I believe this is an example of Zanthoxylum clava-herculis, due to the terminal panicles vs the small auxillary clusters of fruit of Zanthoxylum americanum. I can\'t say for certain it is Z. clava-herculis, but it doesn\'t resemble Z. americanum, which grows everywhere around me. Here is an example of how Z. americanum fruits and flowers.. Small clusters close to the thorns. I will try to get a better picture next time I\'m out.
