This is one of the cases where the correct name is not clear to someone

form Clerodendrum, on the other hand orthographical mistakes are to be
corrected, and Linnaeus doesn't replicate Burman's spelling is his
citation, so he didn't obviously intend to change the spelling. IPNI has
standardised on Clerodendrum, so presumably that is correct, but it's
not obvious why it is.

Consistency :-)

Seriously - that will be the justification, but God alone knows how
they came to that conclusion (I am sure that they don't). Anyway,
it doesn't matter, any more than Buddleia versus Buddleja.
