I think yes as per images and discussions at Polygonatum verticillatum (L.) All.
For now, P. verticillatum is the only name that applies, but I really think P. leptophyllum is a better fit for this non-cirrhose plants with narrow leaves.
Thanks dear …, yes it matches P. leptophyllum because of its very narrow leaves.
Convallariaceae (asianflora.com)
All recent databases treat it as a synonym of P. verticillatum

I think it may be the same as at Polygonatum verticillatum for validation from Uttarakhand-GS26062022-6, with views from Dr. Floden as below:

Should we take it as Polygonatum leptophyllum (D.Don) Royle ?
Probably so. It would be the best name that matches this morphology.
But … all three major databases POWO, WFO, COL treat it as a synonym of P. verticillatum, as reported in my post above.
An accepted species may have numerous synonyms, differing in minor details, but we have to follow what established databases conclude, I would prefer us following POWO, but in this case all three major databases have the same opinion.
Waiting for the revision of the genus Polygonatum, especially in Indian context by Dr. Afloden in near future, so that we will be in a better position to sort our specimens.
There needs to be an international effort, especially within the Himalaya and eastward into China. My sampling was limited to plants exported years ago and cultivated in the UK. I think in the western Himalaya that there are at least three species under the name P. verticillatum and possibly more. Under P. cirrhifolium there are probably also 3 distinct species with the true plant only being found in the more arid regions of the northwest.

Not sure what to call this. Until the taxonomic issues of the former P. verticillatum in the Himalaya are taken care of there is no good name for some of these verticillate species there. There are multiple cytotypes with different base numbers and ploidy within those numbers (2n=28, 30, 56, 60, and higher), and then the phylogenetic issues of similar appearing taxa in different clades.
Polygonatum sibiricum Redouté ??
No, P. sibiricum is northeastern China west to Mongolia and into northeastern Gansu. It is a distinctive plant with glaucous leaves and pure white flowers.
I am enclosing the latest checklist from Nepal if it could be helpful to ID the sp.
3 images.
I’ll say that P. curvistylum definitely does not occur in Nepal. It is a species endemic to a small area of Sichuan and Yunnan provinces, China. I suspect the plant in question must be a lax-leaved P. graminifolium.
In that case the database in POWO, CoL, GBIF and efloraNepal/China need to be revised.
By the way I have noticed pink flowers only in the Net for P. graminifolium.
Polygonatum verticillatum in Europe and the Caucasus has trichomes along the abaxial veins of the leaves. In the Himalaya only P. geminiflorum has these trichomes. In China there are a few others that do, but the plants in the Himalaya referred to as P. verticillatum are glabrous or merely scabrous on the veins.
Thank you … for validating the ID. Polygonatum verticillatum (L.) All.
