in Botany, the name of a species of calyx, consisting of valves, and hanging down in different Amentum, ferent directions from the caulis. Common oats afford Amerade, a good example of the amentum.

in Roman Antiquity, a thong tied about the middle of a javelin or dart, and fastened to the fore finger, in order to recover the weapon as soon as it was discharged. The ancients made great use of the amentum, thinking it helped to enforce the blow. It also denotes a latchet that bound their sandals.
