The exact number of species is disputed depending on the circumscription of the genus, and also due to the number of apomictic microspecies, which some treat as distinct species, but others group in a smaller number of variable species. Recent treatments treat "Sorbus" in a narrower sense to include only the pinnate leaved species of
Sorbus anglica cliffs, quarries and rocky hillsides. It appears to be indifferent to soil pH. Occasional specimens are known from oak woodland. Research suggests Sorbus anglica developed from a cross between Sorbus porrigentiformis and Sorbus aucuparia. Sorbus anglica Sorbus anglica, the English whitebeam, is a species of whitebeam tree in the family Rosaceae. It is uncommonly found in Ireland and the United Kingdom, with an entire British population estimated at about 600 individuals.
