I have photographed this plant at a nursery, but the system doesn't accept the genus Clerodendron, maybe it is now a synonym, but of what?
The name Clerodendron trichotomum var.fargesii is widely used on the web, even on supposedly reliable ones; f.ex.: http://www.theplantlist.org/tp... http://www.birminghambotanical...
Not so stupid, I hope. I was just telling a friend today that I never remember whether it's clerodendrum or clerodendron. I get it confused with rhododendron, I guess.
