Common Name: Kalamansi
Scientific Name: Citrofortunella Microcarpa

Kalamansi is a smooth and slightly spiny plant, growing to a height of 3 to 5 meters. Leaflets are elliptic to oblong-elliptic, 4 to 8 centimeters long. Petioles are very narrowly or scarcely winged, about 1 centimeter long. Flowers are axillary, solitary, rarely in pairs, white, and short-stalked. Fruit is yellow when ripe, nearly spherical, 2 to 3.5 centimeters diameter, 6- to 7-celled, and thin-skinned. The skin or peel is green to yellowish green or yellow, loosely adhering to the flesh. The flesh contains a few light orange seeds.

Essential Oils / Whole Fruit and Peel: Study evaluated the volatile constituents of calamondin peel or whole fruit by cold pressing, steam distillation, or hot water treatment. Hot water heating increased the yields of essential oils from both whole fruit and peel. Whole fruit oil yielded higher levels of monoterpene alcohols, such as linalool, terpinen-4-ol, and a-terpineol, which may contribute to the aroma profile of fruit tea. Peel oil yields higher contents of sesquiterpenes, such as germacrene D.
