Order LIV. MYRTACEE. 
Myrtacee, Benth. et Hook. Gen. Plant. i. p. 690. . 
A large order of trees and shrubs, comprising about eighty genera and nearly 2000 
species. Two tribes are almost exclusively restricted to Australia and neighbouring 
islands, and include upwards of forty genera and 650 species. The Myrtee and 
Lecythides combined are even more numerous in South America as to species; and 
there is also a considerable number in Tropical and Subtropical Asia. About a dozen 
species are found in the whole of Africa; and one is a native of the south of Europe. 
In America none is found north of Mexico and South Florida. 
Tribe MYRTEA. 
This tribe is generally diffused, but by far most numerous in South America. Berg 
(Flora Brasiliensis, xiv. pars 1) estimates the number of American species of this tribe 
at 1630; but he appears to have unduly multiplied them, and many of the following 
can only be considered slight varieties.
