A plant with seeds in a pod shaped like a crane's bill, or the pelargonium flower commonly called geranium.
From Old English 'crane' (the bird) and 'bill' (beak), named descriptively after the shape of its seed pod. The resemblance to a crane's long bill is so obvious that multiple languages used this same metaphor.
The crane's bill shape actually helps the plant scatter seeds—when dry, the pod twists and flings seeds away from the plant, using geometry as a catapult. Humans noticed this mechanism thousands of years ago and named the whole plant after it!
