RE: mystery oxalis

I thought it may be Oxalis corniculata but taxonomists
are undecided as to how many spp. are actually included
in this rather cosmopolitan section.
Certainly the spp. is found everywhere, I've seen it growing in 
bushland miles from anywhere!

If it hasn't set seed, look for little pointed capsules sticking up from
the
plant mass, then carefully removing the plant by hand will 
do a pretty good job, dispose in a safe manner deep burial
incinerator etc....

You could spray with a glyphosate based herbicide, works pretty
well but you need to be a good aim in a garden!

Once you get a lot of it though it can be a real pest growing 
through most everything. It is usually brought in via contaminated
potting mix in plants brought from nurseries.  Look carefully
at other pots in a nursery not just the ones you intend on buying
to see what you may be bringing home as an extra passenger!!!

Other than that I'm not much help, if its spread is not to extensive
you'll probably get on top of it, 

good luck, Rod
