I think they were lighter yellow or white earlier. I'm not sure because I didn't notice it was blooming until I smelled it and started trying to track down the smell. The pictures in the links you posted Lin look just like it so I think that is it. I do remember being given 'dama de noche' or 'galán de noche' which is Lady of the Night and I had no idea what I did with it. I thought this might have been it but looking it up in Spanish it is a different plant.
https://es.wikipedia.org/wiki/... It may be that every area has a different name for them or just my memory is bad. Thank you for identifying it for me. I really love the smell, it spreads through the bathroom upstairs from the roof garden and would probably fill my bedroom if I had the doors open and turned off the AC. Maybe if it blooms in the winter. It has been just sitting there in that pot for a year or two without blooming, I've no idea what kicked it into gear. I will try and give it more attention now.
