Tea is made from the leaves of a shrub long cultivated in 

 China and Japan, and now also in India, Ceylon, and elsewhere.

 berries with a very hard seed. In the arid portions of Africa 

 and northwestern Asia, where they grow, they are of the first 

 importance as food. Successful attempts are now in progress 

 to introduce the culture of the date palm into the desert regions 

 of the extreme southwestern United States.
