Adam...you're right
According to Orchidwiz, the Den is 2-18"...and the Tricopillea is 5-17"...
I'll remove the Trichopillea from the list...but I WILL one day have it in my orchid room!
Now that my eyes are opened...I'm going through the descriptions on our existing list and notice a few just say "Medium" (my fault
got lazy) ...in checking these in Orchidwiz, I found some that will have to be moved to "no good for our project" in our list
Den lawesii - 10-18" - being moved
Oncidium ornithorhynchum - 20" - being moved
We are now back to having under 20 on the list...the new number is now 18
