Recently I posted about identifying a plant that I was trying to identify:
After several comments, I had narrowed it down to some type of Peperomia plant with peltate leaves. I researched for two days, and finally found an article which not only identified this plant, but also gave a bit of history.
Thanks again for ALL of your help, this was the last plant I had to identify, so my collection is now complete! (That is, until I start bringing more home...)
