InterestRoystonea - honour of General Roy Stone (1836-1905), American army engineer in Puerto Rico. One of the species commonly called Royal Palm. Roystonea regia, however. is a similar but taller species of 'Royal Palm' more widely cultivated in the world. The genus is from Central America and the Caribbean, 12 species, with intermeduiates. The trunks give out an aqueous sound when slapped. R. olearacea has lealfets in two ranks, in other species e.g. R. regia, in 4, with every 2nd or 3rd leaflet on each side points up and droops down again, making the leaves more 'bushy-tailed'. The fruits is a souce of oil. In some parts of the Caribbean, especially Cuba, Roystonea leafbases are used for thatch, and the trees for timber, livestock feed, palmito (palm cabbage or heart-of-palm, the terminal bud is edible.).
