Actinomorphic cyathium Zygomorphic cyathium Strongly zygomorphic cyathium. All flowers in the Euphorbiaceae are unisexual either male or female onlyand they are often very small in size. Many of the herbaceous, leafy species of Euphorbia are commonly called “spurges. There are also many herbaceous species that are cultivated, such as Snow on the Mountain E. Gerhard Prenner and Paula Rudall at the Royal Botanic Gardens, Kew England are currently studying the origin of the cyathium by comparing its early stages of development using scanning electron micrography and comparing them to the closest relatives of Euphorbia.

Red Cyathophylls Red bracteate leaves and cyathophylls Green cyathophylls White bracteate leaves. Fruits of Euphorbia are capsules that typically split open explosively when ripe.

Here we show a small representation of Euphorbia life forms: Recent work by Kenneth Wurdack and Benjamin Van Ee has examined 15 different regions from the three plant genomes nuclear, chloroplast, and mitochondrialand this now shows clear support for the laugifolia relationships among the four main clades of Euphorbia: Comparative ontogeny of the cyathium in Euphorbia Euphorbiaceae and its allies: They track the origin of Euphorbia to relatives from the Old World Australia, New Caledonia, Africa, and Madagascar and conclude that the cyathium evolved from a more open grouping of flowers called a thyrse, with a terminal female flower surrounded by cymes of male flowers.

Origin of the botanical Latin name Euphorbia.

The milky sap or latex of spurges is suggested to have a protective and defensive role in helping heal wounds and in deterring potential plant-eaters.

Euphorbia became the official botanical name for the genus when Carolus Linnaeus published it in the first edition of his book Species Plantarum, in p. There are potentially three seeds per capsule, and there is a wide variety of size, shape, and surface features of the seeds and capsules.

The involucre almost always has one or more special glands attached to it, most often on the upper rim, and these glands and their appendages vary greatly in size and shape.

The variety of habits or life forms is one of the most salient features of Euphorbia. This feature is present in every species of the genus but nowhere else in the plant kingdom. From this kind of precursor, the cyathium was presumably formed by a strong condensation of the fuphorbia into its current involucres.

The Romans defeated Juba I in 46 BC and took his son back to Rome, where he was educated and became a learned scholar with interests in natural history. Medusoid succulent herb Shrub with pencil-like branches Sphaeroid succulent plant.
