It is confusing Janet, the photo material on the web often contradicting.
The pictures of 'Universidade de São Paulo' of Ucera nitida don't convince me, it doesn't feel right but reminds me of another plant I also photographed, I had put them in the same folder as they had a lot similarity, but its leaves were not shiny (when dry), more roundish and the teeth smaller, it also looks like the one on this site:

I think the one I posted before is Urera baccifera (based on the pictures of the fieldmuseum which must be a reliable source) and the second one Urera nitida, (based on the pics of the 'Universidade de São Paulo')
You had it spot on from the beginning!
