I'm going to jump in here too, zuzu, with another related issue to consider while we're at it. H. rosa-sinensis is the species. We have the parent listed as Tropical Hibiscus right now which is the best way to get to the list when doing a search since the hyphen (aka minus sign) -sinensis seems to negate everything after and you don't get a list at all if you search by that name.
However, there are other species of Tropical Hibiscus as well. But when you just type "Tropical Hibiscus" into the search box, you don't get those other species. That's why some photos of Tropical Hibiscus went to Dave for moderation rather than you since you have only "Tropical Hibiscus" rosa-sinensis.
Something seems a bit off about that as well. I think this stems from dividing genera for moderating purposes? Not sure what to do about it.
