意味（1）

A type of round shield borne by ancient Greek soldiers

shield both large and tough has never said that aspides are small and weak […]

意味（2）

(archaic) An asp or generic venomous snake

Flesh dipped in the sea Ægeum will never be sweet; the herb Trigion being once bit with an aspis never groweth, and conscience once stained with innocent blood is always tied to a guilty remorse.

意味（3）

(palynology) A prominent ring of thickened exine around a pore on a pollen grain

As might be expected, characters of the aspides themselves are not of much value in pollen identification, but they are easily recognized and many three-pored, aspidate grains are broadly categorized as betuloid in studies of airborne pollen.
