Thanks, Singh ji,

I think we have a similar observation at Flora of Chakrata-Gagea elegans for validation :: NS April 01

Keys in Flora of Pakistan lead me to Gagea lowariensis Pascher. As per this link, Flora of Pakistan states

"Gagea lowariensis, Gagea davlianidzeae and Gagea elegans are polymorphic, closely-related species within practically continuous areas, spread at different heights above sea level. Gagea lowariensis dwells usually above a forest belt (2500-3500 m). Gagea davlianidzeae and Gagea elegans grow on glades, along borders and under forest canopy, going down up to 1000 m in northern part of an area. The line of distribution between these taxa and Gagea granulose is not easy to define. Often, plants from this group of cognation are identified as Gagea lutea (L.) Ker-Gawl. which is absent in Siberia, mountains of Central Asia and in the Himalayas. Under the name Gagea lutea and Gagea elegans from the Himalayas 3 chromosomes numbers are specified: 2n = 72, 96, 132 (Koul & Khan, Sci. Cult. 35(12): 689-690. 1969; Koul &, Gohil, Phyton 15: 57-66. 1973).

In Gagea davlianidzeae, attributes of Gagea elegans (a narrow basal leaf) and Gagea lowariensis (the wide lower subinflorescence leaf) are combined; this may indicate hybridization. Possibly, the hybridization constantly takes place in this group. This may explain the similarity in habits and difficulty in differentiating the species and the diversity of chromosome numbers. It is accompanied by increase in the general sizes, width of leaves, degrees of branching of the inflorescence and quantity of flowers."

However, as per Catalogue of Life, it is considered as a syn. of Gagea lutea (L.) Ker Gawl.

Pl. see high resolution specimen at GBIF, to which it appears close.

Also looks very close to your specimens at Gagea elegans from Kashmir-GS08201906
