Trachymene ochracea (common names white parsnip, wild parsnip, yellow parsnip) is a herb in the family Araliaceae.[3] It is native to Australia and found in New South Wales and Queensland.[3]

Description

Trachymene ochracea is an erect herb growing up to 75 centimetres (30 in) high. The leaves are consist of 3-5 deeply dissected lobes on stalks (petioles) up to 10 cm long. The inflorescences are umbels borne on dichasial cymes. The umbels have 30 to 60 flowers, are from 7 mm to 18 mm in diameter on stalks (peduncles) which are 3 to 8 cm long and are glandular-hairy near the stalk base. The flowers are bisexual, with white petals (pink in bud). The ovary has two locules.[3]

The plant is prolific after rain, growing in mulga and mallee communities on red earths and on sand.[3]

The species epithet, ochracea, is the Latin adjective, ochraceus,-a,-um which means "ovhre-yellow" or "yellowish-brown".[4]
