Tbe common wild form, cultivated in Europe at least since 
1696. According to Mr. Fawcett, though it grows near 
the Kingston gardens, at an elevation of 680 ft., it is more 
commonly found in Jamaica between 2,000 and 5,000 ft. 
above sea-level, whereas in the United States it is a seaside 
plant or of the coast lowlands, and never found far above 
sea-level.
