Morphology

pennycress = penny + cress (transparent) = penny + cress

A straightforward compound of 'penny' + 'cress': it denotes a kind of cress associated with small, round seedpods, so the plant sense is directly derived from its parts.

Etymology

Pennycress comes from two simple words: penny (a small 'coin') and cress (a peppery 'plant'), because its flat, round seed pods look like tiny coins on a cress-like plant. So pennycress is a small plant named for its coin-shaped seed pods.
