I believe all the photos of H. phoeniceus are incorrectly identified. If you compare them with those of Pavonia hastata in our database you will see they are the same flower. Doing a google image search for P. hastata find numerous images matching those in our database, but the only images matching our database for H. phoeniceus are the one from our database. The most important clue that the images are wrong is in the images of the calyx and bracteoles.
Look at the calyx and bracteoles in our images of H. phoeniceus.
with these images on other websites. You'll see that H. phoeniceus should have numerous long thin bracteoles, which those in our database do not. http://hibiscus-malvaceae.blog...
