Thanks Jenny.

The leaves certainly look a pretty good match to me, but we've never
seen
any flowers - we didn't even know if it was a wild plant or a
cultivated
one. Interestingly, now that the light is failing, the leaves have
folded
down so that the leaf edges touch, which then makes the leaves
resemble the
flights of a dart. You can just see this happening on the leaves at
the
extreme bottom right of the photo that you pointed to.

That is a common feature of many (all?) members of the Oxalis genus.

If I could figure out what it needs to enable it to flower, I would
gladly
do the necessary as it's an interesting little plant.

Probably putting it in a good light will help. But watch it, many of
this genus are very rampant and are quite difficult to eradicate once
they have established a colony.
