Its fruit has either a spongy or leathery rind with a juicy pulp that is divided into sections. The fruit is indigenous and widely cultivated in the Philippines (Tagalog: calamansi or kalamansî (kɐlɐmɐnˈsɪʔ); Visayan: limonsito or simuyaw), Calamansi is available year round in the Philippines and is usually seen in its unripened state as a dark green fruit, but if left to ripen it turns a tangerine orange color.
