''Torminalis'' is a plant genus that has sometimes been included within the genus ''
Sorbus'', as
Section ''Torminaria''. It includes at least one species, ''Torminalis clusii'' (Schönb.-Tem.) K.R.Robertson & J.B.Phipps (=''
Sorbus torminalis''). The species originally described as ''Sorbus orientalis'' is either considered to be a synonym of ''T. clusii'', or to be a second species, ''Torminalis orientalis'' (Schönb.-Tem.) K.R.Robertson & J.B.Phipps.
Taxonomy
It has recently become clear that the simple-leafed species traditionally included in ''Sorbus'' form a
monophyletic group, and the species of ''Torminalis'' could be included in a
clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, ...
called ''Aria''
(=genus ''Aria'' or ''Sorbus'' subgenus
''Aria'').
