- Structure of a typical flower; bracteate and ebracteate; symmetry (actinomorphic, zygomorphic); merous condition; complete and incomplete flowers
- Non-essential whorls: calyx and corolla (gamo- and poly- forms), perianth; aestivation (valvate, twisted, imbricate, vexillary)
- Androecium: cohesion (syngenesious, synandrous, mon-, di- and polyadelphous), adhesion (epipetalous, epiphyllous), monothecous and dithecous anthers
- Gynoecium: position of ovary (hypogynous, perigynous, epigynous); apocarpous and syncarpous; locules; placentation (axile, marginal, parietal, free central, basal)
- Inflorescence: racemose and cymose - definitions, examples and differences
