American Journal of Botany Tree-like plant Prostrate herb Candelabriform tree. One of the Canary species was eventually named Euphorbia regis-jubae in his honor. There are potentially three seeds per capsule, and there is a wide variety of size, shape, and surface features of euhporbia seeds and capsules.

Red Cyathophylls Red bracteate leaves and cyathophylls Green cyathophylls White bracteate leaves.

The number and forms of involucral glands as well as gland appendages varies enormously as shown by these examples below. More details about this research can be found in: 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.

Five glands Six glands laurofolia petaloid appendages Fused glands, ring-shaped. The variety of habits or life forms is one of the most salient features of Euphorbia. 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.

Cyathia are often aggregated into more complex units synflorescencesusually based on an inflorescence model called a cyme or an umbel. Fruits of Euphorbia are capsules that typically split open explosively when ripe.

What makes a Euphorbia Origin of the cyathium Fruits and seeds Diversity of life forms Uses and eupjorbia Systematics and classification The botanical name Euphorbia Common names. Euphorbia is a genus of plants in the Euphorbiaceae family. Inside the involucre are the flowers, usually with a number of extremely simplified male flowers consisting of a single anther, filament, and pedicel.


Euphorbia cotinifolia and E. Fused glands, u-shaped Single gland Single gland. For languages other than English, there are also many common names for different species of Euphorbiabut they will be included in individual species pages.

Our understanding of the relationships of Euphorbia has been bolstered by comparative DNA sequence data from many species, and these results support a broad view of the genus that includes a number of groups that were formerly recognized as different genera, such as ChamaesyceMonadeniumPedilanthusand Poinsettia.

There is a wide variety of chemical compounds present in Euphorbia sap, and some of them are toxic and potentially carcinogenic. In other cases, such as E.

At euphobria 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. 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 the genus evolved and spread to its current worldwide distribution.

Many of the herbaceous, leafy species of Euphorbia are commonly called “spurges. From this kind of precursor, the cyathium was lauritolia formed by a strong condensation of the inflorescence into its current involucres. What makes a Euphorbia? In Eupjorbiathe flowers are reduced even more and then aggregated into an inflorescence or cluster of flowers known as a “cyathium” plural cyathia. 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.

About the genus Euphorbia. The Pencil tree of Milk lauricolia E. Seeds of some species have a fleshy appendage called the caruncle above the point of attachment to the central column of the fruit. There are also leafy shrubs and trees species that can reach 20 meters high. Many succulents are in turn thorny, and some have well developed underground tubers.

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.

According to Pliny, after Juba moved to Mauretania, he was treated with a plant with powerful medicinal properties, and he named the plant after his Greek physician Euphorbus. There euphoriba hundreds of cultivars of Poinsettia E.

Tropicos | Name – Euphorbia laurifolia Juss. ex Lam.

There are also many herbaceous species that are cultivated, such as Snow on the Mountain E. It contains at least 2, species and is one of the most diverse groups of flowering plants on earth. Apparently Juba’s romanization did not sit well with the local population, and after a few years in Numidia, Augustus transferred him to become King of Mauretania a Berber kingdom that was part of present-day western Algeria and northern Morocco — euphorbja the same as modern Mauritania, which is located on the Atlantic coast of Africa south of Western Sahara.

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. Exploring the organ-flower-inflorescence boundary. Generally there is a single female flower in the center consisting of a pedicel, a three-parted ovary, and no petals or sepals associated with it.
