This is Arachis pintoi. I love this groundcover plant. It has a small green leaves with a small yellow flowers. Looks fresh! I took this photo in the morning when me and my husband went for jogging around campus few years ago.
Picture was taken in Bogor, 5 February 2012. First posted on Lensa Khatulistiwa (my old photoblog) at 26th October 2012.
