Acronychia is a genus of about fifty species of plants in the rue family Rutaceae. The leaves are simple or pinnate, and the flowers bisexual with four sepals, four petals and eight stamens. They have a broad distribution including in India, Malesia, Australia and the islands of the western Pacific Ocean. About twenty species are endemic to Australia.
Plants in the genus Acronychia are shrubs or trees with simple or trifoliate leaves arranged in opposite pairs and with oil glands in the leaves. The flowers are arranged in leaf axils either singly or in cymes or panicles. The flowers are bisexual, with four sepals, four petals and eight stamens. The petals are free from each other, as are the stamens. The stigma is small, not differentiated from the style, the fruit is a drupe and the seeds are black.[2][3]
The genus Acronychia was first formally described in 1775 by Johann Reinhold Forster and Georg Forster in their book Characteres Generum Plantarum.[4][5] The first species they described, the type was Acronychia laevis.[4]
Some species have common names including the word "aspen", a name also applied to some Northern Hemisphere plants in the genus Populus in the family Salicaceae.[6]
The following is a list of species accepted by Plants of the World Online as at June 2020:[7]
The best known species of Acronychia is probably A. acidula due to its promotion as a food plant.[8]
