic . It usually occurs on shell limestone at an altitude of up to 300 meters. Their preferred locations are west-facing slopes in shady locations.
The Baden whitebeam was first described by Ruprecht Düll in 1961 .
