Rosidae

Under the International Code of Nomenclature for algae, fungi, and plants (ICN), Rosidae is a botanical name at the rank of subclass.

Under Phylocode, Rosidae is a clade defined as the most inclusive crown clade containing Rosa cinnamomea,[1] but not Berberidopsis corallina nor Dillenia indica nor Gunnera manicata nor Helianthus annuus nor Saxifraga mertensiana nor Stellaria media nor Viscum album.

[3] The Phylocode definition includes Crossosomatales, Geraniales, Myrtales, Fabidae (Celastrales, Cucurbitales, Fabales, Fagales, Huaceae, Oxalidales, Malpighiales, Rosales and Zygophyllales), Malvidae (Brassicales, Huerteales, Malvales, and Sapindales) as they are defined in the APG III system.

[4][verification needed] This definition was formulated in 2007, and is agnostic on the inclusion or exclusion of Picramniales and Vitales.

[6] The position of Picramniales as sister to Malvidae sensu stricto requires it to be included among the rosids.
