This shrub was just standing out by itself at the edge of a field at Holdenwood

I came across this shrub the other day as I was walking around the Holdenwood estate in Shirley. I don’t recall seeing one quite like it before. It was about 6 feet tall, with a sturdy trunk, about 4 inches in diameter, hidden in the middle of all those leaves. The branches were thin and vine-like, spraying out from the top of the trunk.

The leaves were a dark olive-green on one side, slightly yellow-green on the underside, and had a very rubbery feel to them. The veins were very pronounced, showing almost reddish on the underside. It looks like some type of gum tree, like a tupelo, only more of a shrub.
