EUPHORBIACEAE FORTNIGHT:: Euphorbia wallichi for validation from Chakrata NS-45 : Attachments (6). 4 posts by 3 authors.
This looks similar to my last post, still posting separately to avoid any confusion..
This Euphorbia was very common in Chakrata area…
Is this also Euphorbia wallichii ??

Fruits are warty, it may be E. pilosa (as number of rays are lesser, in E. cognata (leaves entire, fruits sparingly warty) and E. cornigera (leaves serrulate) rays are usually man
… may give better identification.


If this plant is with unbranched or sparingly branched main stem, then this seems to be Euphorbia cornigera Boiss. var. cognata (Klotzsch) Binojk. & N.P.Balakr. In this variety the tuberles on ovary and fruits are fewer than in var. cornigera


This spurge was shot from Chakrata area in August 2013..
Is this Euphorbia wallichii ??


After studying the description and drawing in the book ‘The genus Euphorbia L. (Euphorbiaceae) in India – A taxonomic revision’ by M.S. Binojkumar and N,.P. Balakrishnan, I confirm that it is Euphorbia wallichii. The authors have mentioned that in India it is found in J & K, HP, Uttarakhand and Sikkim at 2200 – 4100 m altitudes. Thus, the occurrence of the species at a lower altitude is interesting.
The photographs are wonderful.


This appears to be E. jacquemontii Boiss. The white midrib of leaves, few rays of pseudoumbels, ternate ray leaves, oblong ovate glands of cyathia, and sparsely warted ovary points to that species.


I have a feeling that fruits in the first photograph are tubercled (and not smooth), a feature found neither in E. wallichii nor E. jacquemontii. I request … to crop the first photograph from original image and upload clearer picture of fruit for confirmation by …


Here are cropped pics of the fruit.. hope they provide some hints..


I would tentatively suggest E. cornigera


It is necessary to examine mature fruits to determine. If the cylindrical processes on capsules are about 1 mm long, then it could be E. cornigera var. cornigera. If they are about 0.5 mm then it would be var. cognata.
Further the whole plant also needs to be seen to see the nature of branching.

Thanks, … The whole plant is here.


Thanks … My raising the doubts helped. In fact that is the beauty of this group. The members from expert taxonomists (incl. …, and others) to non botanists (like …) don’t hesitate to question an ID even if it has come from a top expert, and am happy that it has helped in the identification process. Having seen so much of E. wallichii in Kashmir Himalayas, I was somehow not satisfied with this being E. wallichii. Luckily a few young fruits (cropped and blown up) helped.

The hillsides were dotted with this beautiful spurge. I am not sure which of the Euphorbia species this is. Please advise.
Euphorbia sp.

I think Euphorbia cornigera


Yes, I also think E. cornigera.


I think this appears more closer to images and details at Euphorbia cashmeriana Royle




Flora of Chakrata 2012: Euphorbia for Id:  6 images.
This herbaceous plant was shot from Chakrata-Budher caves road on May 17, 2012. Height about 50-60 cms, leaves in whorls around nodes…hope to get the identification…


I hope Euphorbia cognata


I was thinking about Euphorbia wallichii.


Yes looks like E. wallichii, but long hairs on ovary are unusual.


May be Euphorbia cashmeriana Royle


This species is most probably Euphorbia cashmeriana Royle


.


I’d requested 37: 2 images.
Location: Rajouri j and k
Habit: Herb


Euphorbia sp.


Yes but which species of Euphorbia?


Euphorbia pseudosikkimensis (Hurus. & Yu.Tanaka) Radcl.-Sm.


Seems to be E.donii


That is synonym !


I think it is more closer to Euphorbia cashmeriana Royle as per images and details herein and as per comparative images at Euphorbia.


Both sp. looks so close.
