Torminalis is a genus of plants in the rose family, Rosaceae.[2] The genus was formerly included within the genus Sorbus as the sectionTorminaria, but the simple-leafed species traditionally classified in Sorbus are now considered to form a separate monophyletic group.[3] It is monotypic, being represented by the single species Torminalis glaberrima, commonly known as wild service tree, chequers, and checker tree.[4] This tree is native to Europe, parts of northern Africa and western Asia.
A possible second species in the genus has been identified through DNA analysis, but a new scientific description for it has not yet been written.[5]
