Calceolaria, also commonly known as Fimacho, acka Zapatillos. I can't help you with the species (I can barely keep track of the Ecuadorian ones, most of which are endemics), but I can tell you it's most definitely a native.
Thanks so much Lorax. I'm surprised (because I've seen it in disturbed areas) but happy to see it's native. I'll start digging around Calceolaria on line.
It's a native pioneer of disturbed soil - and actually also an indicator of soil health. Calcies are one of the first plants I see when new roads have been broken, and they'll only grow where that broken soil isn't contaminated with oil or fuel.
