Oligochaeta is a genus of Asian flowering plants in the tribe Cardueae within the family Asteraceae.[2][3][4]
Oligochaeta is native to central, southern, and southwestern Asia. They are annual plants that grow in mountain and steppe habitat.[5]
It is part of the "Rhaponticum group" in the tribe Cardueae, along with the genera Callicephalus, Leuzea (including Acroptilon and Rhaponticum), Myopordon, and Ochrocephala.[6] It can be distinguished from other genera by its pollen.[7]
