Modeling Meristic Characters of Asteracean Flowerheads

Johannes Battjes and Przemyslaw Prusinkiewicz

According to Weyl (1952), the word symmetry commonly has two different meanĀ­ings. In one sense, symmetry is defined as a group of transformations that map an object into itself. This usage is reflected in expressions such as bilateral or rotational symmetry. In a broader sense, "symmetric means something like well-proportioned, well-balanced, and symmetry denotes that sort of concordance of several parts by which they integrate into a whole. Beauty is bound with symmetry" (Weyl, 1952). We will use the word symmetry in this broader sense.
