I am attempting to validated names of the naturalised species list (http://www.nzpcn.org.nz/publications/Naturalised-list-06-new.pdf) and struggle with the following three, constantly rejected by ITIS, theplantlist.org and GBIF:
Sisyrinchium "yellow"
Lampranthus "Hunter Gully"
Sisyrinchium "blue"
Lampranthus "purple"
nzpcn.or.nz states that the names are not accepted. Can you help out with accepted synonyms or references? I am interested to know if there is a 'more' upto date version of the list and where the year of naturalisation on the individual species pages on http://www.nzpcn.org.nz is derived from.
Many thanks, Philipp
