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]
