I have been given a number of acorns for a hybrid oak that I am told takes back to the 1800's. It is called a Compton Oak Quercus xcomptoniae. I am trying to find out as much as I can about this hybrid species. Can anyone point me towards any information? All of my internet searches so far reference a 270 year old oak that was felled in Beaumont Texas during Rita, and a PDF of a tree walk in Georgia that mentions that they have one. I am told the hybrid is fast growing and deciduous. The acorns are odd looking in that the "cap" covers very nearly the entire nut (2/3+) and vaguely resembles a small fir tree cone (spikey) more than an acorn cap. I am told that the hybrid was probably a cross between a live oak and a water oak but I'm unsure of that. I am also told that the cross was patented back in the 1800's but patent searches for patents that old are difficult because the database has not been built that far back.
