All I had to do (after doing click back, tearing my hair out etc etc.) was simply enter the word gloriosoides in the search and bam there it was. I believe you can do this from any page in ATP. But most of the time you probably should enter the genus too. That is what I found out last night when entering my Japanese irises. I entered ensata then cultivar name and that worked well. If it wasn't there I had to put the name in then.
Anthony, just type in gloriosoides in the ATP search box and click on Lily (Lilium speciosum var. gloriosoides). When that page comes up there is a place near the bottom to click for your picture upload. It will go through the moderators and I will be happy to approve it.
I'll make it easy for you:
Showy Lily (Lilium speciosum var. gloriosoides)
Click on upload a photo; then on upload an image.
