''Stylophorum'' ( celandine-poppy) is a genus of three species of herbaceous perennial plants native to woodland in eastern North America and China. Stems are bristly, and leaves are lobed and have wavy edges. Flowers are yellow and have four petals and an unusually long style, for which the genus is named. Several may be found on each stem. The closely related '' Hylomecon vernalis'' has only one flower on each stem, and the greater celandine (''Chelidonium majus'') has branched stems and no bract In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale.

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
