[ushadi]

you are welcome

I have grown these in various continents

always in tubs

and after a while thy must go into the garden soil

they don't like to be in pots for ever.

one died when I trusted my plants to a gardener

who killed it with kindness

overwatering kills it

Dear Garg Ji

This is a cultivated species, not indigenous to the Indian subcontinent.  I am not able to name it.

With regards

Hi, Balakrishnan ji,

Can it be Euphorbia trigona as suggested by Ushadi and as identified by you at Euphorbia trigona Mill (?) from Assam ?

[J.M. Garg]

Thanks, Balakrishnan ji

Dear All

Yes. It appears to be Euphorbia trigona

 Dear Garg ji,

Yes, you have pointed to the possibly correct identity. The only difference from E. trigona Miller is that the space between the wings is not marked by white patches. When the plants are in flower, it can be confirmed.

This species is of African origin and is called  African Milk Tree, and is found in Andhra Pradesh, Karnataka, Tamil Nadu and Andaman & Nicobar Islands.

OK kids, fasten your seatbelts, this quick and dirty summary is coming to you courtesy of Daryl Koutnik's article in the Euphorbia journal Volume 7 (published in 1991). All the mistakes are mine. Go find yourself a copy of the original to see all the gory details. E. trigona was originally described in 1768 by Miller, who said the plant was from Sri Lanka (then Ceylon?). It has never been found there except in cultivation. It was also described later in 1812 by Haworth (who properly credited Miller, but has received credit mistakenly by various publications). Also, there was for some time another species called E. barnhartii, which was named by Lemaire 90 years after trigona, then subsumed into trigona, then moved elsewhere. The thrust of the article (other than telling an interesting historical story) is whether trigona can be distinguished from hermentiana, and honestly I don't even want to go there. So we'll skip that angle. Suffice to say the CoL has placed that plant under trigona, and barnhartii under lacei, so that's their state of the art, such as it is today. After the original description of E. trigona, subsequent authors (like Haworth) described it as from India, and you will see other references to that as well, but apparently there is no actual wild trigona growing there, just cultivated plants gone feral and similar-looking plants being misidentified. So that geotag has been formally debunked as well. The earliest description of E. trigona (in the 17th century) came before it had a proper name, and that reference mentions material from West Africa, so we now have a third potential site of origin which has not been well confirmed (at least not in 1991). To quote the author regarding identification of Euphorbia trigona in its various forms: "the key similarity in all of the descriptions is that the branches are not spreading but erect (appressed)". And regarding the flowers, the plant only flowers in tropical climates and has only been recorded to flower twice in history (though Haworth does mention flowers, he does not describe them). Again, this info is from 1991, but from a source I respect. I think it's pretty clear this plant has a history like Aloe vera, in being selected and cultivated far and wide long after the wild plants disappeared from habitat. As Daisy says, some plants cannot produce seed after being grown by humans from cuttings for so long (Aloe vera), even though they flower. Apparently Euphorbia trigona doesn't even get that far except by freak random chance.
