    Where’s the “Like” button when we need one? The acorns are beautiful, and those two leaf shapes on the same branch were so surprising.

    How is it holding up with SOD?

    I wonder if the spinose leaves on the terminal branch are first- or second-flush leaves? It’s not unusual for oaks to have two (even three) flushes in a single growing season (e.g., willow oak and pin oak in the eastern U.S.) with the later flushes showing marked morphological differences when compared to first flush leaves on the same branch. Because canyon live oak is an evergreen species, having older leaves is expected. But in the evergreen oaks I know in the east, there are not such pronounced differences from one year to the next.

    How interesting about young and mature leaves.

    As far as I’m aware there is only one example of this species in Australia. I have been procrastinating for v30 years to go and see it 🙂 Time to pull the finger out!

    Great entry– love the photos (golden velvet capped acorns!) and the poetic descriptions! Thank You!


    The photos and citations are wonderful. Another example of nature adapting to its environment. The leaf formations are particularly interesting as we on the East Coast of the U.S. are used to large and elongated shapes.

    One can surmise that the spinous feature of first flush leaves in Quercus chrysolepis may have been an early adaptation to deter such hungry early herbivorous mammals as: deer, antelope, sloths, camels, horses, several rodent species, etc. which have a 50+ million year history in California, as do several oak species, living throughout the Cenozoic Era, as shown by the fossil record found at several museums throughout CA. Also we need to appreciate the keen eyes, beautiful writing, and unstinting conservation efforts of John Muir, remembering how he convinced President Teddy Roosevelt to preserve Yosemite as a National Park. Thanks for the excellent photographs.
