What are the morphological characteristics of this plant?
Murraya koenigii has pinnately compound leaves consisting of 11 to 21 small, lanceolate leaflets that are dark green, glossy, and arranged in opposite pairs along a central rachis. The leaflets typically measure between 1 and 3 centimeters in length and feature entire margins with acute tips. The plant is a perennial shrub or small tree that can reach heights of up to 4 meters in optimal conditions. Its woody stems are often branched and can exhibit a slightly grayish bark texture as the plant matures. Small, white, fragrant flowers emerge from the axils, eventually giving way to small, black, fleshy drupes.
What is the geographical distribution of this plant?
This plant is native to the Indian subcontinent, specifically spanning across India, Sri Lanka, and parts of Southeast Asia. It thrives primarily in tropical and subtropical regions where the climate remains warm and humid throughout the year. In its natural habitat, it is often found growing in well-drained soils along the edges of forests or in open scrublands. While its origins are centered in South Asia, it has been widely introduced to other tropical regions around the world for culinary and medicinal purposes. Because of its adaptability, it can be found cultivated in many gardens and agricultural zones globally.
