Guava (from Arawak via Spanish, Guayaba) is a genus of about 100 species of tropical shrubs and small trees in the myrtle family Myrtaceae, native to Mexico, the Caribbean, Central America and northern South America. The leaves are opposite, simple, elliptic to ovate, 5-15 cm long. The flowers are white, with five petals and numerous stamens. Psidium species are used as food plants by the larvae of some Lepidoptera species including Eupseudosoma aberrans, Snowy Eupseudosoma and Hypercompe icasia. In Malay language it is called as Jambu. As for green guava. it is being called as Jambu Batu(literally "Rock or Stone Guava") due to the hard-to-chew of its kernel and contents. As for pear-shaped pink coloured guava in South East Asia, it is called as Jambu Air(literally "Watery Guava") due to its watery kernel and contents when consumed.
Strawberry Guava Psidium cattleianumThe fruit is edible, round to pear-shaped, from 3-10 cm in diameter (to 12 cm in some selected cultivars). It has a thin delicate rind, pale green to yellow at maturity in some species, pink to red in others, a creamy white or orange-salmon flesh with many small hard seeds, and a strong, characteristic aroma. It is rich in vitamins A, B, and C (a guava fruit contains more vitamin C than a typical citrus fruit – the rind contains over five times more vitamin C than an orange). It also contains high amounts of calcium – which is unusual in a fruit.
