Thank you, Samlav! The difficulties in understanding scientific names (or alternative names) for items isn't easily overcome except by pictures. Unfortunately, there is no trick to it, you just do what you are doing (look them up in the database). There *might* be cell phone apps out there designed to find and identify plant names, but I have never looked and I suspect it is unlikely such an app exists just yet.
Encouraging users to submit photos is the best way to accomplish what your are looking for, I think. Also, Dave has set the swaps up to generate a photo automatically (pulling from the database) any time you there is an entry with a link, which lends even greater importance for people to link their seed entries.
I am sorry I don't have an easy solution for you, but I hope it helps in some way!
