With more than 32,000 species, the Asteraceae is arguably the largest of plant families (although closely rivalled by the Orchidaceae); it includes many flowers of similar appearance - densely packed heads comprising numerous tiny flowers or florets (hence the old family name Compositae meaning 'composed of many little flowers'). The internal florets are symmetrical with tiny petals, while each of those at the edge - the so-called 'ray florets' - have mostly tiny petals but one large petal facing outwards. The name Asteraceae refers to the star-like form of the inflorescences.
