I believe the plants you are referring to are the sorrels- of the genus 
mame "Oxalis".  The oxalis comes from oxalic acid which gives the leaves 
of this plant a sour taste.  When I was a boy I remember my mother 
putting sorrel in her soups to give them a little tang.  

Here in the woodland areas of Chicago, Illinois (USA) the most prominent 
sorrel is the is the wood sorrel (Oxalis stricta).  It is a short little 
plant with small 5-petal yellow flowers.  As you said, its leaves are 
distinctly clover-like which droop and fold together at night. 

Best Regards,
