means A genus of flowering plants, often potted and fragrant-leaved, that gets casually called 'geranium' even though true geraniums are a different (if related) genus entirely.

from From the Greek 'pelargos,' meaning stork — the seed capsule of these plants is long and tapered, like a stork's bill, which also explains the common nickname 'storksbill.' The confusion with geranium runs deep: that name comes from the Greek 'geranos,' meaning crane, because true geranium seed pods look like a crane's bill. Both plants were lumped together as one genus until the 18th century, when botanists split them apart — pelargonium got its own name, but the old habit of calling it geranium stuck in gardens and garden centers ever since.
