Notes on infraspecific nomenclature and classifications of cultivated plants in Compositae, Cruciferae, Cucurbitaceae, Gramineae (with a remark on Triticum dicoccon Schrank) and Leguminosae

In connection with revisions in cultivated plants, nomenclatural notes are published for selected Compositae (Cichorium, Cynara, Lactuca, Pterocypsela), Cruciferae (Brassica), Cucurbitaceae (Benincasa, Citrullus, Cucumis, Cucurbita), and Leguminosae (Vigna). The case of Triticum dicoccon Schrank (1789) is discussed after newly published arguments questioning the validity of the publication of this species by Schrank.
