Gahnia lacera Taxon needs curation correction?

I posted in Bug reports but no answer there yet, and it may be the wrong place for it.
A common New Zealand endemic plant species, Gahnia lacera, has become obscured, with a listing of “Critically imperilled - Endemic to Lanai” . Any advice on how to get that corrected, or explained if there has been a name change or something, would be much appreciated, as the species is now not included in my survey Projects

curation issues should be raised with a flag on the taxa. I see you have done that now… but should really only raise the one flag, if you have more to add to it, add another comment to the first one!

and it looks to be in error…
