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]
