Exploring the organ-flower-inflorescence boundary. The main uses of spurges are horticultural. The Romans defeated Juba I in 46 BC laurifllia took his son back to Rome, where he was educated and became a learned scholar with interests in natural history.

Five glands with fingerlike appendages Four glands with fingerlike appendages Five glands without appendages.

Succulent euphorbias are most diverse in southern and eastern Africa and Madagascar, but they also occur in tropical Asia and the Americas. Many of the herbaceous, leafy species of Euphorbia are commonly called “spurges. 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 milky sap or latex fuphorbia spurges is suggested to have a protective and defensive role in helping heal wounds and in deterring lauriflia plant-eaters.

Tree-like plant Prostrate herb Candelabriform tree.

Euphorbia laurifolia Juss. ex Lam.

Annual herb Perennial herb Succulent cushion-like plant. Threre are many local names for particular species of Euphorbia.

There are hundreds of cultivars of Poinsettia E. There are potentially three seeds per capsule, and there is a wide variety of size, shape, and surface features of the uephorbia and capsules. Inside the involucre are the flowers, usually with a number of extremely simplified male flowers consisting of a single anther, filament, and pedicel.

Other common names in Euphorbia Threre are many local names for particular species of Euphorbia. What makes a Euphorbia? Red Cyathophylls Red bracteate leaves and cyathophylls Green cyathophylls White bracteate leaves. 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.

Comparative ontogeny of the cyathium in Euphorbia Euphorbiaceae and its allies: Five glands Six glands with petaloid appendages Fused glands, ring-shaped.

Euphorbia laurifolia Juss. ex Lam. — The Plant List

At its euphorbai, in a number of species in the Chamaescyce lineage, the plant will germinate, dichotomously branch, flower, fruit, and die in a matter of weeks. Compounds known as laurufolia 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.

The colorized scanning electron micrograph on the right is reproduced here with permission of the American Journal of Botany. More details about this research can be found in: 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.

All flowers in the Euphorbiaceae are unisexual either male or female onlyand they are often very small euphorbbia size. A large portion of euphorbias, however, are succulent, with thickened, photosynthetic stems and very ephemeral leaves if present at all.

Cyathia are often aggregated into more complex units synflorescencesusually based on an inflorescence model called laurifolix cyme or an umbel.

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. 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.

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. It contains at least 2, species and is one of the most diverse groups of flowering plants on earth.

Some species of Euphorbia have been used in folk medicine over the centuries, especially in the Euphorbia esula alliance. There are many annual or perennial herbs, and these tend to retain leaves through their active growing periods. In other cases, such as E.

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. Actinomorphic cyathium Zygomorphic cyathium Strongly zygomorphic cyathium. Seeds of some species have a fleshy appendage called the caruncle above the point of attachment to the central column of the fruit. 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.

Laurfiolia languages other than English, there are also many common eupuorbia for different species of Euphorbiabut they will be included in individual species pages. The main laurirolia feature of the cyathium is the floral envelope or involucre that surrounds each group of flowers. 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.

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. In Euphorbiathe flowers are eupphorbia even more and then aggregated into an inflorescence or cluster of flowers known as a “cyathium” plural cyathia.
