Pimelea ligustrina is a species of flowering plant in the family Thymelaeaceae, and is endemic to south-eastern Australia. It is a shrub with lance-shaped or narrowly elliptic leaves arranged in opposite pairs, and clusters of creamy-white, white or pinkish flowers usually surrounded by 4 or 8, greenish to reddish brown involucral bracts.
Pimelea ligustrina is a shrub that typically grows to a height of and has stems. Its leaves are arranged in opposite pairs, lance-shaped with the narrower end towards the base or narrowly elliptic, mostly long and wide on a short petiole. The flowers are bisexual or female, creamy white or white, rarely pink, and arranged in large, erect clusters, surrounded by 4 or 8 lance-shaped to broadly elliptic involucral bracts long and wide. The floral tube is long, the sepals long and hairy on the outside. Flowering time varies with subspecies. The fruit is green and long.
Pimelea ligustrina was first formally described in 1805 by French naturalist Jacques Labillardière in his Novae Hollandiae Plantarum Specimen.
In 1983, S. Threlfall described three subspecies of P. ligustrina in the journal Brunonia and the names are accepted by the Australian Plant Census:
This pimelea occurs in the A.C.T. and all states of Australia, except Western Australia. Subspecies ciliata grows in forest, snow gum woodland and heath above south from the Brindabella Range in New South Wales, the A.C.T. and eastern Victoria. Subspecies hypericina grows on the margins of wet forest and rainforest, mainly between the Gibraltar Range and Mount Cambewarra in New South Wales. Subspecies ligustrina is widely distributed in forest below in south-east Queensland, eastern New South Wales, the A.C.T., southern Victoria, the far south-east of South Australia, and in Tasmania.
This pimelea is a food plant for caterpillars of the yellow-spot blue butterfly.
Subspecies ciliata is listed as "endangered" under the Victorian Government Flora and Fauna Guarantee Act 1988.
