Senecio inaequidens, known as narrow-leaved ragwort[3] and South African ragwort,[4] is a species of flowering plant in the daisy family Asteraceae.


Senecio inaequidens is a perennial herbaceous plant about 80cm high, with practically hairless stems and leaves. The leaves are linear, entire or almost so and without petioles. The flower heads are capitula with yellow ligules (ray florets) about 10mm in length.[5]:763


It is a native species in the Afrotropic ecozone, specifically in Southern Africa: Lesotho, South Africa, Swaziland.[6]

In a European country like Norway it is considered as "alien" and a "threat against biodiversity". In 2010 it was discovered in Oslo, to the authorities' dismay.[7]
