Thrinax ekmaniana is a palm which is endemic to Cuba. Only a single population of less than 100 mature individuals remains in the wild. It is an endemic palm of Mogotes de Jumagua in northern Cuba. This absolutely unique little treasure survives only on three of the small mogotes where it was rediscovered in 1978 by a Group of paleontologists and naturalists looking for fossils in the caverns and cataloging the fauna and flora of these small mountains (Sabaneque Speleological Group). A small number under 100 individuals cling to the steep cliffs. The Jumagua Palm has a gray trunk about 5 cm in diameter holding a spherical and very dense crown of stiff, spiky light green leaves that have almost no stalks and therefore sit very close together.
