Zeltnera
Also called Zeltneras
Zeltnera is a genus of flowering plants in the gentian family. It was erected in 2004 when the genus Centaurium (the centauries) 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.
Plants of this genus are annual, biennial, or short-lived perennial herbs. They are taprooted or have fibrous root systems. They produce one or more branching stems which are often ridged and sometimes winged. The leaves are gathered around the lower stem or arranged along the length of the stem.
