Coccothrinax clarensis

This species' name references the site at which it was first collected for cultivation, Santa Clara, California. It holds two subspecies: clarensis and brevifolia, and has been considered endangered internationally since 2016. This is due to its very unusual preference of soil composition, which is serpentine soil containing ultramafic rocks. These rocks make up the earth's mantle and is a rare element of topsoil except where magma has brought it to the surface.
