Taxonomy

new leaves of Psidium in West Bengal, India.

This genus was described first by Linnaeus in 1753.[4][5] Many of the species bear edible fruits, and for this reason several are cultivated commercially.[6] The most popularly cultivated species is the common guava, Psidium guajava.

Fossils are known from the Paleogene of Patagonia.[7]
