Coffee is grown in most of the warmer regions of Mexico and it is one of the 

 important agricultural products of the country. The most important states in 

 coffee production are Veracruz, Chiapas, Oaxaca, and Tabasco, but Veracruz is 

 reported to produce a larger amount than all the other states combined. The 

 shrub is said to have been cultivated first at C6rdoba. It is reported to be 

 abundant in the wild state in some parts of Veracruz. 



Coffea liberica Hiern, the Liberian coffee, also is cultivated in Mexico. It is 

 distinguished by having a 6 to 8-lobed corolla. It can be grown at lower levels 

 than C. arabica, and is more robust and productive.
