I just posted a picture of a leaf from a sick purple oxalis on
alt.biaries.pictures.gardens. It's leaves have dots of a yellow
powderish material (actually looks a lot like pollen) on the bottom
side. The leaves are deformed and eventually die back. Any thoughts
on the cause and a cure? Barring a better option, my current strategy
is a trip to the trash can.

Even without looking I can tell you that this is Rust.
What you can see are the fruiting bodies full of spores. Remove all the
leaves carefully and destroy.
If you only have a pot or two I would either tip the pot upside down and
remove the top inch of compost, or better lift the bulbuls and rinse them
in a fungicide and replant in fresh compost, then spray every couple of
weeks with a fungicide to prevent the rust taking hold again.

Thanks. I lifted the bulbuls and soaked for a few minutes in a captan
solution. I'll repot and see how they do. The only problem now is
that I have enough bulbuls for many more pots than I started with. . .

Try a few outside when the weather permits, They can look great, and if they
don't live through the winter.what the hell you will still have plenty from
your pots.
