Coccothrinax proctorii

[4] 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.

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.

Indoors it also makes a neat bonsai, that can even be cultivated just on a piece of coral limerock, practically without soil.

[5] 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.

In a century, the population will have likely declined to only about 123,500 individuals, all restricted to protected areas.
