Pungous Onion is a magical plant comprised of a swathe of green leaves and an orange elongated bulb at the base. It is very pungent and, because of this, contact with freshly chopped Pungous Onions is disadvised. Chopping these onions seems to create an eye irritation that makes one cry.
Pungous presumably derives from the Latin pungo, meaning to prick or to sting, or perhaps more directly from its English descendant pungent, meaning having a strong odour or taste, as in spicy or acidic food.
