Answered by: Nan Hampton

QUESTION:

I am trying to identify a tree that has a green rubbery look with long, sharp, green thorns. This tree is on my property in Conroe, TX and the soil type is Gladwater clay frequently flooded.

This sound like Poncirus trifoliata [syn. Citrus trifoliata] (trifoliate orange).  It is native to China and Korea and is considered invasive in North America.  Here are more photos and information.
