Hi TonyR, Hey, you came very close to the identity of this plant! I asked a botany professor for its identity and it is Hemigraphis...
Hi, Thanks for the help! It doesn't have square stems though. But you were right about the flowering part! :) BTW, the underside of leaves is red.
Hi, I've noticed that this small lying plant tends to grow in very shady areas such as in the grooves of carpark lots over here in Singapore....
