Although Brahea and Washingtonia look similar and are found in close area, they are not closely related.
The flower stalks appear in late spring, between the leaves, much longer than them. This is a visible difference with the Washingtonias (California fan palms) that have the leaf stalks about the same length as the leaves, with the flowers barely sticking out outside the leaves.
