The characteristic feature of this species is that the mature fruits are densely covered by cylindrical processes. Young fruits as seen in the photo do show indications and appearances of the processes.
The warty surface of the ovary and fruits, which is characteristic of Euphorbia cornigera. In E. wallichii the ovary and fruits are smooth.

Yes .., Euphorbia lathyris, perhaps.
Yes .. It is Euphorbia for sure. Perhaps Euphorbia prolifera.
..., please supply a close up of cyathium showing glands (innermost flower-like structure). This species looks similar to E. wallichii but grows at lower altitudes ascending to around 2000m, whereas W. wallichii grows above 2500 m or so.
may be Euphorbia pilosa
.. Yes E. pilosa may also be possibility. In fact all  E. prolifera, E. pilosa, E. cornigera, E. cognata and even E. wallichii (omitted on the basis of its occurring at higher altitudes) look similar, and fruits and glands help in final distinction, that is why I have requested .. to get close up of cyathium for final identification.
I had taken a photo of the cyathium the other day, sir... but when one does not know the importance of a certain feature, it does not have any value.... I hope this helps or I'll see the next time I go to those parts of the sanctuary (if they are still flowering then..)
The plant has glands which are rounded on the outside, thus fits with Euphorbia pilosa of Flora Simlensis and FBI. Latter recognises three  varieties under pilosa: var. pilosa (under  which no specimen is cited from  India); var. cognata and var cornigera. These are now considered as three distinct species E. pilosa, E. cognata and E. cornigera. E. pilosa according to eFlora of Pakistan does not grow in our area being distributed in Mongolia and Siberia, where as both E. cognata and E. cornigera occur in Himalayas. 
Though fruit would have fixed the species conclusively but looking at slightly serrulate leaves, the plant appears to be Euphorbia cornigera Boiss. (syn: E. pilosa var. cornigera (Boiss.) Hook.f.)
VoF Week : Euphorbia pilosa: Euphorbia pilosa of Euphorbiaceae family
Clikced on 16th August` 12 while trekking down from Ghanghariya to Govind Ghat, CHamoli, Uttarakhand.

Euphorbia pilosa perhaps does not occur in Himalayas. This is likely to be E. corngigera.
Frank Smythe reports collecting Euphorbia pilosa from Valley of Flowers in 1937. I am not sure if it wasn't some other species. I also consider Euphorbia wallichii. Frankly I am not able to distinguish between them properly.
My first guess was E. wallichii only, so common at these altitudes, but I could see some warts in some of the young fruits visible. A mature fruit should decide conclusively.

Could this be Euphorbia cornigera (Family: Euphorbiaceae)??
: along Govindghat-Ghangaria Trail.

Grand pictures, ...
Fruits are clearly seen warty; Euphorbia cornigera.
blue fly and silvery raindrops
besides I counted at least five shades of green
any painter or embroiderer would appreciate these and can learn from it
or even textile designer or advertisement copy writers/illustrators...
all this besides the science ...
loved it
The beauty comes to light only after zooming. Great shots.
VoF Week: Euphorbia spp for ID please:
Found this Euphorbia spp. in Govindghat-Ghanghariya trail on 13.08.2012.
ID please.
Euphorbia cornigera I hope
VOF Week: Euphorbiaceae sp-2 along Govindghat-Ghangaria trail:   Euphorbiaceae sp along Govindghat-Ghangaria trail.
I think this should be Euphorbia cornigera only...
If all photographs belong to same plant then surely E. cornigera

Euphorbia cornigera Boiss.
along Govind Ghat - Ghangaria trail on 01 AUG 12
Nothing to say.
This Euphorbia species is a wild species shot near Khati village on way to Pindari glacier (2500m) in Uttarakhand.
Resemble to E.pilosa but determination from experts is needed. 

This species is Euphorbia cornigera Boiss., found in JK, HP, Uttarkhand and Arunachal Pradesh.
This Euphorbia species is also a wild species shot near Naini Tal (2000m) in Uttarakhand. It also resembles to E.pilosa but expert determination is requested.

This is Euphorbia cornigera L. The characteristic feature of this species is that the mature fruits are densely covered by cylindrical processes. Young fruits as seen in the photo do show indications and appearances of the processes.

This Euphorbia was shot during VOF Trekking, was very common in the area...
Is this Euphorbia wallichii ??
Again not E. wallichii
Fruits are warty
This is Euphorbia cornigera Boiss. Notice the warty surface of the ovary and fruits, which is characteristic of this species. In E. wallichii the ovary and fruits are smooth.

Euphorbia cornigera
(Family: Euphorbiaceae)
Location: along Govindghat-Ghangaria Trail.
Extremely beautiful pics ...
Yes, this is Euphorbia cornigera Boiss.

Kindly confirm ID
Species: Euphorbia cornigera
Location: Paddar Valley J&K
Altitude: Around 2500 
Yes, this is Euphorbia cornigera Boiss.
Kindly confirm ID
Species: Euphorbia thomsoniana
Location: Paddar valley J&K
Altitude: 3200 m
Close up of cyathia should help
The leaves don't suggest E. thomsoniana
Although not a good quality picture, had just tried to zoom the picture.
Fruit is clearly tuberculate
E. pilosa, E. cognata or E. cornigera
This is not E. thomsoninana.
The warted ovaries and capsules indicate that this is E. cornigera Boiss.

This tall Euphorbia was shot from Gobind Ghat-Ghanghariya Trek during VOF visit..
please give your opinion about the id..
I will try to share close up pics, if I could find any, to ascertain..
To me this looks like Euphorbia cornigera
Oh. Great to see the plant in large numbers!
Yes, this is most probably E. cornigera Boiss.

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.

I saw a couple of specimens of this beautiful Euphorbia on my walk on Saturday. Could this be E. cornigera? Please advise.
Euphorbia cornigeraHorned Spurge?

I think seems to match with images at Euphorbia cornigera

Yes. this plant is Euphorbia cornigera Boiss. var. cognata (Klotzsch.) Binojk. & N.P.Balakr.
Here the ovary is sparsely warty, whereas in var. cornigera the ovary and fruits are densely covered with conical warts.
This is found in JK, HP and Uttarkhand.

Euphorbia helioscopia

This appears to be Euphorbia cornigera Boiss. found in Kashmir Himalayas.

Saw this Euphorbia at Ghangaria trail, Uttarakhand in Aug 2018.
Requested to please provide ID, if possible. Is this E. cornigera?

Pl. check images and details at 
May be? 

It could be either E. cornigera Boiss. or E. donii Oudejans. Please check characters on live plants with my book on Euphorbia of India.
Thanks … for the feedback. Unfortunately, this is the only pic I have and it would not be possible to look at the live plants :(
