The 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 5,000ft. 

 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.

A garden form with the leaves green at center, bordered and striped 

 with various shades of yellow and white, and often tinged with red at 

 least when young. No doubt separable into at least three forms capable 

 of being fixed by selection: one with yellow margin, one with added 

 white stripes, and one with a fairly persistent additional tine of red on the 

 back near the border.
