Lovely catch catch nice to see the difference between two species.
Kindly read it as
Cerastium fontanum Baumg. var triviale (Link) Jalas (nullify the typo error in the passage)

Thanks Tanay for adding "a" to correct my typo error. I love you for such critical eye.

Dear Gurcharan ji,
This one doesn't look like Cerastium fontanum subsp. triviale to
me, which is now treated synonymous with Cerastium fontanum subsp.
vulgare. Petals are supposed to be shorted than sepals in that
species. However, in your flower the petals are distinctly longer than
the sepals.
To me it looks like Cerastium dahuricum (alternate spelling
Cerastium davuricum), with notched petals longer than sepals and stem-
clasping leaves

Tabish ji

Thanks for pointing out the petals length. It, however, does not look like C. davuricum in which the plants are much taller, leaves much broader at base (ovate) and clasping.

 My plant may be C. fontanum var. grandiflorum perhaps, the leaves are clearly elliptic-lanceolate. Let us continue the search.

After further scrutiny I have come to the conclusion that my plant identifies better with C. fontanum on account of two things:

The petals are longer than sepals

capsule is much longer than fruiting calyx

I think it will be Cerastium glomeratum as per discussions at Confusion between Cerastium fontanum subsp. vulgare and Cerastium glomeratum and Id request for this species of Arenaria

In fact, now Cerastium fontanum subsp. triviale (E.H.L.Krause) Jalas is considered a synonym of Cerastium glomeratum Thuill.
