Euphorbia supina (A caustic weed)
Prostrate to ascending herb, often with a reddish spot in the centre of the leaf (but not always). Differs from the similar weed E. prostrata by having the stems uniformly hairy, not with hairs in longitudinal bands, and the tiny fruits are hairy all over, not just on the angles. Commonly found in cracks in paths.
