PlantFiles: Calappa Palm
Actinorhytis calapparia

Though this plant is rated as a 10a plant, that is Florida 10a, not California 10a.. In California it does not even appear to like growing in 10b, but some can make it survive a winter or two. It struggles with prolonged cold and is really not a palm for anywhere but the humid tropics or humid subtropics.

Very fast growing palm. Forms a crown of strongly recurving leaves, somewhat similar to Carpentarias. Seed, however, is enormous relative to Carpentaria seed. Crownshaft is pale yellow. From New Guinea
