Access the NCBI Taxonomy classification of "stramenopiles".Some botanists replace the division name "Chromophyta" with "Chrysophyta". Some botanists replace "Ochromonadales" and "Ochromonadaceae" with "Chromulinales" and "Chromulinaceae". For many years, all uniflagellate chrysophytes (Chromulinales) were separated from all biflagellate chrysophytes (Ochromonadales) solely on the basis of flagellar number. Modern research indicates that this criterion does not reliably separate taxa, and there is no other basis to separate Ochromonadales from Chromulinales. Chromulinales (and Chromulinaceae) are the older names and are therefore for choice.
