Hi Ina, There is a yellow flowered Sparaxis hybrid in the trade. Someone once gave it to me. It was a good bloomer and looked a lot like yours. There is a photo of a yellow one by Paul Tyerman on the wiki Sparaxis hybrids page. When my Sparaxis showed signs of virus, I had a number of the ones in my garden tested and they told me the yellow one was virused which surprised me since it looked just fine. It made me realize that some people may sell virused plants unknowingly. This one didn't show signs of virus (or at least not the ones I was looking for) and grew well. Mary Sue
