It's true that many of the Polanisia species have been reclassified as synonyms of Cleome species, but our database entries are up to date. The Polanisia species listed there, including P. dodecandra and its subspecies, are still accepted names. The Catalogue of Life cites September 2015 as the date of the latest taxonomic scrutiny, so the "recent DNA study" would have to be very recent indeed to have refuted the existing data.

The status of botanical names is always subject to change, however, and our entries will be updated if and when these changes occur.
