Genus: Euphorbia
The spurges make up Euphorbia, a very diverse genus of plants, belonging to the spurge family (Euphorbiaceae). Consisting of about 2160 species, spurges are one of the largest genera in the plant kingdom. The genus is primarily found in the tropical and subtropical regions of Africa and the Americas, but also in temperate zones worldwide. Succulent species originate mostly from Africa, the Americas and Madagascar. There exists a wide range of insular species, namely on the Hawaiian Islands where spurges are collectively known as ʻakoko[verification needed]
The common name "spurge" derives from the Middle English/Old French espurge ("to purge"), due to the use of the plants sap as a purgative.
The botanical name Euphorbia derives from Euphorbus, the Greek physician of king Juba II of Numidia (52-50 BC - 23 AD). He is reported to have used a certain plant, possibly Resin Spurge (E. resinifera), as a herbal remedy when the king suffered from a swollen belly[verification needed]. Carolus Linnaeus assigned the name Euphorbia to the entire genus in the physician's honor.
Juba II himself was a noted patron of the arts and sciences and sponsored several expeditions and biological research. He also was a notable author, writing several scholarly and popular scientific works such as treatises on natural history or a best-selling traveller's guide to Arabia. Euphorbia regisjubae (King Juba's Euphorbia) was named to honor the king's contributions to natural history and his role in bringing the genus to notice.The plants are annual or perennial herbs, woody shrubs or trees with a caustic, poisonous milky sap (latex). The roots are fine or thick and fleshy or tuberous. Many species are more or less succulent, thorny or unarmed. The main stem and mostly also the side arms of the succulent species are thick and fleshy, 15-91 cm (6-36 inches) tall. The deciduous leaves are opposite, alternate or in whorls. In succulent species the leaves are mostly small and short-lived. The stipules are mostly small, partly transformed into spines or glands, or missing.
Like all members of the family Euphorbiaceae, all spurges have unisexual flowers. In Euphorbia these are greatly reduced and grouped into cyathia called pseudanthia. There are also (monoecious) species with male and female flowers on the same plant and those (dioecious) with male and female flowers occurring on different plants. It is not unusual for the central cyathia of a cyme to be purely male, and for lateral cyathia to carry both sexes. Sometimes young plants or those growing under unfavourable conditions are male only, and only produce female flowers in the cyathia with maturity or as growing conditions improve. The bracts are often leaf-like, sometimes brightly coloured and attractive, sometimes reduced to tiny scales. The fruits are three (rarely two) compartment capsules, sometimes fleshy but almost always ripening to a woody container that then splits open (explosively). The seeds are 4-angled, oval or spherical, and in some species have a caruncle.

Il genere Euphorbia comprende un vasto numero di piante dicotiledoni della famiglia delle Euphorbiaceae, erbacee o legnose a seconda della specie.
Il termine Euphorbia deriverebbe dal nome del medico greco Euphorbus, che utilizzava il succo lattiginoso prodotto da queste piante nelle sue pozioni. Era il medico personale di Giuba II e fu questo dotto sovrano a denominare così in suo onore la pianta, all'interno di un trattato che scrisse per illustrarne le virtù terapeutiche.Il genere varia da piccoli alberi, arbusti, viti a piante erbacee. Una percentuale significativa di queste sono piante succulente, alcune delle quali assomigliano straordinariamente ai cacti nonostante non siano apparentate, un esempio di evoluzione convergente. Ad eccezione di poche specie (es: Euphorbia hedytoides o Euphorbia curtisii), questo genere è composto da specie ermafrodite.
Le euphorbie hanno una infiorescenza altamente specializzata: il ciazio, che sono fiori unisessuali ridotti, raggruppati in una caratteristica pseudanthia. Consiste in un fiore centrale pistillato circondato da cinque gruppi di fiori staminati. Tutti i fiori sono inclusi in un involucro con quattro ghiandole marginali. Il fiore centrale si sviluppa prima dei fiori maschili che lo circondano, così ogni ciazio funziona come un fiore ermafrodito protogynous. La ghiandole del ciazio generalmente producono nettare, e l'impollinazione è prevalentemente zoofila. In effetti, il ciazio è così simile ad un fiore ermafrodita che Linneo e altri autori lo indicavano come un vero fiore. Lamarck tuttavia interpretò il ciazio come una infiorescenza e questo è quanto oggi accettato.
Le euphorbie contengono un lattice acre e velenoso, ed alcune sono dotate di spine. Da molte euphorbie si ricavano potenti prodotti emetici e catartici. genere è diffuso principalmente nelle regioni tropicali dell'Africa e dell'America, ma anche nelle zone dal clima temperato. Le specie succulente sono originarie principalmente dell'Africa e del Madagascar.

and and artistic close up, TFS Ori

First of all, thanks for the insight into Spurges through your good note, Luciano.
In this picture, you have again handled your settings deftly to give us a brilliant and almost three-dimensional image of this well-shaped flower.
The colours too are very delicate and charming.
TFS and best regards.

Hi Luciano,
Excellent shot and the formation looks so artistic. Superb soft green colours and sharp details. Looks so pleasant to the eyes and you have skilfully chosen a top POV to portray them. Great DOF isolates it from the BG perfectly. Very nicely composed. Kudos.
TFS.

Euphorbias are amazing plants and your shot is equally fantastic in colors, sharpness and details. Very beautiful close POV.

Hi Luciano,
A nice capture of this beautiful flower. Excellent sharp details and a fine composition. Thanks a lot for sharing.

Interesante y fresca, es la que toca por la época. Una planta que atrae muchos insectos en estos días y muy valorado por ello por fotógrafos como yo jajaja.
En lo técnico no es muy linda :-( ya que hay un exceso de ruido electrónico y los colores algo "quemados" pero bueno, la próxima mejor.

Hi Luciano!

Wonderful shot well lit, and fantasticly composed, with that little worm on it especially! I like the top view and small dof. Chilling tone of green and wonderful details, TFS!

Best regards,
Andor

mi hanno sempre incuriosito le euforbie con il loro latet cattivissimo (appiccia da paura.) bella cattura di una infiorescenza complessa
ciascun fiore sembra ub utero gravido (scusami - deformazione professionale) ma acostati formano un cuore.. verde speranza e allegro primavera...
bravo maestro

Lovely close-up, Luciano!

We have 40 species of Euphorbia, but not this one.

Cheers!
