Each male or female flower in the cyathium head has only its essential sexual part, in males the stamen, and in females the pistil.

It has a unique kind of pseudanthium, called a cyathium, where each flower in the head is reduced to its barest essential part needed for sexual reproduction.

Identification was made using George Dukes "'Mississippi Wildflowers " and the USDA's plant database . " Euphorbia corollata " is an example of a cyathium.
14.
"Euphorbia " flowers are tiny, and the variation attracting different pollinators ( and the human eye ), with different forms and colors occurs, in the cyathium, involucre, cyathophyll, or additional parts such as glands that attached to these.
15.
Nectar glands and nectar that attract pollinators are held in the involucre, a cuplike part below and supporting the cyathium head . ( The " involucre " in the " Euphorbia " genus is not to be confused with the " involucre " in Asteraceae family members, which is a collection of bracts called ( phyllaries ), which surround and encase the unopened flower head, then support the receptacle under it after the flower head opens .)
