==Description== A medium-sized palm, with a slender trunk, and an open crown, of deeply divided leaves, with nearly perfectly symmetrical divisions, dark green above, and silvery white below. The trunk type is solitary.
== Horticulture == It prefers a sunny, moist, but well-drained position. It is salt tolerant, and prefers an alkaline soil with a position in full sun, or light shade, in a tropical or subtropical climate, and once established, can endure quite a bit of coastal exposure. While slow growing, it can be grown on just coral limerock. Indoors it also makes a neat bonsai, that can even be cultivated just on a piece of coral limerock, practically without soil.<ref>{{Cite web|url=http://www.palmpedia.net/wiki/Coccothrinax_proctorii|title = Coccothrinax proctorii - Palmpedia - Palm Grower's Guide}}</ref>
== Conservation == It is considered Endangered by the IUCN Red List, having declined to about 435,699 mature individuals in 2000 from a projected original population of 600,000. This population has still continued declining, and the projected 2013 population is around 428,500 mature individuals. In a century, the population will have likely declined to only about 123,500 individuals, all restricted to protected areas.<ref name="Fairchild" />
