Systematics

Taraxacum sect. Ceratoidea includes six to eight species centred in the western part of Middle Asia (Uzbekistan, Turkmenistan) and Iran and Afghanistan. Sexuals dominate. Typical habitats of the members of this section are permanently to periodically wet saline sites, often along streams or near springs. The section holds a rather separate position within the genus; T. sect. Macrocornuta is the section closest to it, but is less specialized ecologically and more derived morphologically.
