Yes … I have seen this plant on Mahabaleshwar too.


Thanks …, In that case, if my understanding goes right, it is species of high altitude grasslands.

BSI Flora of Maharashtra and FOS mentions this as Euphorbia laeta.
Family : Euphorbiaceae.
Syn. Euphorbia rothiana


True … Until BSI flora is referred in its book form, such differences will be observed. Hopefully, a website would come up soon.
Shrikant ji’s new edition of FOS reflects E. rothiana, though E. laeta seems to have inadvertently got retained in Flowers of Kas.
Made changes in my flickr notes during the routine of uploads.


Euphorbia laeta B Heyne ex Roth. (1821) can’t be the correct name for two reasons

1. It is an illegitimate name being a later homonym of E. laeta Aiton (1789), a totally different species now considered as synonym of Euphorbia dendroides L.
This is another example of confusions we land into when not citing the authors. I found numerous entries on the web of this plant, with two as synonyms and none citing the authority.
E. rothiana Spreng should thus be taken as correct name and Euphorbia laeta B. Heyne ex Roth as synonym.


Interesting discussion…
1: is this native of the mediterranean islands? since the website link is from univ in the tiny island…
2: the pictures of their garden’s samples seem several years old…
do they grow that big in KAS or in the western ghats… ie comfortable for a few years?
or do they get eaten by goats etc and are seen small specimen only?
or are they newly naturalized “weeds” ???


Responding to the query: (1) is this native of the mediterranean islands?
No. This is native of peninsular India and Sri Lanka.


I think you got confused. E. dendroides is a different species not found in India. It shares with E. rothiana of Kas region, the synonyms which are homonyms.


NO I AM NOT CONFUSED
I was looking at the plants in the link you gave above .. its from a university on the Mediterranean islands off coast of Spain
my question was about this E. laeta… that website shows plants older than any I have seen from any indian book or site…hence the questions…
if it is our native.. how come we / indians dont have pictures of older plants ????
that’s what I as asking… or are the spaniards more careful of their plants?  


There are two different plants:
E. laeta Heynes ex Roth (1821)
E. laeta Aiton (1789)
Since two different species are given the same name they are homonyms, former being later homonym (junior homonym) is rejected irrespective of whether E. laeta Aiton (earlier homonym or senior homonym) is accepted name or not. E. laeta Aiton happens to be a synonym of E. dendroides L., a fact that has come to light relatively recently and this old website does not give this synonym. My purpose of the link was only to show how different this plant looks. And it does not grow in India.
The Indian plant was described in Flora of British India as E. rothiana Spreng with E. laeta Heynes ex Roth as synonym. Since latter has earlier date of publication, so several recent books treated E. laeta Heynes ex Roth as correct name and E. rothiana a synonym, but the decision had to be reversed once it was known that it is a later homonym.

Euphorbia dracunculoides?? from Kas

I hope it is E. rothiana
