Here we show a small representation of Euphorbia life forms: American Journal of Botany Exploring the organ-flower-inflorescence boundary. Origin of the botanical Latin name Euphorbia.

Tree-like luarifolia Prostrate herb Candelabriform tree. There are many annual or perennial herbs, and these tend to retain leaves through their active growing periods. Some of the variations are described below: In Euphorbiathe flowers are reduced even more and then aggregated into an inflorescence or cluster of flowers known as a “cyathium” plural cyathia.

There are also many herbaceous species that are cultivated, such as Snow on the Mountain E. Threre are many local names for particular species of Euphorbia.

Five glands with fingerlike appendages Four glands with fingerlike appendages Five glands without appendages. Fruits of Euphorbia are capsules that typically split open explosively when ripe. The most current information places Euphorbia species into four distinct monophyletic groups or clades. Seeds of some species have a fleshy appendage called the caruncle above the point of attachment to the central column of the fruit. This feature is present in euphorhia species of the genus but nowhere else in the plant kingdom.

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 euphorbiia genera, such as ChamaesyceMonadeniumPedilanthusand Poinsettia. Cyathia can differ widely in the presence of associated bracts or cyathophylls.

Cyathia are often aggregated into more complex units synflorescencesusually based on an inflorescence model called a cyme or an umbel. Digital art and illustrations: What makes a Euphorbia? Comparative ontogeny of the cyathium in Euphorbia Euphorbiaceae and suphorbia allies: Many succulents are in turn thorny, and some have well developed underground tubers.

Euphorbia obesa is a commonly cultivated globoid and thornless species. Euphorbia cotinifolia and E.

Some species of Euphorbia have been used in folk medicine over the centuries, especially in the Euphorbia esula alliance. Candelilla wax is obtained from E. Inside the involucre are the flowers, usually with a number of extremely simplified male flowers consisting of a single anther, filament, and pedicel.

The variety of habits or life forms is one of the most salient features of Euphorbia. Apparently Juba’s romanization did not sit well with alurifolia 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 — not the same as modern Mauritania, which is located on euphorbka Atlantic coast of Africa south of Western Sahara.

There are also leafy shrubs and trees species that can reach 20 meters high. 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.

Some other names used for different species of Euphorbia include “Snow-on-the-mountian”, “Medusa’s head”, “Mexican fire plant”, and “Scarlet plume”. 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.

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.

From this kind of precursor, the cyathium was presumably formed by a strong condensation of the inflorescence into its current involucres. Juba II also commissioned an expedition to the Canary Islands, where other species of Laurifola were found.

Actinomorphic cyathium Zygomorphic cyathium Strongly zygomorphic cyathium. 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 laurfolia male flowers.

A large portion of euphorbias, however, are succulent, with thickened, photosynthetic stems and very ephemeral leaves if present at all. Five glands Six glands with petaloid appendages Fused glands, ring-shaped. All flowers in the Euphorbiaceae are unisexual either male or female onlyand they are often very small laurifola size.
