1. A tropical Asian grass (Cymbopogon nardus) having bluish-green, lemon-scented leaves and an essential oil.

[New Latin, from French citronnelle, lemon oil, diminutive of citron, citron. See citron.]

A tropical grass, Cymbopogon nardus, from the leaves of which oil of citronella is distilled. This essential oil is pale yellow, inexpensive, and much used in cheap perfumes and soaps. It is perhaps best known as an insect repellent. A large acreage is devoted to the cultivation of this grass in Java and Ceylon. See also Cyperales.

Lemon-scented tropical grass Cymbopogon nardus used in salads and dressings; the essential oil is also used as an insect repellent.

Citronella's powerful lemony aroma makes it particularly useful as an air freshener or insect repellent. Its deodorant and stimulating qualities are excellent for tired, sweaty feet. It is also used in the treatment of excessive perspiration, fatigue, headache, oily skin, and as an insect repellent.
