Fruits of Euphorbia are capsules that laurigolia split open explosively when ripe. The main defining feature of the cyathium is the floral envelope or involucre that surrounds each group of flowers.

Euphorbia laurifolia Juss. ex Lam.

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. Here we show a small representation of Euphorbia life forms: Fused glands, u-shaped Single gland Single gland.

American Journal of Botany One of the Canary species was eventually named Euphorbia regis-jubae in his honor.

Cyathia can differ widely in the presence of associated bracts or cyathophylls. The main uses of spurges are horticultural. Many of the species are known as “spurges. 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. Digital art and illustrations: Juba II also commissioned an expedition to the Canary Islands, where other species of Euphorbia were found.

Laurfolia euphorbias are most diverse in southern and eastern Africa and Madagascar, but they also occur in tropical Asia and the Americas.

Euphorbia laurifolia Lam.

For languages other than English, there are also many common names for different species of Euphorbiabut they will be included in individual species pages. In Euphorbiathe flowers are reduced even more and then aggregated into an inflorescence or cluster of flowers known as a “cyathium” plural cyathia. 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.

Recent work by Kenneth Wurdack and Benjamin Van Ee has examined 15 different regions from the laurifokia plant genomes nuclear, chloroplast, and mitochondrialand this now shows clear support for the following relationships among the four main clades of Euphorbia: Some of the variations are described below: Apparently Juba’s romanization did not sit well with the laurlfolia 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 — not the same as modern Mauritania, which is located on the Atlantic coast of Africa south of Western Sahara.

There may be specialized leaves called cyathophylls or cyathial leaves that surround the cyathium and give an overall flower-like appearance to the whole complex inflorescence. Many succulents are in turn thorny, and some have well developed underground tubers.

In other cases, such as E. 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. Medusoid succulent herb Shrub with pencil-like branches Sphaeroid succulent plant. Among the succulent or thorny species, E. 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.

Tree-like plant Prostrate herb Candelabriform tree. A large portion of euphorbias, however, are succulent, with thickened, photosynthetic stems and very ephemeral leaves if present at all. In terms of symmetry, cyathia can be essentially actinomorphic, with many planes of symmetry, or slightly or strongly zygomorphic bilaterally symmetrical, with only one plane of symmetry.

Euphorbia is a genus of plants in the Euphorbiaceae family. Actinomorphic cyathium Zygomorphic cyathium Strongly zygomorphic cyathium. There are potentially three seeds per capsule, and there is a wide variety of size, shape, and laurifilia features of the seeds and capsules.

Other common names in Euphorbia Threre are many local names for particular species of Euphorbia.

Comparative ontogeny of the cyathium in Euphorbia Euphorbiaceae and its allies: The colorized scanning electron micrograph on the right is reproduced here with permission of the American Journal of Botany. There are also many herbaceous species that are cultivated, such as Snow on the Mountain E.

Five glands with fingerlike appendages Four glands with fingerlike appendages Five glands without appendages. Some other names used for different species of Euphorbia include “Snow-on-the-mountian”, “Medusa’s head”, “Mexican fire plant”, and “Scarlet plume”.

The number and forms of involucral glands as laurkfolia as gland appendages varies enormously as shown by these examples below.

Euphorbia laurifolia Juss. ex Lam. — The Plant List

With this basic model of the cyathium, many modifications upon it have evolved in the genus, as well as in the aggregation of cyathia euphorbiw higher order units. Origin of the botanical Latin name Euphorbia. About the genus Euphorbia. This feature is present in every species of the genus but nowhere else in the plant kingdom.

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.

Many of the herbaceous, leafy species of Euphorbia are commonly called “spurges. According to Pliny, after Juba moved to Mauretania, he was treated with a plant with powerful medicinal euphofbia, and euphoorbia named the plant after his Greek physician Euphorbus.

Cyathia are laurifoli aggregated into more complex units synflorescencesusually based on an inflorescence model called a cyme or an umbel. Seeds of some species have a fleshy appendage called the caruncle above the point of attachment to the central column of the fruit.

There is a euhporbia variety of chemical compounds present in Euphorbia sap, and some of them are toxic and potentially carcinogenic. There are hundreds of cultivars of Poinsettia E. The Pencil tree of Milk bush E. Euphorbia tithymaloides is an American native that is widely grown in warm climates worldwide. From this kind of precursor, the cyathium was presumably formed by a strong condensation of the inflorescence into its current involucres.
