However, in the meantime Batsch established the Violaceae, as a suprageneric rank under the name of Violariae (1802), and as the first formal description, bears his name as the botanical authority. Batsch included eight genera in this family. Although Violariae continued to be used by some authors, such as Don (1831) and Bentham and Hooker (1862) (as Violarieae), most authors, such as Engler (1895), adopted the alternative name Violaceae, proposed by de Lamarck and de Candolle in 1805, and later by Gingins (1823) and Saint-Hilaire (1824). With the establishment of higher suprafamiliar orders, which he called "Alliances", Lindley (1853) placed his Violaceae within the Violales. Historically, Violaceae has been placed within a number of orders since Lindley's treatment, principally Violales (Hutchinson, Takhtajan, Cronquist, Thorne) and the equivalent Parietales (Bentham and Hooker, Engler and Prantl, Melchior), although such placement was considered unsatisfactory, but also Polygalinae (Hallier) and Guttiferales (Bessey). Of these, that of Melchior (1925), within the Engler and Prantl system, has been considered one of the most influential. Molecular phylogenetics resulted in the Angiosperm Phylogeny Group (APG) places it as one of a large number of families within the eudicot order Malpighiales. Violaceae, as one of 42 families, is placed in a clade of 10 families within the order. Its place within the parietal clade reflects its earlier position in Parietales, those families with parietal placentation. There it forms a sister group to Goupiaceae. The Violaceae are a medium sized family with about 22–28 genera, and about 1,000–1,100 species. Most of the genera are monotypic or oligotypic, but the three genera "Viola" (about 600 species), "Rinorea" (about 250 species), and "Hybanthus" include 98% of the species with about half the species in "Viola", and more than three-quarters of the remainder in the other two genera. Many attempts have been made at an intrafamilial classification, but these have largely been artificial, based on floral characteristics.
