Zeltnera is a genus of flowering plants in the gentian family. It was erected in 2004 when the genus Centaurium was split. Genetic analysis revealed that Centaurium was polyphyletic, made up of plants that could be grouped into four clades. Each became a genus. Centaurium remained, but it is now limited to the Eurasian species. The Mexican species now belong to genus Gyrandra, and the Mediterranean and Australian plants are in genus Schenkia. The new name Zeltnera was given to this genus, which contains most of the North American centauries. There are about 25 species.
Centaurium scilloides, also known as perennial centaury is a flowering plant in the family Gentianaceae. It is native to Atlantic Europe and the Azores. Plants from the Azores have white flowers and are genetically different with some treating it as a different species.
Gyrandra is a genus of flowering plants in the family Gentianaceae, found in Texas, Mexico and Central America. Annual herbs, they are usually found in montane pine-oak forests.
