What is "acronychia"

Acronychia is a genus of 44 species of plants, mainly shrubs, in the rue family Rutaceae. They have a broad distribution covering China, Southeast Asia, India, Malaysia, Indonesia, Australia and the islands of the western Pacific Ocean.

Like all members of the Rutaceae, the plants contain aromatic oils and the leaves are aromatic when crushed.

In Australia, which has 19 species, they are often called aspens though they are not closely related to the true aspen. Two rare Australian species are Acronychia baeuerlenii and Acronychia littoralis.

A medicinally important, widely spread and common species of the tropical forests of South and Southeast Asia is the small tree Acronychia pedunculata.
