In addition to noting the kind of inflorescence, examine and de- scribe the bracts (small leaves), pedicels, and larger branches of the flower cluster, noting their shape, size, surface, and color. FLORAL SYMMETRY. Floral WhorlsâThe parts of the flower are mostly arranged in whorls or cycles, distinctly separated from each other {cyclic flowers); in some cases they are arranged in spirals, with, however, a distinct separation of the different groups of organs {hemicyclic flowers); in still other cases the arrangement is spiral through- out, with no separation of the groups of organs (acyclic flowers). In cyclic flowers there are most frequently four or five whorls, viz.
