Roystonea is a genus of eleven species of monoecious palms, native to the Caribbean Islands, and the adjacent coasts of Florida and Central and northern South America. Commonly known as the royal palms, the genus was named for Roy Stone, a U.S. Army engineer. It contains some of the most recognizable and commonly cultivated palms in tropical and subtropical regions.
Roystonea is a genus of large, unarmed, single-stemmed palms with pinnate leaves. The large stature and striking appearance of a Roystonea palm makes it a notable aspect of the landscape. The stems, which were compared to stone columns by Louis and Elizabeth Agassiz in 1868, are smooth and columnar, although the trunks of R. altissima and R. maisiana are more slender than those of typical royal palms. Stems often are swollen and bulging along portions of their length, which may reflect years where growing conditions were better or worse than average. Leaf scars are often prominent along the stem, especially in young, rapidly growing individuals. Stem color ranges from gray-white to gray-brown except in R. violacea, which have violet-brown or mauve stems. The largest royal palm, R. oleracea, reaches heights of 40 metres (130 ft), but most species are in the 15 to 20 m (49 to 66 ft) range.

The Royal Palm is a breed of domestic turkey. One of the few turkeys not primarily selected for meat production, the Royal Palm is best known as an ornamental bird with a unique appearance, largely white with bands of metallic black. Primarily kept as an exhibition bird, or on small farms, it lacks the size for large scale commercial use. Toms usually weigh 16 to 22 lbs and the hens 10 to 12 lbs.
A relative newcomer among turkey breeds, the bird first appeared in the 1920s on a farm in Lake Worth, Florida, apparently as a cross between Black, Bronze, Narragansett, and native turkeys. Years of selective breeding followed to stabilize the coloring, and the Royal Palm was finally accepted by the American Poultry Association's Standard of Perfection in 1971. In Europe, a turkey with similar coloration is sometimes called the Cröllwitzer, Pied, or Black-laced White.
Along with the decline of most heritage turkey breeds after the adoption of the Broad Breasted White by the turkey industry, Royal Palms are a very endangered breed today. The breed is classified as being on "watch" status with the American Livestock Breeds Conservancy. It is also included in Slow Food USA's Ark of Taste, a catalog of heritage foods in danger of extinction. The Australian and United States both report the breed as Endangered to the Food and Agriculture Organization of the United Nations.
