About Sabal causiarum
This species is one of the taller species in its genus. It is a solitary palm with a stout, smooth gray trunk. The crown is topped with a dense canopy of up to 40 leaves. The leaves are deep green in color and are deeply divided to about half their length into several segments which may droop at the ends. Unlike other species in its genus, as the older leaves turn brown and die off, they all off. Many Sabals tend to retain a skirt of old leaves that cover the trunk. The inflorescences are long, arching and branched. The flowers are creamy white. The small round fruit turns black as it ripens.
