Location: Bombay Shola, Kodaikanal, Tamil Nadu
Altitude: ~2100 m
Date: 20/01/18
Habit: Herb
Habitat: Gregarious, on the roadside
Approx. height: 5 cm 
Insertion of leaves: Whorled
Flower diameter and length: 0.5 × cm 

It is certainly an Oxalis sp. Unlikely to be Oxalis corniculata L. because of the altitude like Bombay shola. (2100m).
Family : Oxalidaceae

Since the flower has reddish veins outside the possibility is Oxalis spiralis Ruiz & Pav. ex G.Don
This species will have many flowers on their pseudo raceme.  The photograph here does not show their actual nature.
Native to S.America and is a weed in most of the higher altitude hill stations in Kerala and Tamil Nadu.
