GLEDITISIA, TRIPLE-THORNED ACACIA; a genus of the dicotia order, belonging to the polygamia class of plants. There is but one species, which rises with an upright trunk 30 or 40 feet high, branching out regularly with many long triple thorns, and closely garnished with doubly pinnated leaves, each leaf consisting often of near 200 smaller leaves or foliola. The flowers are amentaceous, and of a greenish colour proceeding from the sides of the branches, and succeeded by broad seed-pods near a foot and an half long.—This plant is a native of South America, but will thrive in this country in any situation. They are propagated by seeds, which are annually procured from America by the feedsmen.
