Pimelea congesta is a species of flowering plant in the family Thymelaeaceae and is endemic to Lord Howe Island in Australia. It is a shrub with rough bark, decussate, elliptic leaves and heads of white flowers.
Pimelea congesta is a shrub that typically grows to a height of up to and has tough, red bark. The leaves are closely overlapping, decussate, elliptic or narrowly lance-shaped, mostly long and wide on a petiole about long. The leaves are leathery, dull pale green, and glabrous. The flowers are white and borne in heads of about 9 flowers on the ends of branchlets. The sepals are white, egg-shaped, silky-hairy on the lower part and about long, the floral cup long and the stamens protruding from the floral tube. Flowering occurs from mid-July to mid-October and the fruit is a brown, elliptic nut long.[1] [2] [3]
Pimelea congesta was first formally described in 1872 by Charles Moore and Ferdinand von Mueller in Fragmenta Phytographiae Australiae from specimens collected by Moore on "the top of Mount Lidgbird and in other places on Lord Howe's Island".[4] [5] The specific epithet (congesta) refers to the congested inflorescence.
The species is endemic to Lord Howe Island where it is widespread, especially on exposed ridges. It is closely related to Pimelea longifolia of New Zealand.[3]
