Small evergreen tree or large shrub with ovate or elliptic leaves. The stiff branches have spines at the leaf axils. Creamy white flowers, often purple tinged in bud. Large fragrant fruits with leathery, bumpy yellow skin over a very thick white rind that is difficult to separate from the fleshy pulp.

Well drained soil in an area with a warm, preferably moderate climate. Short periods of frost may be tolerated, but will damage leaves and fruit. Can be grown in a conservatory.
Prune in early spring if required.

From cuttings. May also be grafted or budded.

Edible, mostly the peel is used for flavouring or preserves. Traditionally used for various medicinal purposes.

other notes:
Probably native to Southeast Asia, but long cultivated in other areas.

Thought to be one of the oldest forms of cultivated citrus, known for at least 6,000 years. The species name derives from the ancient state of Media, part of Persia.
