Hypochaeris (sometimes spelled Hypochoeris) is a genus of plants in the family Asteraceae. Many species are known as cat's ear. These are annual and perennial herbs generally bearing flower heads with yellow ray florets.
Estimates of the number of species range from about 50 [1] up to about 100.[2] Most species are native to South America, but some are found in Eurasia and North Africa. Species include:
- Hypochaeris achyrophorus
- Hypochaeris brasiliensis
- Hypochaeris ciliata
- Hypochaeris elata
- Hypochaeris glabra - Smooth Cat's-ear
- Hypochaeris maculata - Spotted Cat's-ear
- Hypochaeris oligocephala
- Hypochaeris radicata - Common Cat's-ear
- Hypochaeris robertia
- Hypochaeris scorzonerae
- Hypochaeris sonchoides
- Hypochaeris sessiliflora
- Hypochaeris stuebelii
