Washingtonia filifera. CALIFORNIA FAN PALM. Southern California
PALMAE (Palm family)

Stouter and shorter than the much more common Mexican fan palm and hairier on the leaf margins. Specimens can be seen in six islands of the Inner Quad. In Palo Alto, the three specimens at 918 Moreno Avenue can easily be compared to the Mexican fan palm nearby at 924 Moreno.
