Rescue Orchid ID please

Hi,
what is this rather ugly and unruly species please? I rescued it from Sainsburys nearly dead, now it's flowering. The pseudobulbs are quite big, about mango-stone size, and the flowers small. The flowers are speckled maroon with a lemon yellow wavy lip that matures to white. I happen to hate anything brown or yellow but this one is excused for now




Thanks!

 

I think it is one of the Oncidium cultivars (used to be Odontoglossum) and a nice specimen and as you have found out, easy to grow indoors.

 

Thanks @strongylodon , I googled Oncidium and indeed you are spot on
