1- Introduction to the Subfamily Myrtoideae
1.1- Overview The family Myrtaceae has two subfamilies: 1- Subfamily Myrtoideae (about 75 genera). 2- Subfamily Leptospermoideae (about 80 genera). The subfamily Myrtoideae are found worldwide in subtropical and tropical regions, with centers of diversity in the Neotropics, northeastern Australia, and Malesia. Subfamily Myrtoideae (about 75 genera) was recognized as having fleshy fruits and opposite, entire leaves. Most genera in this subfamily have one of three easily recognized types of embryos. The genera of Myrtoideae can be very difficult to distinguish in the absence of mature fruits.
