Roystonea stellata is an extinct species of palm endemic to Yagruma terrace in the Maisí region of Guantánamo Province in eastern Cuba. The species is known from only a single collection made by French-born botanist Frère León in 1939.
Roystonea stellata was a large palm which reached heights of 15m (49feet). The 95cm (37inches) inflorescences bears white male and female flowers. Fruit were 9.8- long and 7.8mm8.5mm wide, and black when ripe. The single known collection is not complete enough for a complete description.[1]
No specimens have been found in repeated surveys of its habitat since the 1990s, and thus R. stellata is probably extinct.[2]
