What is the meaning of Guava?

A tropical tree, or its fruit, of the genus Psidium. Two varieties are well known, the P. pyriferum, or white guava, and P. pomiferum, or red guava. The fruit or berry is shaped like a pomegranate, but is much smaller. It is somewhat astringent, but makes a delicious jelly.
