Taxacom: Which code (ICZN, ICN or something else) applies to Chromista?

Hi Doug, all,

Just a note that Acritarcha and Calcitarcha, supplied to you as groups
under Protozoa (zoological Code) are more accurately treated under the
botanical Code per their original establishing authors (membership is
probably a bit mixed in practice, being likely representatives of protista,
Chromista and others including likely green algae). Accordingly in my
latest version of IRMNG they are both back under Plantae, where they
started off in fact... So in general names in these groups can be left on
one side if you are compiling lists of available or unavailable zoological
names (with apologies for previous confusion).

Regards Tony Rees, IRMNG
