MYRTACEJE. 



233. Psidium Guajava Linn. Sp. PI., 470 ; Biol. Centr. Amer. Bot., I, 406. 



From the West Indies and Mexico to South Brazil. " This 

 handsome evergreen and useful bush should engage universal atten- 

 tion anywhere in warm lowlands, for the sake of its aromatic whole- 

 some berries, which attain the size of a hen's egg, and can be 

 converted into a delicious jelly. The pulp is generally cream col- 

 ored or reddish, but varies in the many varieties which have arisen 

 in culture, some of them bearing all the year round. Propagation 

 is easy from suckers, cuttings or seeds. This big shrub is easily held 

 under control in extra-tropic countries, but in the warmest and moist- 

 est tropical regions it may become irrepressible, as it spreads readily 

 from suckers, and gets disseminated by birds and cattle easily."
