Oxalis caprina or Oxalis incarnata?

Dear Claude,

This was my mystery plant. I called it Oxalis sp. on the wiki and just 
wrote that Diana thought it could be O. caprina.  She was only speculating. 
Mine has started to dry up, but that may just be because I have stopped 
watering it. It is the longest blooming Oxalis I have. (October to April). 
Maybe I could keep it going longer had I kept watering it. Mine have liked 
shade better than sun too and they do fine with a summer dormancy. My tag 
says BX ? but I am wondering if my friend Jana gave them to me from some 
she got from the BX. Mine have what I thought at first was seed in the leaf 
axils, but then decided was bulbs even though they look different from 
the  bulbs in the pot. I conclude that my plant is the same as yours.

Cape Plants lists an Oxalis incarnata and it seems to be native to both 
summer and winter rainfall areas, has white or pale lilac flowers with a 
greenish tube. Not much from the description to nail it for me. The book 
says bloom from January to April so mine is blooming at the same time in 
this hemisphere as this plant does in South Africa if that is what it is. 
I'll be happy to correct the wiki picture and add this other possible name 
as well.
