Quercus x sternbergii & Quercus x introgressa
These are two hybrids I've seen discussed here that I'd give a left appendage to get a hold of!!
Q. x sternbergii, a shumardii/buckleyii hybrid, was named for the famed Guy Sternberg. I emailed Guy once, and he indicated he no longer sells acorns due to the difficulty of keeping up. Can anyone here (Dax? IIRC has posted about this tree) tell me a source of this tree, or some acorns from it (I realize they'd be F2 & possibly recrossed w/something). Honestly I'd prefer just the acorns.
The other is the Concordia oak from a small area of Missouri...a three way cross of Q. bicolor, Q. prinoides, and Q. muehlenbergii...does anyone know a source for this one? Preferably acorns but seedlings OK too.
