The Calyceraceae are a family in the order of the aster -like ( Asterales ). In this family, there are four to six genera and about 40 species with purely neotropical distribution; all kinds have their areas in South America. Most species grow in the Andes.

Description

Types of Calyceraceae are annual or perennial herbaceous plants. The change-constant leaves are simple or pinnate. In some species the leaves are in basal rosettes. The leaf margins are all about. Stipules absent.

There are both taxa with hermaphrodite and taxa with unisexual flowers; male and female flowers are on one plant, so they are monoecious getrenntgeschlechtig ( monoecious ). The flowers are borne ( inflorescences ), individually or in mostly capitate or rarely racemose inflorescences. The small flowers are usually fünfzählig (rarely four or sechszählig ) and radial symmetry to slightly zygomorphic. The two Blütenhüllblattkreise are distinctly different. The sepals in all kinds of ways in thorns. The petals are fused into a tube. There is only one district with mostly five (rarely four or six) free fertile stamens. The stamens are fused to the upper part of the corolla tube. Sometimes only one carpel is present, usually two carpels are fused into one inferior ovary. It is a pen and a scar present. Pollination is by insects ( entomophily ). Are formed achänenähnliche fruits, they are crowned by the remains of calyx and corolla.
