Hi,
I tend to agree with Brian. QA seems to have a little more dramatic definition to the inter-point leaf arcs...
And yet, I have seen a wide spread of characteristics on quercus agrifolia, for example, between those that are native to inland valleys vice those that flourish on the coast [like at Ft. Ord, where I work]. Ft. Ord, btw, is a BRAC'ed army camp a little larger in area than San Francisco and packed with yamadori-potential QAs, cypress, and junipers.
I had one QA taken from my Los Altos Hills yard [squirrel volunteer] that had deep-green leaves and a light bark. Most unusual. OTOH, maybe it wasn't QA at all [although that's about all that grew in proximity, so those were the prevalent acorns].
So, any guesses as to genus?
Finally, Joanie, your cork oak rocks! So must your husband. Two winners.
Thanks,
Vickie
