|[Note Guidelines] Photographer's Note|
|This beautiful and special looking flower was found on the slopes on Mt. Vesuvius|
What attracted me the most is the symmetrical shape and details of the flowers.
I assume is one of the 2160(!) species of the Euphorbia genus.
Note - thanks Maite and Ori for the ID - Euphorbia helioscopica
Purges (Euphorbia) are a very diverse worldwide genus of plants, belonging to the spurge family or Euphorbiaceae. Consisting of about 2160 species spurges are one of the largest genera in plant kingdom.
The latex (milky sap) of spurges acts as a deterrent for herbivores as well as a wound healer. Usually it is white, but in rare cases (e.g. E. abdelkuri ) yellow. As it is under pressure, it runs out from the slightest wound and congeals within a few minutes of contact with the air. Among the component parts are many di- or tri-terpen esters, which can vary in composition according to species and in some cases the variant may be typical of that species. The terpen ester composition determines if the latex is slightly or very caustic and irritating to the skin, and especially if in contact with mucous membranes (eyes, nose, mouth) can produce extremely painful inflammation. In experiments with animals it was found that the terpen ester resiniferatoxin had an irritating effect 10,000 to 100,000 times stronger than capsaicin, the "hot" substance found in chillies. Several terpen esters are also known to be carcinogenic.
Therefore handling spurges needs to be done with caution. Latex coming in contact with the skin should be washed off immediately and thoroughly. Partially or completely congealed latex is often no longer soluble in water, but can be removed with an emulsion (milk, hand-cream). With inflammation of a mucous membrane a doctor needs to be consulted. If cutting large succulent spurges in a greenhouse, it has been noticed that vapours from the latex spread and can cause severe irritation to the eyes and air passages several metres away. Caution is therefore required and for example ensure sufficient ventilation. Small children and domestic pets should never come into contact with spurges.
