I have been seeing this growing out of stone retaining walls on my walks. I am not sure if grows on the ground too-I am yet to come across one. The flower is tiny, not more than 1-2cm. The whole plant in the picture must be 6-7cm.
This photograph was taken on my phone in August this year.

I imagine if the leaves belong to the same plant?
It should be Argostemma verticellatum
Thank you ... for this ID.
Sorry for replying late-I was travelling and had limited access to the Internet.
I found out the only common name for Argostemma verticillatum is in Chinese 'Xiao xue hua'.
Are we aware of any English name?

just reminiscent  I had called mine Porelain flower before the id, your flower reminds me of porcelain beauties ...that's all
Two species of Agrostemma known in Uttarakhand.
Flowers with 4 petals.....A.sarmentosum; flowers with five petals...... A. verticillatum.
Both often grow together along streams, on moist walls in rainy season.

I found several of these growing as epiphytes on trees.
From Greek argos: white and stemma: wreath.

Yes, beautiful pics. Never seen on tree trunks in our area.
Thank you ... We have them on walls, rock faces, the ground and on the trees. These plants were growing on a wild pear tree.

It should be Argostemma sp. (Rubiaceae). Looks closer to A. verticillatum. Argostemma in eFI.
