Male flowers in clusters or racemes of 2–4 flowers; peduncles to 5 mm; pedicels 2–4 mm long; petals 4–5 mm long, yellow. Female flowers solitary or paired; pedicels 3–8 mm long; petals 2–4 mm long, yellow.

Native to Africa, widely naturalised (e.g. southern Europe, U.S.A.). *CVU, *EGU, *Glep, *Gold, *GGr, *MuF, *MuM, *NIS, *VRiv, *Wim. Locally and seasonally common in paddocks and naturally open vegetation, roadsides etc., particularly in areas prone to occasional flooding (river banks, lake verges etc.).

Australian plants have often been treated as subsp. leptodermis Schweick., but recent molecular investigation (Shaik et al., 2016) has shown that our plants belong to the typical subspecies.
