A cyathium plural cyathia is one of the specialised Pseudanthium pseudanthia false flowers forming the inflorescence of plants in the genus Euphorbia Euphorbiaceae . A cyathium consists of Five rarely four bracteoles. These are small, united bract s, which form a cup like involucre. Their upper tips are free and in the beginning cover the opening of the involucre like the shutter of a camera . These alternate with Five 1 to 10 nectar gland s, which are sometimes fused. One extremely reduced female flower standing in the centre at the base of the involucre, consisting of an ovary plants ovary on a short stem with pistil , and surrounded by Five groups one group at the base of each bracteole of extremely reduced male flowers, which each consist of a single anther on a stem. The flower like characteristics of the cyathia are underlined by brightly coloured nectar glands and often by petal like appendages to the nectar glands, or brightly coloured, petal like bracts positioned under the cyathia. The paired petal like bracts in the sub family Euphorbia section Goniostema are called cyathophylls . The cyathia are sometimes solitary, but are usually in Cyme botany cymes , inflorescences of the second order, in pseudumbels, on dichotomously branched stalks or in so called simple cymes which consist of one central and two lateral cyathia. In one group of Madagascan species in the sub family Euphorbia section Goniostema E. aueoviridiflora , E. capmanambatoensis , E. iharanae , E. leuconeura , E. neohumbertii , E. viguieri there is a tendency for a further pseudanthium to grow from the cyme.

Image E obesa obesa ies.jpg thumb left Male flowers Image Euphorbia obesa obesa3 ies.jpg thumb left Female flowers The plant is dioecious which means that a subject has only male or female flowers. In the wild, it is endangered because over collection and poaching, because of its slow growth, and the fact that the pod contains only 2 to 3 seeds. However, it is widely cultivated in botanical gardens. Description Euphorbia obesa looks like a perfect ball, thornless and extremely decorative. Its diameter is 6 cm for young subjects, but can reach 15 cm for the old ones. Its shape is spherical for young individuals and cylindrical for the old ones. It contains a water reservoir for periods of drought.

In fact, like all Euphorbia , flowers are called cyathium cyathia . Like all Euphorbia , the latex sap is toxic.
