Excellent!
It looks like the oak is playing host to a number of different kinds of grape vines. The way the trunk is thin and long and the leaves large and upright is a good parallel to the way many of the herbal oak/ivy-themed images are drawn.
I notice the tree in Casanatense is explicitly identified as an oak tree (Quercus arbore).
I have a feeling the host-shrub in Egerton 747 is something other than oak (it looks more like Hawthorne or something smaller and shrubbier), but one can see how a later illustrator might interpret it (or re-invent it) as oak.
