Sorbus vilmorinii Sorbus vilmorinii Sorbus vilmorinii, the Vilmorin's rowan or Vilmorin's mountain ash (), is a species of flowering plant in the family Rosaceae, native to Sichuan, Tibet and Yunnan in China. It is a deciduous shrub or small tree, tall, with ferny leaves, each having multiple leaflets that turn purple in autumn (fall). The fruits, which can last through winter, are crimson, turning to pale pink. They are eaten by birds when there is no other food supply nearby. The specific epithet "vilmorinii" refers to the 19th century French horticulturalist Maurice de Vilmorin. It grows in a wide range of habitats
Sorbus torminalis the bark on old trees. The species has sometimes been placed in its own genus, "Torminalis". Recent molecular phylogenetics confirms an earlier taxonomic opinion that the genus "Sorbus" as defined in the broad sense is not monophyletic, but the simple-leafed species traditionally included in "Sorbus" are a monophyletic group; this species would be included in a clade called "Aria" (genus "Aria" or "Sorbus" subgenus "Aria") as the species "Aria torminalis" Beck. It is a sexually reproducing diploid species that forms diploid and polyploid hybrids with members of subgenus "Aria" (whitebeams). A number of often very localised stable apomictic polyploid species
