(Click on the underlined title to see more)Brahea brandegeei, a less robust replacement for the very common 'tall skinny telephone pole' palm(Washingtonia robusta - Mexican Fan Palm), which it can very much resemble, depending on the 'strain/type-lineage' of B. brandeegii, but grows much more slowly,  about half as slow.  In the photo it's the palm in the middle with the old leaves 'petticoat' along trunk.  It's about 25 to 30 feet tall, and probably 50 years old. Native to Baja Sur and Sonora Mexico. Grows to around 40 to 60 feet, potentially more.   Also looks like a narrower and taller version of Brahea edulis(included in IslandNativesBlog), but with some serration on leaf stems/petioles, and, with leaf bases that tend to stay attached to the trunk unless taken off by cutting, whereas B. edulis leaves will slough-off on their own or are easily pulled off after dying, and the petioles are thornless/serrationless.  Palm at right is Butia capitata - Jelly Palm, and palm at left is probably Phoenix rupicola.  Rolando neighborhood, west La Mesa.
