Myrciaria floribunda, commonly known as cambuizeiro, guavaberry or rumberry, is a species of plant in the family Myrtaceae.

It can be found across South and Central America and the West Indies in dry or moist coastal woodlands, up to 300 metres above sea level.

Guavaberry trees are slow growing and can reach 12–20 metres (39–66 ft) tall.

The fruit, which are roughly half the size of cherries, are yellow-orange, dark-red, or purple with tanginess of a guava containing a small amount of translucent flesh surrounding a stone.

[5] There is great genetic variability within the species, and Myrciaria floribunda can vary in form, structure and appearance, and that has given rise to a large number of botanical synonyms.
