Susan, I think your original confusion was due to the font used on that website and this one. This font shows no difference between a small "l" and a capital "i," so you probably thought the name of the genus was Lochroma. The name of a genus has to begin with a capital letter, however, so Iochroma begins with an "i," not an "l."
As for the common name you prefer, you can propose a name edit, adding Iochroma as a common name, and give that name a thumbs-up. After you refresh the page, the one with the thumbs-up should be the one showing.
