Asteraceae

Asteraceae () is a large family of flowering plants that consists of over 32,000 known species in over 1,900 genera within the order Asterales. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the number of extant species in each family is unknown. The Asteraceae were first described in the year 1740 and given the original name Compositae. The family is commonly known as the aster, daisy, composite, or sunflower family.

Phytomelanin is found in most families of the Asparagales (although not in Orchidaceae). It is mechanically hard and forms a resistant substance, although it is more pliable in the developing fruit, hardening later. Chemically it appears to be a polyvinyl aromatic alcohol, and is thought to be exuded from the hypodermis. It appears
