I am happy with the original answer.
It was a perfect answer.
Because I am dyslexic I often see things that aren't there, so to speak. Before I asked the question I had been looking at the genus Amaryllis and finding Hippeastrum; then looking at Hippeastrum and finding Amaryllis
I seriously thought it was me. Can't tell you how many times I went back and forth to see if the words would look different. Now that I know there are two genera, I can rest easy.
Short funny episode:
Driving down Abercorn Street I passed the Jewish Community center where there was a sign advertising "Swiss Lemons". That didn't look right so I turned right onto DeRenne and drove around the block; yep, sign still says "Swiss Lemons".
It was maybe the 3rd or 4th time around the block that my brain finally registered what the sign actually read..."Swim Lessons". See, dyslexia can be fun if you do it right!
So it was with the Amaryllis/Hippeastrum until you drove around the block for me and helped me to see the answer.
