Mandevilla

Is it possible to add Dipladenia as a synonym, or maybe "Also Sold As" for Mandevilla? I've witnessed many arguments over the past couple of years with people saying that they are two different plants but according to the CoL, Dipladenia is a synonym of Mandevilla.

It isn't a true synonym because some dipladenia species have been reclassified as Rhabdadenia, Odontadenia, Pentalinon, and Galactophora.

Thanks zuzu, I didn't realize that.
