Ada invited Mr Black to smell two roses. He picked up one of the flowers and smelled it. There was a little fragrance (芳香), as if a gentle breeze was blowing against his face. He noticed that the flower was waiting to bloom. Then Mr Black was invited to smell another flower. After picking it up, he noticed that the rose had already blossomed. It looked like a big goblet (高脚杯) where the stamen (雄蕊) was hiding.
