The term cipsela, in botany, means the indehiscent dry fruit typical of the Asteraceae family and however present in others such as in the Valerianaceae.
The cipsela originates from a monosperm monosperm ovary unifloro, which wraps the achene proper, often welding to it.
The cipsela is often fitted at the apex with a baby food or a crown of hair or bristles, resulting from the transformation of a rudimentary chalice.
This structure allows the dispersion of the seeds thanks to the action of the wind (anemocora dissemination).
It should also be noted that a layer of phytomelanin is present in the cipsela of some Asteraceae species; this is an acellular organic substance, which adapts to the morphology of the intercellular spaces between the hypodermis and the sclerenchyme of the fruit; this particular condition gives the reproduction structure exceptional resistance to some external agents such as: bacterial decompositions, attacks by insects, in particular from the larvae of the moths of sunflowers (Homoesoma spp.).
