Oaks from acorns collected by Allan Taylor. These are some of the ones that were grown on as plants at Timberline Nursery in Arvada, Colo.
First is Quercus vaccinifolia collected on Scott Peak in (I guess) the Siskiyous.
Second was labeled "unknown quercus" (a label like that, and it's mine ....). It's clearly Q. vaccinifolia crossed with Q. chrysolepis.
Next two are Q. undulata x Q. arizonica.
