Solved Unknown weed

Can anyone identify this weed please that keeps cropping up in my flower borders. I have searched online on weed identification sites but cannot see it. It has clover like brown leaves on thin stems. I found this one growing up through a patch of Osteospurms.

 

Some kind of Oxalis, maybe

 

Definitely Oxalis.

 

Thanks for quick replies. Much appreciated.

 

Oxalis pes-caprae has a reputation for being very difficult to eliminate once it has spread over an area of land The weed propagates largely through its underground bulbs and this is one reason why it is so difficult to eradicate, as pulling up the plant, even with the roots, can leave some of the bulbs behind. Soil in which the plant has grown is generally contaminated with many small bulbs.

 

Great! Doesn't sound too good. Just have to keep digging it out. Sometimes get the weedburner on them if not too near plants but that only kills the part on view not the roots.
