Syringa Syringa Syringa (lilac) is a genus of 12 currently recognized species of flowering woody plants in the olive family (Oleaceae), native to woodland and scrub from southeastern Europe to eastern Asia, and widely and commonly cultivated in temperate areas elsewhere. The genus is most closely related to "Ligustrum" (privet), classified with it in Oleaceae tribus Oleeae subtribus Ligustrinae. Lilacs are used as food plants by the larvae of some Lepidoptera species including copper underwing, scalloped oak and Svensson's copper underwing. They are small trees, ranging in size from tall, with stems up to diameter. The leaves are opposite (occasionally in
Plant identification Plant identification Plant identification is the process of matching a specimen plant to a known taxon. It uses various methods, most commonly dichotomous keys or multi-access keys. Plant identification has evolved over hundreds of years and depends to a large extent on what criteria and whose system is used. Plant identification implies comparisons of certain characteristics and then assigning a particular plant to a known taxonomic group, ultimately arriving at a species or infraspecific name. In the history of botany many large systems, useful at the time, were widely used for decades until superseded as taxonomic knowledge progressed. The study
