Appears to be some Selinum species but not finding a match as per species given in
Selinum candollei DC. (Himalaya (Kashmir to Sikkim)) (ambiguous synonym for Cortia candollei (Wall. ex DC.) Leute)
Selinum striatum C. B. Clarke (Nepal) = Oreocome striata (DC.) Pimenov & Kljuykov as per GRIN (2011)
Selinum wallichianum (DC.) Raizada & Saxena (No distribution given) = Ligusticopsis wallichianum (DC.) Pimenov & Kljuykov as per GRIN (2011)

Pl. check Himalayan species of Selinum L. sl – BioOne

May be some Angelica species.

I checked all species as per Checklist of Nepal
I think it is close to Angelica nubigena (C. B. Clarke) P. K. Mukh. as per POWO & GBIF (except for 2 specimens as given below, others are of Angelica apaensis R. H. Shan & C. Q. Yuan) & its high resolution images at

I guess Angelica nubigena (C.B.Clarke) P.K.Mukh. is the good match.

Finally I got more clarity after lot of search, from keys and details in Flora of Bhutan
This species is also quite close as far as leaves are concerned to Angelica cyclocarpa (C.Norman) Cannon as per details given in the link above.
Now I am sure about this being Angelica nubigena (C.B.Clarke) P.K.Mukh., after matching with the description.

I am now doubtful about its id as Angelica nubigena (C.B.Clarke) P.K.Mukh. bracteoles 4–10, linear 5–12mm and no mention of any bracts as per details in Flora of Bhutan

I tried all species of Heracleum in Checklist of Nepal as per following, but unable to place it:

Heracleum candicans

Heracleum canescens

Heracleum nepalense

https://www.gbif.org/species/3630331 (Heracleum brunonis (Wall. ex DC.) C.B.Cl.)

https://www.gbif.org/species/3629462 (Heracleum lallii C.Norman)

http://www.plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:943618-1 (Tetrataenium sublineare (C.B.Clarke) Manden)

http://plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:943871-1 (Tetrataenium wallichii (DC.) Manden)

FRLHT (Heracleum wallichii DC.)

On checking with keys in Flora of Bhutan lead me to Pleurospermum.
On further checking with keys of this genus at Pleurospermum lead me to Pleurospermum dentatum (DC.) C. B. Clarke which seems to match as per specimens from Nepal at GBIF
Flora of Bhutan gives habitat and elevation as below:
Moist open moorland slopes, disturbed rocky areas, 3050-4300m. August-September.
(Current name is Hymenidium dentatum (DC.) Pimenov & Kljuykov as per GBIF)

It looks like more closer to Hymenidium benthamii (DC.) Pimenov & Kljuykov
Syn : Pleurospermum benthamii (DC.) C.B.Clarke

Elevation is matching according to the FoC and also recorded in Phulchoki!

Flowers, flower head, leaves etc.- nothing matches with these images. I have checked this before hand.

Also does not matches with specimens at GBIF

Elevation has got a vast difference, like beyond 3000ft. and no record so far from Kathmandu Valley except for P. benthamii. Please look into this once!

In the mean time I shall check further for the possibility.

Yes, this will also be Hymenidium benthamii as per GBIFSpecimen.
Looks different from Hymenidium dentatum (Wall. ex DC.) M. G. Pimenov & E. V. Kljuykov as per GBIF specimens:

I have another that I can not ID. I thought it was Hymenidium benthamii but it is not.
I hope you can help again.

I guess Hymenidium benthamii (DC.) Pimenov & Kljuykov
Syn : Pleurospermum benthamii (DC.) C.B.Clarke

I agree with … as per GBIFSpecimen.

Yes, thank you both the specimen confirms ID.
