Comparative ontogeny of the cyathium in Euphorbia Euphorbiaceae and its allies: Medusoid succulent herb Shrub with pencil-like branches Sphaeroid succulent plant. Generally there is a single female flower in the center consisting of a pedicel, a three-parted ovary, and no petals or sepals associated laurifoolia it.

The implications of this finding for understanding the evolution of Euphorbia are significant, and further understanding the phylogenetic relationships within subgenus Esula may help us understand where and how laurifooia genus evolved and spread to its current worldwide distribution.

For languages other than English, there are also many common names for different species of Euphorbiabut they will be included in individual species pages.

Gerhard Prenner and Paula Rudall at the Royal Botanic Gardens, Kew England are currently studying the origin of the cyathium euphornia comparing its early stages of development using scanning electron micrography and comparing them to the closest relatives of Euphorbia. The name, however, goes much farther back in history, and we can trace its origin at least as far back as the Roman officer Pliny the Elder, who named Euphorbia in his book, the Natural History of Pliny 79 AD.


A large portion of euphorbias, however, are succulent, with thickened, photosynthetic stems and very ephemeral leaves if present at all. Here we show a small representation of Euphorbia life forms: Since euphorbus also means “good fodder” or well-fed in Greek, there is also some speculation that Juba coined the name because both the plant and his physician were of rather fleshy constitution.

This feature is present in every species of the genus but nowhere else in the plant kingdom.

Candelilla wax is obtained from E. With this basic model of the cyathium, many modifications upon it have evolved in the genus, as well as in the aggregation of cyathia into higher order units.

Euphorbia laurifolia Lam.

About the genus Euphorbia. Seeds of some species have a fleshy appendage called the caruncle above the point of attachment to the central column of the fruit. Some other names larifolia for different species of Euphorbia include “Snow-on-the-mountian”, “Medusa’s head”, “Mexican fire plant”, and “Scarlet plume”.

Juba II also commissioned an expedition to the Canary Islands, where other species of Euphorbia were found. There are hundreds of cultivars of Poinsettia E.

Euphorbia laurifolia Juss. ex Lam.

Inside the involucre are the flowers, usually with a number of extremely simplified male flowers consisting of a single anther, filament, and pedicel. Succulent euphorbias are most diverse in southern and eastern Africa and Madagascar, but they also occur in tropical Asia and the Americas. What lauriflia a Euphorbia?

Fruits of Euphorbia are capsules that typically split open explosively when ripe. Euphorbia is a genus of plants in the Euphorbiaceae family.

Other common names laurufolia Euphorbia Threre are many local names for particular species of Euphorbia. Whereas most other large genera of plants differ in features of the flowers themselves, Euphorbia varies instead in features of the cyathium, which can show amazing modifications in different groups within the genus.

Tropicos | Name – Euphorbia laurifolia Juss. ex Lam.

It contains at least 2, species and is one of the most diverse groups of flowering plants on earth. Some of the variations are described below: Cyathia are often aggregated into more complex units synflorescencesusually based on an inflorescence model called a cyme or an umbel.

There are many herbaceous spurges, especially in temperate zones worldwide, but the genus is best known for its many succulent species, some of which appear very similar to cacti.

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 following relationships among the four main clades of Euphorbia: Compounds known as terpene esters are common and often account for the extremely caustic and irritating properties of the milky sap, either by direct contact with the skin or even by exposure to the air and inflammation of the eyes or mucous membranes.

At its simplest, in a number of species in the Chamaescyce lineage, the plant will germinate, dichotomously branch, flower, fruit, and die in a matter of weeks. In other cases, such as E. Five glands Six glands with petaloid appendages Fused glands, ring-shaped.
