Gleditsia triacanthos.

Botanical name: 

Gleditsia triacanthos Linn. Leguminosae. Honey Locust.

North America. This tree, native of the region about the Mississippi and its tributaries, is cultivated as an ornamental tree both in this country and in Europe. The pods contain numerous seeds enveloped in a sweet, pulpy substance, from which a sugar is said to have been extracted. Porcher says a beer is sometimes made by fermenting the sweet pods while fresh.
