Key pattern

Alternate simple leaves on shrubs and trees adapted to dry, rocky habitats; flowers show four clawed petals and a ring of many long stamens that project well past the petals on a stalked ovary (gynophore), giving the flower a spidery, exploded look.

Pickled flower buds and immature fruit (capers) come from the same acrid, mustard-oil-bearing tissues found throughout the family — a chemical defence shared with its mustard-family relatives.
