About

Pimelea spinescens, commonly known as plains rice-flower, spiny rice-flower or prickly pimelea, is a species of flowering plant in the family Thymelaeaceae and is endemic to Victoria. It is a spreading undershrub with elliptic leaves arranged in opposite pairs, and heads of white, cream-coloured or yellow flowers surrounded by 4 elliptic, leaf-like involucral bracts.

Where it grows

Subspecies pubiflora was thought to be extinct since it had not been collected since 1901, but was rediscovered in 1980, growing in grassy woodland in the Wimmera region of Victoria. Subspecies spinescens grows mainly in grassland and open shrubland between Melbourne, Horsham and Echuca.
