A tree 40 — 60 feet high, 1 — 2 in diameter, armed on the trunk and 
branches with spinous processes, (aculei properly which adhere only to the 
bark) sometimes simple but very commonly bearing two lateral spines near 
the summit. Leaves equally and compoundly pinnate. Leaflets very nu- 
merous, small, oval, slightly crenulate, glabrous. Flowers small, in small 
axillary racemes. Calyx 6 — 8 leaved, 3—5 leaves interior, all oval lance- 
olate, pale green. Legumen or pod somewhat oval oblique, compressed,
