I doubt that jocularity was the intent, but it does seem a daunting
challenge. Here in the Southland of the United States, we encounter a tree
that is referred to in the local vernacular as a "Thorny Locust". Wotever
its real name is unknown to me.

May be the Honey-Locust, Gleditsia triacanthos. (But I don't know
whether any of the other species of this genus occur in North America.)
There is a spineless cultivar, G. t. 'Inermis'.
