A small population of giants was discovered by a survey team from the Botanical Survey of India in a secluded part of Kalakkad Reserve forest alt. Stems: cm thick, green, glabrous, branching from upper parts; upward curving, segmented. The odour of its latex is pungent and lingering. Ribs: 3 or prominent, winglike, up to cm wide, mm thick, prominently triangular toothed. Spines: Paired, sharp, mm long, spine shields small, stipules pricklelike.

Syn: Euphorbia antiquorum var. Stamens numerous. Capsules nearly1 cm in diameter; cocci compressed, glabrous; style 2 -fid. Succulent shrub, often planted in gardens and rockeries. The woody spiny species of Euphorbia can be separated as under: Stem rounded, not angled or winged I suspect this to be a different species owing to the colour of flowers.
Please help to solve this. Could this be E. Kindly excuse me for mixing two species? Please guide me in this morphology of Euphorbia spp. The previous plant posted have straight grooves and not that of E.
Is this any physical variation or totally the species is different? Attaching the pictures of the one identifed by Dr. Antiquorum L. Just next to it is another species which as Sir said goes as E. Attaching that too for comparison. Hope this helps! Lectotype : Herb. Commelins : 97 You can clearly make out which is the real Euphorbia antiquorum. There is another species called Euphorbia royleana.
Kindly check your plant with that description. I am not sure if this plant is found in South India but it is supposed to be widespread from Pakistan to Taiwan. I assume I have seen it in Uttarakhand as well as Rajasthan.
Euphorbia is a very big group and one most interesting thing is, the genus Euphorbia has two type species, Euphorbia antiquorum and Euphirbia serrata. I never heard a genus with two types before. If anyone else knows then please do add to our information. That itself depicts the taxonomic complications here. It is without any wings and with spines which are spirally arranged.
It should be E. I totally forgot about neriifolia. If you look at the second group of pics shared by Secondly, in the lectotype, the wings are not straight. I have seen both of these plants myself in gardens, and I always thought one of them to be hybrid. But you are more experienced so you must be having a better idea. If you look carefully the type specimen cited by you also has straight wings. I understood what you meant.
I just imagine if those contractions and swelling are due to environmental factors or that is a consistent character of this taxa? Undoubtedly Euphorbias are complicated!! However the plant does not matches with E. What I had posted are young and old plants of the same species. But there are some taxa in Euphorbia and others too, in which such characters are genotypic.
Hope you understand my point there. Yes the plant was not E. As I said before, I completely forgot about E. Euphorbia is very complicated, jut put together Euphorbia thymifolia and Euphorbia cotinifolia and without flowers and latex, you dont find anything common!!

Learn how and when to remove this template message Like all members of the family Euphorbiaceae, spurges have unisexual flowers. In Euphorbia, flowers occur in a head, called the cyathium plural cyathia. Each male or female flower in the cyathium head has only its essential sexual part, in males the stamen , and in females the pistil. The flowers do not have sepals , petals , or nectar to attract pollinators, although other nonflower parts of the plant have an appearance and nectar glands with similar roles. Euphorbias are the only plants known to have this kind of flower head.

A significant number are succulent, all contain latex and have a unique flower structure. Although it is present in many traditional medicinal systems, nearly all possess poison or toxicity. Botany Euphorbia antiquorum is a succulent woody shrub growing 1 to 3 meters high with milky sap. Mature stem is cylindrical in shape with 3 to 6 ridges; younger branches green with 3 to 5 ridges; the projection of the ridges are armed with a pair of 2- to 3-millimeter long spines. Leaves are few, borne on the ridges, succulent, obovate to oblanceolate to spathulate in shape. Apex is obtuse with a small pointed projection, base gradually narrowing downward, sessile.
